Most crystal is grown in the end, the process requires a lot of growth saturated groundwater source of silica, at a temperature between 550-600 ℃, and the need is greater than atmospheric pressure two to three times the pressure, after a long period of time , it will become hexagonal column (hexagonalsystem) crystal.
