When you choose a piece of jewelry, you are choosing more than an accessory. You are choosing something that will sit against your skin, follow you through everyday moments, and celebrate the milestones you will remember for years to come. Understanding the difference between fine jewelry and fashion jewelry helps you decide which pieces belong in your jewelry box, which belong in a keepsake drawer, and which are meant to be passed down as heirlooms. Although both categories have their place, they are created with very different intentions. The key differences come down to materials, durability, craftsmanship, and the purpose each piece is meant to serve. What Is Fine Jewelry? Fine jewelry is crafted from precious metals such as solid gold, sterling silver, platinum, and alloys of white gold or rose gold. These pieces often feature genuine gemstones like sapphires, rubies, topaz, opals, and natural gemstones that have been shaped by skilled artisans. Even lab-grown diamond accents or small pavé details carry a level of quality that lasts for generations. Fine jewelry pieces are made to endure. They are durable, high-quality, and designed to hold their beauty through everyday wear. When cared for properly, they do not tarnish, discolor, or fade. Their craftsmanship allows them to become heirloom pieces in time. This is why engagement rings, wedding rings, tennis bracelets, stud earrings, and other high-end pieces belong in this category. Their value comes from both the precious materials used and the artistry behind their creation. What Is Fashion Jewelry? Fashion jewelry, often referred to as costume jewelry, is made from base metals or inexpensive materials. These may include brass, copper, or zinc, combined with synthetic stones such as cubic zirconia. Gold-plated or vermeil finishes offer the look of fine jewelry at a lower price point, but they do not have the same longevity as solid gold or sterling silver. These pieces are often chosen for trend-driven styling or special occasions when you may want a bold look without the commitment of a higher price tag. The materials are lighter, the price tag is lower, and the intention is different. Fashion jewelry is meant for now, not forever. Because they rely on metals that can discolor or tarnish more easily, and because plating can wear down with time, these pieces require more cautious jewelry care. Exposure to lotion, perfume, or water can accelerate wear, especially if you have sensitive skin. The Key Differences: What Truly Sets Them Apart 1. Materials Fine jewelry uses precious metals and precious stones.Fashion jewelry is made from base metals, synthetic stones, and gold-plated or vermeil finishes. Fine jewelry includes: 14k gold White gold Rose gold Sterling silver Rhodium-plated finishes Precious gemstones such as rubies, sapphires, and topaz Fashion jewelry includes: Base metals Gold-plated or vermeil coatings Synthetic stones or cubic zirconia 2. Durability Fine jewelry is designed for everyday wear and long-term beauty. It resists tarnish, maintains its shine, and can be passed down.Fashion jewelry is more susceptible to discoloration and tarnish, even with proper care. 3. Craftsmanship Fine jewelry reflects time-honored craftsmanship and attention to detail, often created by skilled jewelers and gemologists.Fashion jewelry is produced more quickly, usually with standard settings and mass-made components. 4. Longevity and Purpose Fine jewelry becomes part of your story. It celebrates engagements, anniversaries, milestones, and meaningful moments.Fashion jewelry is meant to complement a trend or complete a temporary look. 5. Price Point Fine jewelry is an investment because of the precious materials and craftsmanship.Fashion jewelry has a lower price point because the materials are less expensive. How to Tell the Difference When Shopping A hallmark or metal stamp is one of the clearest indicators of fine jewelry. Look for marks like: 14k 18k Sterling or 925 Plat In contrast, fashion jewelry may be stamped with: GP (gold plated) GEP (gold electroplated) HGP (heavy gold plate) No stamp at all When in doubt, consult your local jeweler. We can help you understand which pieces belong in the fine jewelry category and which fall into the fashion jewelry category. Choosing the Right Jewelry for You There is no right or wrong type of jewelry. Each plays a role in a well-rounded collection. Choose fine jewelry when: You want something to last a lifetime You prefer precious materials You are choosing an engagement ring or a wedding ring You want a piece worthy of becoming an heirloom Choose fashion jewelry when: You want fun, trend-driven pieces You want to experiment with color You are dressing for a theme or special occasion You want lightweight pieces with a lower price tag Fine jewelry is a long-term relationship. Fashion jewelry is a moment of play. Both can bring joy to your everyday life in different ways. Caring for Each Type Proper care extends the life of any piece of jewelry. Fine jewelry requires: Gentle cleaning Occasional professional maintenance Care around abrasive surfaces Fashion jewelry requires: Avoiding water Keeping lotion, perfume, and oils away Wiping gently after each wear With the right jewelry care routine, even gold-plated or gold vermeil pieces can look beautiful for years. Fine Jewelry is in Our Name At Adam Foster Fine Jewelry, we believe jewelry reflects who you are, how you live, and what you love. Your collection can include both high-quality fine jewelry pieces that last a lifetime and fashion jewelry that adds spontaneity and fun. With a thoughtful approach to craftsmanship, materials, and care, every piece of jewelry can bring beauty into your life.

