Processing In small operations gem stone ores are broken crushed and concentrated by hand picking washing screening or jigging In larger operations mechanized processes are employed
The mining techniques adopted to extract gemstones invariably reflect the nature of the deposit primary deposits in hard rocks worked underground or in open pits and secondary deposits found in sedimentary softrock placers The mineralogy of a gem dictates the type of geological environment in which it can be found
Environmental impacts of mining largely depend on the methods used and the geological context that governs how easily the minerals can be separated from the ore material Unlike gold mining which often uses potentially toxic chemicals such as mercury and cyanide gemstone mining does not depend on chemicals for extraction of the rough material
