clear rock crystal 3kg, from Brazil
PUMI2013
Remarkable natural shape - twinning- of natural crystals from Brazil. this piece comes from Minas Gerais area, the place where most pure rock crystals come from. They are the result of a mixture of a solution of minerals (silicon and oxygen mainly) dissolved in very hot water -between 250 and 850 degrees celcius. And they formed underground more than 100 million years ago, miles deep. They arrived in their current position during the Cretaceous uplift, about 100 million years ago. The result is timeless and pure, on its black base.