Heirloom jewelry holds a different kind of beauty. It is more than gold, gemstones, or intricate designs. It carries the touch of family history, the memory of loved ones, and the weight of stories that live long after the moment they began. When someone brings us a piece of heirloom jewelry in our St. Louis studio, it arrives with more than sentimental value. It represents a legacy. The Heart of Heirloom Jewelry At its core, heirloom jewelry is any piece that has been handed down through family members. It may be an engagement ring worn for decades, a brooch chosen for a wedding day, a pair of sterling silver earrings from a grandmother’s jewelry box, or a locket that has quietly held its secrets for generations. What separates heirloom pieces from the rest of a jewelry collection is not only age, but meaning. A piece of heirloom jewelry carries emotional value that far outweighs its monetary value. It is a sentimental piece that has stood the test of time. Why These Pieces Matter Heirloom jewelry pieces tell a story. They witness milestones such as graduations, birthdays, and weddings. They hold the memory of family members who once wore them, touched them, or cherished them. They travel from one generation to the next with a sense of continuity, becoming symbols of love, resilience, and tradition. Some pieces feature precious gemstones like sapphires, rubies, or precious stones set in precious metals. Others are simple, delicate, and made from sterling silver. The beauty lies not in extravagance, but in connection. Craftsmanship That Endures Many heirloom pieces were crafted during a time when fine jewelry was made slowly, thoughtfully, and with exceptional craftsmanship. Jewelers carved details by hand, shaped every curve with care, and worked with gemstones as if each one were a treasure. This level of artistry allowed heirloom pieces to endure for decades, even centuries. Durability plays a major role in why an heirloom ring or necklace can be worn for so long. The combination of quality materials and skilled workmanship ensures that family heirlooms do not simply survive but continue to shine. The Emotional Value and the Financial Value While some heirloom jewelry carries significant financial value, the emotional value is almost always greater. A piece does not need to have a high USD appraisal to be considered a family heirloom. Sometimes, the simplest heirloom jewelry piece has the deepest meaning because of who wore it or when it was gifted. Many families choose to have an appraiser evaluate their heirloom jewelry to better understand its financial value. This can be helpful for insurance, estate planning, or simply to learn more about the origins of a special piece. Repurposing and Preserving the Story Not every heirloom arrives in perfect condition. Time can leave its mark. A prong may need strengthening, wedding rings may need resizing, or a brooch may need a new clasp. In other cases, a family may want to transform an heirloom jewelry piece into a new piece without losing its soul. At Adam Foster Fine Jewelry, we are one of the few jewelers who welcome heirloom repurposing. We can take the gemstones, precious metals, or design elements you cherish and gently reshape them into something meaningful for today while preserving your family legacy. A ring can become a pendant. A locket can be restored. Precious gemstones can be set into a modern band or kept exactly as they are. Repurposing ensures that the story continues. Heirloom Jewelry for Future Generations When you pass down a piece of heirloom jewelry, you are not only gifting a special piece. You are giving future generations a reminder of where they come from and who came before them. A family heirloom becomes a touchstone during special occasions such as anniversaries, weddings, or the birth of a child. Some families start their own tradition by choosing a meaningful gemstone or birthstone, incorporating engraving, or marking a milestone for the next generation to one day inherit. Choosing Today’s Pieces With Tomorrow in Mind Not all heirloom pieces begin as heirlooms. Sometimes they start as a gift, a moment, or a single decision. Engagement rings, wedding rings, lockets, or statement pieces can become tomorrow’s treasured heirloom ring. When choosing fine jewelry today, many people consider both personal meaning and long-term durability, selecting pieces that feel worthy of becoming a lasting part of the family tradition. Honor the Past While Creating Something Unmistakably Yours Heirloom jewelry reminds us that beauty can hold memory. It carries the laughter, challenges, vows, and moments that shaped the people we love. Whether it is a ruby ring passed down by grandparents or a new piece created from repurposing an older design, heirloom jewelry tells a story that continues long after we are gone. If you have an heirloom jewelry piece you would like repaired, restored, or thoughtfully transformed into something new, our studio is honored to help. We treat each piece as if it were our own, preserving the history while crafting its future.

