Explore the Difference

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

Custom Design by Diamond Design Co.

Work with our Custom Design Department to build your dream ring.

At Diamond Design Co. we have invested in the latest 3D modeling technology, and would love to work with you to create the perfect ring with diamonds and gemstones you already have or we can provide. We use the most advanced technology in custom ring design in the industry. By sending us a drawing or a picture, our custom design department will bring it to life. After the design is finished and is approved by you, it will go into production immediately.

Most custom designs are created by hand, but are not perfect. With this advanced technology our diamond & gem designs are created using a 3D modeling program designed especially for jewelry.

When designing your creation, we design for actual stone sizes and shapes to insure excellent proportions and balance. View our video gallery to learn more. And see our photo gallery for ideas.

Quality & Value At It's Finest!

After a ring is designed with this technology, the parameters are sent to a SOLID PRINTER that creates the perfect model for casting. We specializes in platinum, but can cast your design in the metal of your choice. Working with our Custom Design Department you can approve every step in this process via pictures sent by e-mail. We are completely quality and client service driven and at any time during the design process you can make any changes you wish. Your ring is not cast until you approve it. Upon receiving your ring, if you are not completely satisfied, our 45-Day Safisfaction policy ensures you receive a full refund, excluding design fees quoted at time of order (avg. $150-250).

Please view our Custom Design Brochure for more information or call for your appointment today 1-866-488-3326.

The ring you create also comes with an appraisal from a GIA Diamond Graduate and all applicable diamond grade reports.
