The outer rim of a bezel is burnished, or bent over and smoothed out around the girdle of a gemstone. A bezel setting is an extremely secure one. Sometimes, a white gold bezel can actually make a diamond look larger because the color of the metal blends with the diamond.

The term refers to the shape of the gemstone, not quality or actual brilliance. There are 16 upper girdle facets, 8 Star facets, 8 Bezel facets, and a table facet above the girdle.

CAMEO A shell or other gemstone that is carved in relief. When the material to be carved is composed of two different colored layers, a raised design in one color will contrast against a different colored background.
CARAT A very accurate unit of weight used for gemstones. The word carat is derived from the carob seed, which was used in the days of antiquity as counterweights on scales for small measurements because Carob seeds were extremely similar in weight. A carat is equal to 1/5th of a gram, or (200) milligrams, and there are about 140 Carats in 1 ounce. The word “Karat”, which is used to describe the content of fine gold in an alloy is often confused with “Carat”, the unit of weight.
