My husband and I have been buying jewelry from Moishe of MDC Diamonds NYC since 2013. MDC Diamonds (and Moishe) is the only place I trust and will shop for diamonds period. But MDC Diamonds does so much more then just sell diamonds. They will customize a piece of jewelry that you see at Tiffany's or Winston's for substantially less or collaborate with you to design a one-of-a-kind piece of jewelry. At MDC Diamonds you have the ability to pick out the stones you want or you can do what I do - give Moishe your budget and he pick the most gorgeous stones to match it. I cannot say enough about MDC Diamonds. MDC designed my engagement and wedding bands, stunning diamond loop earrings along with several other pieces. Below is my newest piece!
