ABSTRACT:
A rigid bar (or segment) on which stones will be at least partially supported is positioned in a rubber mold for creating a wax pattern of the jewelry, injecting wax to form a wax model of the jewelry including the metal bar to fit into an incision in the stones. The model with the metal bar forms the invisible pre-set stone mount. Stones are then placed into set position in the wax pattern on opposite sides of the metal bar. Once the setting is complete, the jewelry is created using known "lost-wax" method of manufacturing jewelry.
