Diamond cutting is a task for human beings. The cutting must be carried out by a perfectly trained specialist, because – no matter how flawless the gemstones may be – an incorrectly placed cut will ruin everything. The sorting of the stones according to size, however, is done by machines. Much depends on them, too: the sorting process has to be very fast, yet there must not be any scratches. A sorting system with fast-switching valves manages to sort up to 10,000 diamonds per hour according to size without scratches.
