Custom Jewelry
At Adam Foster Fine Jewelry, we believe that jewelry should never be ordinary. That’s why we create every custom piece in-house, by hand, using a process that’s as personal as the piece itself.
From delicate earrings and necklaces to engagement rings and heirloom redesigns, our team of artists and bench jewelers brings each idea to life with care, precision, and a deep respect for craftsmanship. We use time-honored techniques alongside modern technology to create something entirely unique.
Whether you arrive with a vision or a blank slate, we’re here to make the process simple. After all, our passion is helping you make something meaningful.
Discover the art of custom jewelry design where every piece is crafted with care and precision—just like our stunning engagement rings and necklaces that reflect your unique story.
Bring Us What Matters Most
We are one of the only places in St. Louis where you can bring in your own stone, charm, or family keepsake, and we will create something new!
Whether it's a diamond from a past generation or even a metal dog tag that tells a story, we’ll treat it with the care it deserves. Together, we’ll design around it and build something lasting.
You bring the meaning. We bring the hands that shape it.
A Collaboration Between Maker and Muse
Designing custom jewelry isn’t about perfection. It’s about connection. Each conversation, sketch, and decision is part of the journey. You’ll work directly with our team to choose your materials, refine your design, and follow the progress as your piece moves from concept to finished treasure.
Our clients often tell us that being part of the creative process is their favorite part!
The Custom Design Process
Our process is deeply personal. It's not about templates, because we design with intention and offer the kind of precision only possible when everything is made in-house, by makers who care.
Let’s Talk
Meet in person at our Saint Louis showroom or begin the conversation virtually. Bring your vision, your questions, and any inspiration, such as a picture or even a hand-drawn sketch. We’ll take time to understand what you want!
Design & Details
We explore options together, from metal color to stone type.
CAD & Review
Next, we turn your idea into a CAD rendering. This is where you’ll see your custom piece come to life, and you’ll have the chance to make changes before we begin production.
Handcrafted In-House
Your piece is crafted entirely in our St. Louis studio by our in-house bench jewelers with precise attention to detail. This is where Old-World technique meets New-World technology! We’ll keep you updated throughout the process, so you can feel confident at every step.
The Reveal
The finished piece is yours to try on, admire, and treasure. Sizing, warranty, and documentation (including GIA certifications for diamonds) are all handled with care.
