Abstract
A method of diamond cutting or faceting hollow link jewelry chain by arranging a chain on an ice lathe support, completely freezing the chain on such support and moving a blunt instrument across such chain to produce flattened links. The pressure of the blunt instrument against the frozen chain simultaneously scrapes off the ice and flattens the links, thereby avoiding the requirement that the portion of the links that are to be faceted be initially unfrozen. The blunt instrument may be a so-called 'finger of steel', which can be sharp, pointed, rounded, arcuate, smooth or the like. A variety of faceting formations can be realized depending on the movement of the blunt instrument across the outer surface of such chain.
