Abstract
A prong setting for a ring or other jewelry item is provided. The prong setting is mounted along the jewelry item and includes one or more first prong elements and one or more facing second prong elements for defining an opening therebetween in which a jewelry stone is received. Preferably, each prong element includes a wire or lip portion for selectively engaging the jewelry stone. The wire portion is specially sized and shaped to enhance the strength of the setting in holding the stone therewith. In one embodiment, the prong elements are movable with respect to one another in order to be able to selectively adjust the distance between the prong elements, and thus the size of the opening. As a result, the prong setting can accommodate jewelry stones of varying size.
