This Chelsea jewelry boutique specializes in custom designs for men and women. Its non-custom inventory is fascinating and unique, too: check out George Sawyer’s mokume gane wedding bands and engagement rings, for example. (Mokume gane is a Japanese technique in which metal is folded to appear like wood grain). There’s also the handmade filigree of Tibor Marcus and intricate pieces by Alex Sepkus that recall the architectural details of a medieval church. For a more minimal turn, DVVS offers its own line of pared-down bands and necklaces.
