Abstract: A jewelry setting is provided to accommodate different shapes and sizes of gemstones. The multi-part jewelry setting comprises a gemstone holding means and a housing means for totally encasing a gemstone while affording substantial exposure of the gemstone. The U-shaped holding means is formed with a retaining means for engaging a peripheral edge of a gemstone and is formed to be resilient to accommodate gemstones of various diameters. By forming the gemstone holding means with a resilient material, the gemstone holding means will act like a spring and capture the gemstone by a compression fit. All of the components can be stamped from a single piece of sheet material. Being formed from sheet material, the completed housing is essentially hollow and results in an aesthetically pleasing, relatively inexpensive setting since less precious metal is required, even though, it appears to be of significant and massive precious metal construction.

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.

Abstract: A preform mold space is formed by two mold sections spaced from each other. A gem is positioned in the mold space, and a hardenable preform wax-like material is introduced into the mold space and into supporting contact with the gem to thereby form a preform model upon hardening of the wax-like material. The preform model is removed from the mold space and embedded in hardenable embedding material so as to form a mold cavity about the exterior of the preform model upon hardening of the embedding material. Simultaneously with the hardening process the wax-like material is melted and removed from the mold cavity while the gem remains embedded in the mold. A heated molten hardenable metal material is then introduced into the mold cavity. The hardened metal material supportingly engages different facets of the gem and fixedly anchors the latter in the article of jewelry formed by the disclosed method.
