Pyrite In Quartz Medium

Pyrite quartz is a type of quartz crystal that forms in combination with pyrite. It is a combination of quartz, a silicon dioxide mineral, and pyrite, an iron sulfide mineral. The two minerals form together in a process called pseudomorphism, in which one mineral replaces another in its crystal structure and takes on its form. It is often used as a decorative stone in jewelry and for other decorative purposes.
