Pyrite In Quartz Gemstone & Information | Gemopedia by JTV | Gemopedia™

Pyrite In Quartz

One of the most unique quartz varieties is a gorgeous crystal quartz that has the mineral pyrite encapsulated within its confines. Small pyrite crystals seem to float weightlessly in this crystal formation, creating an extremely unique appearance.
