In making a typical modern bezel setting the bezel is shaped into the size and shape of the gem and then soldered into place on the metal of the jewelry. The prepared stone is then placed into the bezel and the metal is pressed down over the edges of stone, locking it into place.
A cabochon stone, a gemstone that is not faceted, usually relies on the shallow angle cut into the side of the stone which helps the metal to stay in place. With a clear faceted stone, such as a diamond, a shallow groove is cut into the bezel itself. The girdle or widest part of the gem stone is placed in the bezel, which is then pushed down over the girdle. The pressure of the bezel over the edge of the diamond keeps it in place.
Bezel settings for diamond rings are also called rub-over settings; they have a diamond completely surrounded by a precious metal band which fastens the diamond securely into place. Bezel settings use a type of elevated collar which wraps the rim of the diamond in a complete metal edging. This type of diamond rings setting is the most secure fastener for the stones. The bezel setting also protects the diamond better than other types of settings, such as the prong setting. A flush setting for diamond rings is a variation on the rub-over or bezel setting. In the flush setting, the stone is placed into an opening and affixed at the bottom of the stone. The top of the diamond is extended above the base.
