Setting consists in attaching a precious stone or gem to a metal mount by moving part of the metal. The techniques commonly used for settings include:
Prong/claw Setting
The prongs are tiny pieces of metal from the mount that the setter folds over the stone’s girdle securing the stone into place. This is the most common technique for solitary gems.
Bezel Setting
A tiny precious metal disk surrounds the stone. The sheet is folded over the entire perimeter of the stone securing it from the underside.
