Claw setting is accomplished by cutting prongs into or soldering them to the outside of a collet or bezel. The stone sits on a metal band soldered inside the bezel and the prongs are pressed over the crown facets to keep the stone in place. The claw setting was developed in the 19th century to set transparent stones in such a way as to allow light to enter and pass through the stone that is exposed both top and bottom.
