*Diamond cutting* is the practice of changing a diamond from a rough stone
into a faceted gem. Cutting diamond requires specialized knowledge, tools,
equipment, and techniques because of its extreme difficulty.

The first guild of diamond cutters and polishers (diamantaire) was formed
in 1375 in Nuremberg, Germany, and led to the development of various types
of '*cut'*. This has two meanings in relation to diamonds. The first is the
shape: square, oval, and so on. The second relates to the specific quality
of cut within the shape, and the quality and price will vary greatly based
on the cut quality. Since diamonds are very hard to cut, special
diamond-bladed edges are used to cut them. The first major development in
diamond cutting came with the "Point Cut" during the later half of the 14th
century: the Point Cut follows the natural shape of an octahedral rough
diamond crystal, eliminating some waste in the cutting process.

Diamond cutting, as well as overall processing, is concentrated in a few
cities around the world: while 80% of rough diamonds are handled in the
Antwerp diamond district in Belgium, more than 50% of processed diamonds
also pass through there. Ninety-two percent of diamond pieces are cut in
