  • Patent number: 5377506
    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.
