The process of diamond cutting has been known in the Indian subcontinent as early as the sixth century AD. Different countries base their cut grading on different ideals: one may speak of the American Standard or the Scandinavian Standard ( Scan. The strictest standards are applied to the round brilliant although its facet count is invariable, its proportions are not. A diamond's cut is evaluated by trained graders, with higher grades given to stones whose symmetry and proportions most closely match the particular 'ideal' used as a benchmark. Also popular are the fancy cuts, which come in a variety of shapes, many of which were derived from the round brilliant. The most popular of diamond cuts is the modern round brilliant, whose facet arrangements and proportions have been perfected by both mathematical and empirical analysis. Design, creation and innovation continue to the present day: new technology-notably laser cutting and computer-aided design-has enabled the development of cuts whose complexity, optical performance, and waste reduction were hitherto unthinkable. The practical history of diamond cuts can be traced back to the Middle Ages, while their theoretical basis was not developed until the turn of the 20th century. Diamond cutters must consider several factors, such as the shape and size of the crystal, when choosing a cut. A diamond cut constitutes a more or less symmetrical arrangement of facets, which together modify the shape and appearance of a diamond crystal. In order to best use a diamond gemstone's material properties, a number of different diamond cuts have been developed. The cut of a diamond greatly affects a diamond's brilliance - a poorly-cut diamond is less luminous. Cut refers to shape (pear, oval), and also the symmetry, proportioning and polish of a diamond.

The rose cut is omitted, but it could be considered intermediate between the old single and Mazarin cuts.
