T he process of cutting and polishing gems is called gemcutting. G emstone material that has not been extensively cut and polished is referred to generally as rough. Rough material that has been lightly hammered to knock off brittle, fractured material is said to have been cobbed. Rough corundum. A ll gems are cut and polished by progressive abrasion using finer and finer grits of harder substances. Diamond, the hardest naturally occurring substance, has a Mohs hardness of 10 and is used as an abrasive to cut and polish a wide variety of materials, including diamond itself.
The cabachon (flat on the bottom and rounded on the top) is the oldest and the most common cut I use. Some stones (such as opals) only come as cabachons. Cabachons come in round, oval, square, triangular, and even octagonal cuts. The height of the dome varies. The round brilliant cut is the most popular faceted cut for most stones, including diamonds. This cut refracts the most light, although it may sometimes, depending on the particular stone, not be the cut the lapidarist (stone cutter) uses. The oval cut is a modification of the round brilliant cut.
