Physical properties
Hardness of 7 on the Mohs scale, transparent to translucent color with metallic flecks, vitreous luster, hexagonal crystal system, and conchoidal fracture.
Formation & geological history
Formed through hydrothermal veins where silica-rich fluids crystallized with iron sulfide over millions of years.
Uses & applications
Used in gemstone collection, metaphysical practices, and decorative jewelry.
Geological facts
Pyrite inclusions inside clear quartz are sometimes colloquially referred to as 'cat's gold' or 'healer's gold' due to their shimmering appearance.
Field identification & locations
Easily identified by its high hardness, glassy luster, and visible golden metallic flecks trapped within the matrix. Found globally in hydrothermal environments.
