Abstract:
Substantially hollow jewelry items made from metals, particularly precious metals, can be produced galvanoplastically, in that the metal is electrolytically deposited on an electrically conductive mould core having the spatial contour of the jewelry item, after reaching the desired coating thickness the core is chemically or thermally dissolved and the core material removed through an opening in the metal coating. In order to be able to provide such jewelry items with stones, particularly gems or semiprecious stones, the mould core is provided in the vicinity of the gem mount with a mould surface forming the gem support and nose, web or ring-like projections surrounding the same and that after removing the core material the gem is placed on the gem support and the mount parts formed by the projections are pressed onto the gem.
