The process of cutting and polishing gems is called Gemcutting or Lapidary, while a person who cuts and polishes gems is called a Gemcutter or a Lapidary (sometimes lapidarist).
Gemstone 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.