One of the quiet joys of fine jewelry is discovering how certain colors seem to come alive on your skin. When the right metal or gemstone meets the right person, it feels effortless. It softens, brightens, or balances your overall look in a way that feels personal rather than styled. Many people ask us how to choose the best jewelry color for their skin tone, eye color, or hair color. While there are helpful guidelines, the most important piece is simple: the perfect jewelry is the one that makes you feel most like yourself. As makers and artists, we have spent years observing how color behaves in natural light and how different tones interact with the warmth or coolness of someone’s complexion. Below are thoughtful ways to explore jewelry colors through the lens of your unique skin undertones and personal style. Understanding Skin Tone and Undertones Skin tone and undertones work together, yet undertones often matter more when choosing between white gold, yellow gold, rose gold, or sterling silver. Undertones fall into three categories: cool undertones, warm undertones, and neutral undertones. You can notice yours by looking at your skin in natural light and observing the hue beneath the surface. Cool Skin Tones If your skin carries hints of pink, red, or blue, you likely have cool undertones. Jewelry colors in the white metals tend to complement you beautifully.Think white gold, platinum, and sterling silver jewelry. Cool tones bring out brightness in the skin and create a clean, luminous effect. Gemstones like sapphire, amethyst, topaz, and other cool or jewel-toned stones add elegance without overwhelming your natural coloring. Warm Skin Tones If your skin reflects golden, peach, or olive hues, you may have warm undertones. Yellow gold suits warm skin tones especially well, enhancing the richness already present. Gold jewelry creates a lovely harmony with warm skin, and earthy tones become radiant: citrine, garnet, rose gold jewelry, and even earthy greens feel at home here. Neutral Skin Tones If you see a mix of both warm and cool hues, you likely have neutral undertones. Neutral skin tones enjoy easy versatility. Both white gold jewelry and yellow gold can work effortlessly, letting you fluidly switch between cool sophistication and warm glow. Neutral undertones also welcome colorful gemstones. Sapphire, opal, amethyst, citrine, or even unexpected shades become part of a balanced palette. How Hair and Eye Color Influence Jewelry Choices Jewelry has a conversation with more than your skin. It interacts with your hair color and eye color, shifting your overall appearance. Blonde Hair Soft golds and rose gold add warmth, while silver jewelry brings clarity and brightness. For blondes with green eyes, sapphires and emerald-like greens can be especially striking. Brown Hair Brown hair creates a rich backdrop for many jewelry colors. Yellow gold deepens the glow of brunette tones, while white metals create contrast. Gemstones like amethyst, sapphire, or topaz shine beautifully. Green Eyes or Brown Eyes Color theory can be useful here. Green eyes respond well to purple hues like amethyst or the warm shimmer of gold jewelry. Brown eyes are naturally warm and pair beautifully with rose gold, yellow gold, or colorful gemstones that offer contrast. When Personal Style Matters More Than Undertones Even the best color analysis cannot compete with personal style. Some people feel most themselves in dainty studs or a simple white gold chain. Others prefer statement pieces that bring energy to their look. Jewelry design is deeply personal, and your instinct is often your best guide. If you love the quiet strength of sterling silver, wear it proudly. If you are drawn to the romantic glow of rose gold regardless of undertones, let that be your guide. Jewelry is not only an accessory. It is an expression. Mixing Metals: A Modern, Effortless Approach One of the most common questions we hear is whether it is acceptable to mix white metals with yellow gold or rose gold. The answer is always yes. Mixing metals adds depth, individuality, and a sense of ease to your jewelry collection. Layering jewelry colors allows you to pair engagement rings with wedding bands in contrasting metals or create an earring stack with multiple tones. This approach has a natural artistry that feels modern without losing its timelessness. Choosing the Right Jewelry for Everyday Wear The best jewelry color is the one you enjoy reaching for each morning. If you prefer versatility, white metals often blend with many outfits and seasonal palettes. If you love warmth, yellow gold might become your signature. If you enjoy color, gemstones like sapphire, amethyst, or citrine can bring life to your look. Think about your lifestyle, the clothing you gravitate toward, and the kind of piece of jewelry that makes you feel at ease. Comfort is part of beauty. A Note on Custom Work If you are still unsure which jewelry colors suit you or you want to explore combinations that feel uniquely yours, we welcome you into our St. Louis studio. We can design rings, necklaces, or studs that echo your skin tone, personal style, and the textures or colors you love most. Your jewelry should feel like it was made for you because with us, it is.

