*Specials


We serve as a Diamond Dealer and Broker between our cutter and you, the consumer. Located north of Pittsburgh in the Historic District of Old Wexford, we specialize in rare and exotic gemstones, loose diamonds and custom jewelry design. We are known for designing and creating one of a kind jewelry below retail prices. Most importantly we do all of our own work in our showroom.
Owner Charles Duffy started Diamond Design Jewelers 30 years ago Downtown in the Clark Building as a master craftsman for other jewelers in the Pittsburgh area. In 1991, after 10 years of being in business, Charles opened his showroom to the public and started what is now known as one of Pittsburgh's best kept secrets out in Wexford!
*We do not sell jewelry on our site because we firmly believe that jewelry is a purchase that should not be site unseen. The quality of a piece can only be evaluated in person.
