Unlike most Internet jewelers, at Diamond Design Co. each piece of jewelry is carefully designed and crafted by our in-house jewelers.

Need it wider, smaller, more stones, less stones, a different metal or precious stone, NOT A PROBLEM. Our jewelry is made-to-order-, "made by us for you".

Fine quality jewelry should come with fine quality service

Our Vision

To commemorate your special occasions with jewelry made just for you. Using the latest design technology and the finest hand selected diamonds and gems, with quality comparable only to the finest jewelry retailers in the world.

Our Quality Commitment

At Diamond Design Co. we are committed to Tiffany standards of fine quality jewelry. Our diamonds are hand selected and graded. Our jewelry is precision designed and manufactured, using the latest jewelry technology and we will not compromise our quality standards.

If you’ve ever been to Tiffany’s and seen a truly exquisite piece of fine jewelry, you have most likely been discouraged by your on-line shopping experience thus far. There are so many jewelry websites out there, most peddling the same low quality, mass produced, over priced jewelry. Even the “BIG 3” who are attempting to dominate the Internet, they too are just resellers that pass on their advertising and overhead costs to you. Sure you can have it overnight in a cardboard box. But will it be worth the dollar you paid for it, a year from now, five years from now? When the purchase of fine jewelry is for someone special, including yourself, forget the gimmicks and flashy websites, select fine quality jewelry that is uniquely made for you.

We use CAD design systems and integrating wax milling. Our jewelry is made by us for you. Learn more about How our jewelry is made.