When it comes to choosing a diamond, shape is one of the first and most defining decisions. The shape of a diamond affects more than just appearance. It influences how the stone catches light, how large it looks, and how it reflects your personal style. Let’s take a closer look at the most popular diamond shapes, from timeless classics to modern statements. Whether you're dreaming of a solitaire, exploring halo settings, or designing something entirely one-of-a-kind, this guide can help you find the perfect diamond for your ring. Round Brilliant Cut The round brilliant cut diamond is the most popular diamond shape in the world, and for good reason. With 57 or 58 facets precisely arranged to maximize scintillation, it offers unrivaled brilliance and fire. This classic shape suits nearly every setting and hand, making it a universal favorite for engagement rings. It’s also the standard against which all other shapes are measured by the GIA. Oval Diamond The oval cut blends the sparkle of a round brilliant with a graceful, elongated shape that flatters the finger. Its larger surface area can make the stone appear bigger than its carat weight, making it a popular choice for those who want impact without going over budget. Its soft rounded edges also lend themselves beautifully to both vintage and modern styles. Emerald Cut Known for its clean lines and elegant step-cut facets, the emerald cut diamond reveals a distinctive hall-of-mirrors effect rather than dazzling sparkle. This rectangular shape feels sophisticated and architectural, often chosen by wearers drawn to understatement and clarity. With its broad, open table, cut quality and inclusions become especially important when selecting an emerald cut. Asscher Cut A close cousin to the emerald cut, the asscher cut diamond is a square shape with beveled corners and the same step-cut structure. Popular during the Art Deco period, it has a vintage feel that looks stunning in symmetrical, geometric settings. The deep pavilion and layered facets create a bold, elegant look with depth and drama. Cushion Cut The cushion cut diamond, sometimes called a pillow cut, is beloved for its romantic, soft rounded corners and large facets that offer a gentle, glowing sparkle. Cushion cuts come in both square and rectangular shapes, and have become a favorite for antique-inspired and halo designs. A cushion cut diamond balances brilliance with a hint of old-world charm. Princess-Cut Diamonds The princess cut is a modern classic with a sharp square shape and brilliant facets that maximize sparkle. Often set with prongs to protect its corners, this cut is ideal for clean, contemporary ring designs. Its symmetrical form also lends itself well to side stones and bold, graphic settings. Radiant Cut Combining the fiery sparkle of a round brilliant cut with the geometry of an emerald cut, the radiant cut diamond offers the best of both worlds. With a faceted pavilion and beveled corners, it creates stunning brilliance and looks equally striking in both rectangular and square styles. A radiant cut is especially well-suited to halo settings and side stones. Pear-Shaped Diamonds Also known as teardrop diamonds, pear-shaped diamonds feature a unique oval shape that tapers to a single point. This shape elongates the finger and makes a bold, unexpected statement. When set with the point facing outward, it creates a slimming effect and an elegant, artistic silhouette. Marquise Cut Legend has it that the marquise shape was designed for Louis XV, who wanted a diamond to match the smile of his mistress, the Marquise de Pompadour. With its elongated shape, pointed ends, and dramatic presence, the marquise cut creates the illusion of a larger stone and adds vintage glamour to any diamond ring. Its curved sides and sharp tips require a well-made setting to protect the points and enhance its symmetry. Heart-Shaped Diamond The heart-shaped diamond is the ultimate romantic gesture, balancing playful symbolism with serious sparkle. With a cleft at the top and a rounded bottom, it requires precise cut quality to achieve symmetry and brilliance. While it is rarer, this fancy shape is ideal for someone who wants a unique shape with unmistakable personality. Fancy Shapes and Personal Style All of the diamond shapes that fall outside the traditional round brilliant are known as fancy shapes. These include the pear, marquise, cushion, asscher, radiant, heart, and princess cuts. Each shape offers a different personality, sparkle pattern, and profile, and the best choice comes down to what speaks to you. Shape also influences how a diamond is set. A bezel may frame a modern oval, while prongs might elevate a princess cut. A halo can make a small marquise feel grander, while a clean solitaire lets a cushion cut shine. Cut to Reflect You At Adam Foster Fine Jewelry, we believe that every diamond begins as a rough diamond full of possibility, and the magic lies in shaping it into something personal. Whether you’re drawn to the timeless glow of a round brilliant diamond or the sleek sophistication of a square emerald cut, we help you choose with clarity and confidence. All of our diamonds are selected for their beauty, integrity, and precision. We’ll guide you through understanding carat weight, light performance, and design so your final piece feels true to your story. Ready to see them in person?

