Abstract

Gem settings for jewelry pieces made from noble metals for gems to be set over larger areas in coherent arrangement into large-top bodies wherein a plurality of small stones having a round top-view configuration, being of larger and relatively smaller diameters and having a downwardly extending pointed end and a sharp peripheral edge are disposed in the top of the metal jewelry piece body snugly side by side in funnel-shaped setting recesses whose coordinates have been exactly predetermined and which are disposed in relatively staggered longitudinal rows while leaving gaps of minimum size to provide the prongs needed for setting the larger-size stones, the recesses for the smaller gems being of greater depth so as to make the larger-size gems overlap the smaller stones after insertion. For stones having a round contour, the gem setting gives a 95% area coverage so that the impression of a fully coherent array of gems is created.

A gem setting for a jewelry piece made from noble metals for gems to be set over large areas into large-top bodies in a coherent arrangement in which a plurality of small stones having a round top-view configuration with a downwardly extending pointed end and a sharp peripheral edge are disposed in the top of the metal jewelry piece body snugly side by side, in which the pointed ends of the gems are each inserted into corresponding open-bottom funnel-shaped setting recesses milled into the solid metal of the piece body, and in which after insertion the gems are held by prongs or such like which have been formed intermediately of said funnel-shaped recesses, said setting being formed with the gem-receiving funnel-shaped recesses in primary longitudinal rows in the top of the piece body after precise measurements to determine the positions thereof while at the same time providing lateral spacings from the marginal edge of the piece and body with close relative spacings between said recesses wherein as viewed across the body those funnel-shaped recesses that are of identical size at least are arranged side by side such that centers thereof are precisely disposed along an imaginary connecting line extending at a right angle to a longitudinal centerline of the piece body;

an amount of residual metal being left as needed to provide prongs for setting larger-size stones, while a plurality of said funnel-shaped setting recesses receive gems of smaller volume are disposed each at points of intersection between the imaginary connecting lines for surrounding larger-size gems through which they extend, in a plurality of other rows staggered in relation to said primary rows, that they slightly overlap the recesses for said larger-size stones and are of greater depth than the recesses for the larger-size stones to thereby ensure that the larger-size stones partly overlap the adjacent stones of smaller size after insertion;
and said being swaged for setting the larger-size stones along their sharp peripheral edges on placement.
