Presently diamond manufacturing is a mix of modern technology and traditional processes. While planning uses scanning technology and computer software to optimize the value of a finished diamond, much of polishing and faceting is still done as it have been for decades.
Planning has made great advances in the last decade. Technology and software have taken the guesswork out of the mapping function. Mapping can now detect inclusions (minor imperfections) inside a rough stone. Planning can propose sawing and polishing options to either include or exclude these inclusions. The goal is to reduce risk and maximize yield.