There’s no perfect number. What matters most is that it’s the right ring for the right person, and is one that aligns with your values, your style, and your financial situation. That said, if you’re looking for a number, the national average spend on an engagement ring in the U.S. is currently around $5,000 to $7,000. But that figure is just a benchmark, not a requirement. Some clients spend less than $2,000, others well into the five-figure range. It all depends on your engagement ring budget, your priorities, and your love story. Let’s explore the history, trends, and options that influence how much you might choose to spend and how to make that amount work beautifully. Where the “Three Months’ Salary” Idea Came From The three-month salary rule isn’t an ancient tradition. It was a marketing campaign launched by De Beers, the diamond company that famously coined “A diamond is forever.” During the Great Depression, they encouraged spending one month’s salary on a diamond engagement ring to boost diamond sales. By the 1980s, that “rule” had stretched to two or three months and stuck in pop culture. But this so-called rule of thumb was never about love. It was about selling more diamonds. Today, most jewelers agree that your financial goals and shared values matter more than an outdated marketing slogan. What Factors Impact the Ring Price? When you’re engagement ring shopping, you’ll quickly see how many variables affect the price tag. Two rings may look nearly identical to the naked eye, yet differ by thousands of dollars. Here are some of the biggest factors that influence price: Center stone: A natural diamond generally costs more than a lab-grown diamond, even at the same carat weight. Meanwhile, gemstone options like sapphire, moissanite, or rubies may offer dramatic beauty at lower price points. Stone quality: Even subtle differences in cut, color, clarity, and inclusions can significantly impact how a diamond sparkles and its associated cost. Metal choice: Platinum and yellow gold rings are typically more expensive than sterling silver. Ring design: Intricate settings, pavé bands, incorporating heirloom stones, or hidden halos may add to craftsmanship and cost. Retailers: The store you buy from matters. Large jewelry stores often carry markup-heavy inventory. Boutique jewelers like Adam Foster offer a more tailored approach with high-quality pieces at honest, transparent prices.   How to Set Your Engagement Ring Budget There’s no single “right” number. But here’s how to think through it with intention: Review your financial situationTake stock of your savings, income, and existing obligations like student loans or other wedding planning costs. A ring should never derail your financial health or be the reason you rack up unnecessary credit card debt. Know your prioritiesAre you dreaming of a 2-carat diamond engagement ring or an antique-style sapphire in a vintage-inspired setting? Would you rather invest in a large piece now or put more toward wedding bands later? Explore alternativesModern couples are increasingly choosing lab-grown diamonds or diamond alternatives like moissanite for ethical and budget reasons. These stones often look identical to mined diamonds to the naked eye, at a fraction of the cost. Talk to a jeweler you trustA good jeweler will work with your budget and vision, helping you understand the tradeoffs between carat, cut, clarity, and more. At Adam Foster Fine Jewelry, our team can guide you through ring style options at all price points, with no pressure.   What Are Most People Spending? The average cost of an engagement ring in the U.S. hovers around $6,000, but the average amount varies significantly by region and lifestyle. In major cities or among clients seeking larger carat diamond rings, the spend may be closer to $10,000 or more. Other couples may stay under $3,000 and still walk away with a perfect engagement ring that reflects who they are. At the end of the day, these are personal decisions. The right ring is the one that fits both your love story and your budget. Engagement Ring Shopping Tips Start early: If you’re planning a proposal, begin shopping a few months in advance. This gives you time to explore custom or trending styles and avoid Black Friday rushes or shipping delays. Factor in future costs: You may also want to set aside funds for resizing, insurance, or pairing the ring with a wedding ring down the road. Think long term: This ring will be worn every day for years to come. Choose quality and meaning over trends or short-term savings.   Making the Most of Your Budget At Adam Foster Fine Jewelry, we believe beautiful rings can—and should—exist at all budgets. Whether you’re looking for a timeless diamond engagement ring, a vibrant sapphire center stone, or a modern design set in yellow gold, we’ll work with you to find or create a piece that feels right. Our custom designs, handcrafted in our St. Louis studio, allow you to celebrate your story with intention, creativity, and clarity. No gimmicks, no salary rules. Just beautiful, lasting jewelry.

