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, [2] eliminating some waste in the cutting process. Diamond cutting, as well as overall processing, is concentrated in a few cities around the world.

The rough, therefore, needs to be extensively studied so it can be positioned for optimal cutting on the machine. The machines must be more durable and have different features than cutting machines for other gemstones. The process is far more involved and, of course, more expensive, so diamond cutting hobbyists are far rarer than cutters of ...

The diamond cutting process relies heavily on this directional hardness, as without it a diamond would be nearly impossible to fashion. Cleavage also plays a helpful role, especially in large stones where the cutter wishes to remove flawed material or to produce more than one stone from the same piece of rough (e.g. Cullinan Diamond).
