Abstract
A method of imparting flat facets on hollow chain links intertwined to form a jewelry chain by tightly winding said jewelry chain about a drum of an ice lathe. Then freezing said drum and rotating it with said jewelry chain, next spraying water on said rotating chain in a controlled manner, to freeze at least part of each link of the chain in ice, and finally applying force by means of a pressure roller against at least one of said links of said chain, thereby at least partially flattening the outer wall of said at least one link to form a facet. After melting the ice, the chain is removed from the drum.