In short, to be really thorough, clean once a week at home, and then have it professionally cleaned every six months. Your engagement ring is one of the most meaningful pieces of jewelry you’ll ever wear, and with that significance comes the need for proper care. Whether it’s a brand-new diamond engagement ring or a beloved heirloom, regular cleaning helps preserve its brilliance and prevents the slow build-up of grime, lotion, and everyday debris that can dull its sparkle or damage the setting over time. Below, we’ll walk you through how often to clean an engagement ring, how to do it safely at home, and when to seek professional cleaning from a local jeweler. The Weekly At-Home Cleaning Ritual Most rings benefit from weekly at-home cleaning, especially if you wear yours daily. Between hand lotions, soaps, cooking oils, or simply touching your face, a surprising amount of build-up can collect on the surface of a ring, especially in engagement ring settings with pavé or small diamonds. That build-up not only reduces the luster of the stone but can also cause skin irritation over time. The good news: cleaning your ring at home is simple and safe when done the right way. What You’ll Need: A small bowl of warm water A few drops of gentle dish soap (not bleach-based) A soft-bristled toothbrush A lint-free cloth (avoid paper towels, which can be abrasive) Steps: Mix a mild cleaning solution using warm water and dish soap. Soak your engagement ring for 15–30 minutes to loosen grime. Gently brush all surfaces and crevices, paying close attention to prongs and pavé areas. Rinse under lukewarm running water. Dry with a lint-free cloth. Avoid: household cleaners like bleach, acetone, or baking soda, as these can discolor metal or damage delicate gemstones. Harsh chemicals may also degrade rhodium plating on white gold over time. When to Seek a Professional Ring Cleaning Even with consistent at-home care, your ring deserves a deeper clean every so often. A good rule of thumb is to bring your engagement ring in for professional cleaning every six months. At Adam Foster Fine Jewelry, our studio offers complimentary cleaning services that restore each piece’s original shine while inspecting the setting for any wear. Our professional ring cleaning includes: Deep cleaning with ultrasonic jewelry cleaners (only when safe for your gemstone) Polishing to restore the original luster of gold rings Inspection of prongs, small diamonds, and pavé settings Optional rhodium re-plating for white gold to prevent discoloration We also recommend scheduling a jewelry cleaning and appraisal annually with a certified gemologist, especially for high-value rings or heirloom pieces. Keeping a Cleaning Schedule If you want to avoid buildup or discoloration, consistency is key. Recommended Cleaning Schedule: Weekly: At-home cleaning with warm water and dish soap Every 6 Months: Professional cleaning with your local jeweler Annually: Full jewelry cleaning and gemstone appraisal Setting reminders on your calendar or tying your cleaning schedule to anniversaries or seasonal closet swaps can help keep your jewelry pieces sparkling without the guesswork. Bonus Tips for Engagement Ring Care Remove your ring before applying lotion, handling raw food, gardening, or cleaning. Store your ring in a soft cloth pouch or ring box when not in use. Avoid ultrasonic jewelry cleaners at home unless you’re sure your ring’s setting and gemstone can handle it. Some delicate stones or antique rings require special care.

A Subtle Art, Not a Guess Whether you’re shopping for engagement rings, slipping on a wedding band, or surprising a loved one with custom jewelry, the correct size is everything. A ring should feel like it belongs at the base of your finger. Never too loose, never too tight, and always just right. If you're not sure how to measure ring size—or you're helping someone else find theirs—you're in the right place. We are experts here at Adam Foster Fine Jewelry. Below, we’ll walk you through simple methods, tips, and tools for getting an accurate ring size from home, as well as what to expect when working with your local jeweler. Understanding Ring Size Basics Let’s start with the essentials. In the United States, ring size is typically measured in whole and half sizes, from size 3 up to 13 and beyond. Each size represents a specific diameter of the ring, and even a difference of half a size can affect how comfortably a ring fits. US ring size vs. international ring size: If you’re comparing sizes from overseas jewelers, use a ring size conversion chart for clarity. Men’s ring sizes vs. women’s ring sizes: These may vary, but there’s no general rule as finger size is unique to the individual, regardless of gender. That being said, the average ring size for women is typically between size 6 and 7, while men often fall between size 9 and 11.   How to Measure Your Ring Size at Home You don’t need to leave the house to start figuring out your ring size. Whether you're browsing for a new piece or preparing for a secret gift, these techniques can offer a fairly accurate measurement. 