METHOD OF PRODUCING JEWELLERY AND OTHER PRECIOUS METAL PRODUCTS WITH COMPLEX GEOMETRIES

摘要

The present invention relates to a novel method of producing in one and the same operation precious hallmarked precious metal products. The method is particularly suited for production of such precious metal products, i.e. jewelry and objets d'art, which have complex geometries.
