The mining and extraction of gemstones have a long history. Even in the Stone Age, flintstone was a "gemstone" for people that was not only collected, but mined in an organized way. Of course, in recent centuries, mechanization has not stopped at gemstone mining, yet surprisingly little has changed in the basic way of extracting gemstones.
