Diamonds and Custom Jewelry
Stunningly Affordable™
Design Your Own Jewelry
DC/PDC offers its clientele a studio, not a store.
ADC/PDC is a custom jewelry studio known for unique bridal jewelry designs, quality certified diamonds, and knowledgeable Graduate Gemologists. We have beautiful pieces to view but most of our custom jewelry begins with a sketch, where designers lend advice and help inspire the perfect piece. In the studio we show loose and raw gemstones, compare noble metals like gold and platinum and offer examples of the kind of craftsmanship that makes all of our stores a destination for custom engagement and wedding bands. We look forward to working with you to create something special made with responsibly sourced diamonds including non-mined diamonds™ that are are created using the same chemical composition of a natural diamond.

Why Shop At PDC

It’s often assumed that custom jewelry costs more than mass produced. However, by doing all our work in-house and selling direct to our clients, our bespoke custom pieces are often less expensive that branded designer lines.
