Physical properties
Hardness of 7 on the Mohs scale, color features distinct V-shaped bands of purple and white quartz, vitreous luster, trigonal crystal system, conchoidal fracture, specific gravity of 2.65.
Formation & geological history
Forms in hydrothermal veins or cavities within volcanic rocks where silica-rich fluids deposit quartz in alternating bands with white quartz.
Uses & applications
Commonly used in crystal healing, lapidary arts, jewelry, and as a decorative collector mineral.
Geological facts
The distinctive chevron or V-shaped banding is created by alternating layers of violet amethyst and white milky quartz growing together during formation.
Field identification & locations
Easily identified visually by its unique purple and white zig-zag or chevron patterns. Found worldwide, with significant deposits in Brazil, Madagascar, and South Africa.
