Custom Engagement Rings

Why CD Clark Diamonds?

CD Clark Diamonds & Design Studio has been San Antonio's hidden gem for over 30 years, originally founded by Chad D. Clark and now led by his wife Stephanie Clark (GIA certified in Diamonds & Diamond Grading) alongside their son Joshua Clark, a Graduate Gemologist and Master Designer with degrees from GIA and Air Force veteran. As a small family business, we offer full-service capabilities with custom design, in-house casting, repairs, and appraisals all completed by GIA accredited staff, while honoring military families with discounts on all custom jewelry.

Engagement rings are the heart of our business and we take pride in helping craft a ring that will represent your love story and last a lifetime. We have a large selection of engagement ring styles in stock at all times and can work with you to design a fully custom engagement ring as well.

Our 3D ring builder is the best of both worlds – you get to design a fully custom ring and we can have it ready for you in just a couple of weeks at a great price, fully customized around your center stone. Come visit our San Antonio showroom to design your custom engagement ring in person or start your journey online using our cutting-edge 3D Ring Builder. Once you have a design you like, schedule an appointment so we can discuss diamond options and finalize your design.
