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
