Rose-cut diamonds are seldom seen nowadays, except in antique and Art Deco jewelry. There have been various forms of the rose cuts since the mid-16th century which have been derived from older types of cuts. The basic rose cut has a flat base and has a crown composed of triangular facets (usually 12 or 24) rising to form a point in an arrangement with sixfold rotational symmetry. The double rose cut is a variation that adds six kite facets at the margin of the base. The classic rose cut is circular in outline. Reference: Wikipedia