1. Use a Piece of String or a Strip of Paper Wrap a piece of string or a strip of paper around the base of your finger (where the ring will sit). Mark where it overlaps, then lay it flat and measure the length in millimeters. Use a ring size chart to match your measurement to the corresponding size. Be sure the string slides over your knuckle comfortably. Measure at the end of the day, when your fingers are slightly larger. If you’re between sizes, size up for a more comfortable fit.   2. Measure a Ring You Already Own If you have an existing ring that fits the intended ring finger, you can measure its inside diameter and compare it to a printable ring size chart or a ring size guide. Just make sure the ring you're measuring matches the ring style you’re planning to buy. 3. Try a Printable Ring Sizer Many jewelers offer a free ring sizer tool. These templates allow you to either place a ring on a chart or cut out a sizing strip to wrap around your finger like a measuring tape. Be sure your print settings are set to 100% scale for an accurate ring size. Ring Sizing Tips from Our Jewelers Here at Adam Foster Fine Jewelry, our team of expert jewelers and master jewelers has helped countless clients find their perfect fit. Here are a few of our favorite ring sizing tips: Time of day matters: Finger size fluctuates throughout the day. Measure at the end of the day when your fingers are largest. Temperature affects fit: Warm fingers swell slightly, while cold fingers contract. Aim to measure in a neutral climate. Wider bands require a larger size for a comfortable fit: A solitaire ring will fit differently from a bold custom design. When in doubt, visit a local jeweler for an in-store fitting: It’s quick, precise, and gives you peace of mind.   When Do You Need a Resize? Even with careful measuring, ring resizing is sometimes part of the journey. Maybe your finger size has changed, or your grandmother’s ring is just a little too snug. Our jewelry services include precise resizing for engagement rings, wedding rings, and other fine pieces. Whether it’s a delicate prong setting or a thick shank, we handle every piece with the respect it deserves. Resizing often involves soldering and reworking the custom jewelry without disturbing its integrity. We also inspect the center stone, clasp, and structure to ensure everything remains secure. The Adam Foster Fine Jewelry Experience At our St. Louis jewelry store, we believe that every piece of jewelry tells a story. That story should begin with a perfect fit. From the elegance of lab-grown diamonds to the timeless charm of heirlooms passed down through generations, we tailor every step to you. If you're unsure where to start, or if you’re helping someone else measure their finger size, we're here to guide you. And if the ring doesn’t fit just right? Come see us for an expert ring sizing consultation. We’ll make sure your engagement ring, wedding band, or custom creation is not just beautiful, but beautifully worn. Stop by our intimate studio! Appointments are encouraged, but walk-ins are always welcome! Contact us today.

Lab-grown diamonds are changing the way people think about engagement rings and fine jewelry. These stunning stones offer all the brilliance, durability, and emotional impact of natural diamonds — with the added benefits of accessibility, sustainability, and transparency. At Adam Foster Fine Jewelry, we offer a wide variety of high-quality laboratory-grown diamonds in both classic and unique shapes, ideal for everything from timeless solitaires to more unconventional designs. If you’re considering a lab-grown diamond for your engagement ring or custom piece, this guide will help you understand the process, benefits, and how they compare to their natural counterparts. What Are Lab-Grown Diamonds? Also known as man-made diamonds, synthetic diamonds, or cultured diamonds, lab-grown diamonds are real diamonds that are created in a laboratory environment rather than mined from the earth. Unlike diamond simulants such as moissanite or cubic zirconia, lab-grown diamonds share the same physical properties, chemical composition, and crystal structure as natural diamonds. Lab-created diamonds are formed using two main methods: CVD (Chemical Vapor Deposition): In this method, a diamond seed (a sliver of pure carbon) is placed in a chamber filled with carbon-rich gas. Using heat and energy, carbon atoms adhere to the seed layer by layer, forming a diamond crystal. HPHT (High Pressure High Temperature): This mimics the pressure and temperature conditions found in the earth’s mantle, producing a rough diamond under controlled environment conditions.   Both methods create diamonds that are chemically and optically identical to mined diamonds, with no differences detectable to the naked eye. Are Lab-Grown Diamonds Real Diamonds? Yes, lab-grown diamonds are real diamonds. According to the Federal Trade Commission (FTC) and leading gemological institutes like the Gemological Institute of America (GIA) and International Gemological Institute (IGI), lab-created diamonds are indistinguishable from their natural counterparts in terms of composition and durability. They are graded on the same scale and criteria as mined diamonds: cut, color, clarity (which may include natural inclusions), and carat weight. Every lab-grown diamond we carry is hand-selected by our expert gemologists and comes with a diamond certification for complete confidence in quality. Benefits of Lab-Grown Diamonds Choosing a lab-grown diamond means choosing a forward-thinking and ethical approach to diamond jewelry. Some of the most popular reasons our clients choose laboratory-grown diamonds include: Sustainability: Lab diamonds are created using renewable energy and reduce the environmental impact associated with traditional diamond mining. Accessibility: You can often get a larger carat weight or higher quality diamond for the same price point as a smaller natural diamond. Conflict-Free: Lab diamonds offer peace of mind in knowing your stone is responsibly sourced and ethically created.

