Hydrothermal Quartz Stones  

Hydrothermal Quartz is grown in a hydrothermal process and moderate temperature but very high pressure. The process uses a thick pressure vessel able to with-stand the high pressure. Hydrothermal Quartz stones are also known as the Synthetic stones as it is the closest mankind has got to immitating the natural quartz. The hydrothermal quartz we supply here has the same chemical properties as the real amethyst.
