Prong setting

Merged content from Tiffany mount to here. See Talk:Prong setting#Merger proposal.

Prong setting or prong mount refers to the use of metal projections or tines, called prongs, to secure a gemstone to a piece of jewelry. A prong setting is one component of what is known to jewelers as a head, a claw-shaped type of binding (typically 3, 4, or 6 individual prongs per head) that is welded or soldered to a jewelry item in order to mount (or set) a gemstone to the jewelry item. A common setting for diamond engagement rings, the prong setting allows light to strike a gemstone from more angles, increasing its brilliance.
