We Are Always Buying

Our buyers are experts in valuing diamonds with GIA certificates, or certificates from IGI, AGS, HRD or EGL. No certificate? No problem – we will grade the diamond according to Gemological Institute of America standards. We have several GIA Diamond Graduate gemologists on staff.

We also buy gold jewelry, scrap gold, fine Swiss watches, rings and silverware. Bring your items to one of our locations today to get a free purchase value offer for your items. If you sell, you leave with immediate payment.

Over the years, Diamond Exchange buyers have paid competitive market prices for fine diamonds, gold jewelry, estate jewelry, watches like Rolex, Cartier, Omega, Patek Philippe and other brand name jewelry. We also value sterling silverware. If you are not using it, sell it to Diamond Exchange USA.

With 40 years of service as the premier jewelry buyer and seller in the Maryland, Virginia and the D.C. area, we have earned our reputation based on integrity and the delivery of an enhanced experience for our customers. Graduate gemologists and our watch experts on staff allow for the most exact and fair transactions in buying and selling. Thanks for visiting Diamond Exchange.

Craig was amazing to work with. He helped me and my fiancée come up with the perfect ring for us, and really extra hard to ensure that I had my ring in time for my proposal. I would absolutely work with them again and recommend them to anyone looing for a ring or custom jewelry.

I brought in my wife’s single solitaire diamond ring to the Columbia branch. I showed Craig a picture of a enhancer ring I saw in a popular mall type jewelry store. I gave Craig a budget I had to work with. I described the shape I would like and the amount of diamonds involved. Craig sent out my wife’s ring to his Jewlers who made a 3D image of how it would look. Quality gold and diamonds were used, Craig and diamond exchange USA worked with me and kept it in my budget!! The two rings mated to each other and looks like one!! My wife is going to be totally surprised. I told her the jeweler was fixing her prong and and cleaning the ring up! Which isn’t a lie they threw that in to match the new ring!
Thank you Craig for all your help!!

I had some 14k gold items that I had collected over the years but never wore much. Craig was helpful and let me know which items weren't solid and other info about them. I wasn't looking for a lot for the items and I think the price I got was totally fair. I'm glad that someone else will probably enjoy them more than myself, or at least that they'll be recycled in some way. Thanks much 🙂
