Bi-Color Quartz

Bi-color Quartz from Brazil. This material is treated. It is smokey quartz somehow treated to turn half of it into citrine. The Brazilians will not reveal the process, but it is probably heat. The secret is how to get the zoning. Eventually it should be discovered.

Bi-Color Quartz from Brazil Bicolor Quartz is not normally found in nature. It is either Citrine or Smokey Quartz that is heated in such a way as to form the zoning seen here. The process is undisclosed at this time. Still, Emeralds are oiled, Sapphires are heated and some Tourmalines are heated or irradiated. So I suppose this is acceptable to some. Good looking stuff anyway.
