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.
