Abstract
This invention relates to processes for making jewelry comprising one or more rows of precious stones set in a support made of precious metal. One or more rows of cylindrical housings extended by a conical seating and a counter-bore are machined in the support; the metal bridges separating, the housings are cut out with a rotating mill; a stone is placed in each housing and is set by means of a tool which is applied on the islets of metal remaining between the housings.
Claims10
A process for making jewelry comprising one or more rows of stones set in a support made of precious metal, said process comprising the following steps:
- machining said support to form one or more rows of cylindrical housings comprising an outer bore, a conical seating and a counter-bore the housing being separated by metal bridges of at least two thicknesses;
- cutting, with a rotating mill the thinner part of the metal bridges which separate juxtaposed outer bores over a height equal to that of said outer bores with the result that each outer bore remains surrounded by islets of metal, uniformly distributed over its periphery;
- placing a stone in each housing;
- said stone abutting on said conical seating;
- and setting said stone by means of a concave-headed tool, which is applied axially on said islets to deform them permanently by buckling.
