ABSTRACT:
A process of forming a metal stampato jewelry piece includes stamping a sheet of metal to produce a hollow front section of a desired shape; stamping a sheet of metal to produce a back section including a ledge defining an opening, the ledge having an outer periphery substantially corresponding to an outer periphery of the front section; and soldering the front section and the back section together such that the ledge outer periphery and the front section outer periphery are substantially aligned. The ledge imparts durability and sufficient rigidity to the stampato pieces to enable joining of the pieces by pins.