Steps to a Meaningful and Confident Decision Shopping for an engagement ring should feel exciting, not overwhelming. Whether you’re starting from scratch or have a vision in mind, our experienced team of jewelers is here to help you navigate every step — from choosing a diamond shape to finalizing a custom engagement ring design that feels just right for your partner and your story. At Adam Foster Fine Jewelry, we believe the perfect engagement ring is one that balances beauty, craftsmanship, and personal style. Below, you’ll find thoughtful tips and FAQs to help you begin your journey with clarity and confidence. Step 1. Set a Comfortable Budget There’s no one-size-fits-all formula, but having a general budget or range helps focus your engagement ring shopping experience. Some still follow the “two to three months' salary” tradition, while others simply set a price tag based on what feels right. We work within all budgets and will help you explore beautiful options, whether you’re considering natural diamonds, lab-grown diamonds, moissanite, or colored gemstones like sapphires or rubies. Step 2. Choose Your Center Stone The center stone is often the focal point of a diamond engagement ring. Our jewelers will help you compare options, including natural diamonds, lab-grown diamonds, moissanite, and even colored gemstones. We'll walk you through the 4Cs, including diamond cut, color, clarity (inclusions), and carat weight, so you can choose with confidence. Looking at loose stones in-store allows you to evaluate each one clearly and determine which works best with your selected ring setting. You’ll get a transparent look at the details that matter, especially if you're comparing GIA-certified stones. Popular diamond shapes include round brilliant, emerald cut, oval, and marquise. You may also want to explore three-stone or solitaire engagement ring styles — or halo and bezel setting designs that bring added visual interest. Step 3. Explore Engagement Ring Settings & Styles From delicate pavé bands to bold three-stone silhouettes, there are endless ring designs that can reflect your partner’s personal style. Do they love vintage details or clean, modern lines? Are they drawn to a classic round diamond, or something unexpected like an emerald cut or marquise center stone? We’ll help you pair your chosen center stone with a thoughtful setting. Whether that means selecting from best-selling engagement ring styles or creating a custom engagement ring, our jewelers are here to guide you. Settings are available in white gold, yellow gold, rose gold, and platinum, with each offering a unique look and feel. Step 4. Don’t Worry About Ring Size Not sure about your partner's ring size? You're not alone. Here are a few ways to estimate without giving anything away: Borrow a ring they wear on their ring finger and bring it into our jewelry store for measurement Ask a close family member or friend who might know their partner’s ring size Request a complimentary ring sizer from our showroom If the fit isn’t perfect, we offer complimentary resizing, often done within a day. Step 5. Think About the Future While the engagement ring takes center stage now, the wedding band will soon join the spotlight. It’s worth thinking ahead about how your selected design will pair with a wedding band. Some styles, like a solitaire or pavé setting, stack seamlessly. Others, like a dramatic halo or three-stone ring, may call for a custom band or bridal set. Also, consider if your piece of jewelry might include meaningful engraving, or if you’re interested in a matching ring for your significant other. Every detail — from prongs to metal finish — should feel intentional. Engagement Ring Shopping FAQs What is the difference between natural and lab-grown diamonds?Both are real diamonds with the same visual and chemical properties. The difference lies in origin — one is mined from the earth, the other created in a lab. Many clients opt for lab-grown diamonds for value and sustainability. What is the most durable engagement ring metal?All of our metals — white gold, yellow gold, rose gold, and platinum — are durable, but platinum offers the highest density and wear resistance. What engagement ring styles are trending right now?Solitaire, pavé, bezel setting, and hidden halo designs remain popular. Three-stone and vintage-inspired ring styles are also on the rise. Can I create a custom engagement ring?Yes! We specialize in custom engagement rings and can build a one-of-a-kind design around any stone, heirloom, or idea. Do your diamonds come with certification?Yes. We provide certification from respected grading institutions such as the Gemological Institute of America (GIA).
