Engagement & Bridal

At Adam Foster Fine Jewelry, we believe every piece of jewelry should tell a story. Whether you're proposing to the one you love, celebrating a milestone, or simply looking to treat yourself to something meaningful, we invite you to experience a different kind of jewelry store. One that puts relationships, craftsmanship, and your comfort with the entire experience first.

From timeless wedding bands to custom-designed engagement rings, we specialize in creating one-of-a-kind pieces handcrafted in our St. Louis studio by a team of jewelry consultants, bench workers, and Adam Foster, himself.

Custom Jewelry That Feels Personal

We’ve spent more than 20 years helping clients in St. Louis bring their custom jewelry ideas to life.

Passion drives everything Adam and his team do, from reimagining heirloom pieces to designing wedding rings, diamond jewelry, and everyday earrings, bracelets, and pendants. We work with all metals and stones, such as yellow gold, white gold, natural diamonds, lab-grown diamonds, colored gemstones, and more. We’ll even work with stones you already own!

And because everything is made in-house, there’s no middleman, which means more value and more control over the finished product.

What Our Clients Say

We love hearing from our customers! You’re the reason we’re here and the reason we do what we do.

Mickey Vande Voorde

Adam Foster is an incredible place to design custom jewelry. My partner and I worked with Danielle to design our engagement ring and we couldn’t be happier! She walked us through the whole process, offering plenty of combinations of stones and settings. We really appreciated the guidance she provided, while allowing our own opinions and desires to shine through. And the final product is amazing, highlighting the beauty of the stones we picked out with Danielle. Would definitely recommend Adam Foster for those looking for a custom and locally made engagement ring!

I contacted Adam about a ring he designed in 2016 that I fell in love with. I wasn’t able to get the ring at the time. I saved pictures and would often think about the ring. I reached out to Adam recently to see if he would recreate the ring for me. Mary responded to my inquiry email and about a month later I have my beautiful ring. Adam and Mary are so easy to work with. The ring is exactly like the one he created when I saw it.I would trust Adam to make any custom piece you may be thinking of. Mary is wonderful and responds quickly to answer any questions and assist in getting information to you. Great customer service and craftsmanship.

I have become a loyal admirer and customer of Adam Foster and cannot praise he and his partner Mary enough! I have bought many of his original designs which I get compliments on whenever I wear them! Especially my moonstone ring. He has even done a beautiful job on the custom earings and bracelet, which was my first custom piece. He has revolutionized jewelry shopping with his gorgeous stocked bar and accessible displays. His creativity and ideas have now made him my exclusive jeweler. I even have a multicolored pearl necklace he is redesigning as well as an Australian opal I just acquired. I have a long list of his pieces on my wish list including his XO collection, constellation pieces and want to add a turquoise piece to my collection as well. Adam and Mary are both so lovely, investing in their jewelry has become so much fun I can't stay away! Kristen Stout
