About Us

We are Diamond Design Jewelers of Wexford

Since 1979 we have specialized in rare and exotic gemstones, loose diamonds and jewelry design. Owner, Charles Duffy, started Diamond Designs in downtown Pittsburgh in the Clark Building as a master craftsman for other jewelers in the Pittsburgh area. In 1991 we opened our showroom to the public and in 1996 we moved our store to Wexford in Pittsburgh's North Hills.  We are known for designing and creating one of a kind jewelry through the latest trends in technology. Most of our design work is done through CAD design and 3D printing.
