Brilliant: The most popular style of cutting both diamonds and
colored stones. The standard round brilliant consists of 57
facets; 1 table, 8 bezel facets, 8 star facets and 16 upper-girdle
facets on the crown; and 8 pavilion facets, 16 lower girdle
facets; and usually a culet on the pavilion. Modifications of
the round brilliant include such fancy shapes as the marquise,
half moon, pear shape and many others.
