Abstract: Pink colored metal alloys have a low gold content. The pink colored metal alloys of the present disclosure display a high level of tarnish resistance during extended use and wear, and have the appearance and properties comparable 10 karat (or above) gold alloys, which have a significantly higher gold content.
Abstract: A gem setting for gemstones includes a channel with walls having grooves for holding a portion of a gem girdle, such that when a gem having a crown is set into the channel, the upper portion of the groove extends over the crown of the gem. The upper part of the channel above the groove can be permanently bent or rolled over the crown of the gem to secure the gem in the ring channel. A method of setting a gem in the channel includes inserting the gem girdle in the grooves, without permanently bending the channel walls, until the gem is positioned within the channel such that if the gem and ring together are placed in an upside down position, the gem will not fall out of the channel. Next, the upper part of each channel is permanently bent over the crown of the gem, to thereby secure the gem in the channel.

Abstract: A setting and a method of making a setting include a V-end prong member having two V-shaped prongs preferably fabricated from a single length of material such as, for example, a round wire. Two grooves are die-struck into the length of material and extend from a center portion of the length of material toward opposite ends thereof. The length of material is blanked so as to trim excess material therefrom, forming a blank having opposite, receptacle-defining end portions, and a central portion. The blank is then bent so that the receptacles face each other to define the V-end prong member having two V-shaped end prongs and a central portion. A conventional prong member can then be attached to the central portion of the V-end prong member. The prong member includes spaced distal ends that confine the article between the spaced distal ends and the receptacles.

Abstract: A gem setting includes a base and prongs. Each of the prongs has a notch shaped for holding a portion of a gem girdle, such that when a gem having a crown is set into the setting, the upper portion of the notch extends over the crown of the gem. Each prong also has an upper part above the notch, which may be permanently bent over the crown of the gem to secure the gem in the setting. A method of setting a gem in the setting includes stabilizing the gem at a fixed location, and then moving the gem and setting together, without permanently bending the prongs, until the gem positioned within the setting such that, if the gem and setting together are placed in an upside down position, the gem will not fall out of the setting. Next, the upper part of each prong is permanently bent over the crown of the gem, to thereby secure the gem in the setting.
