Physical properties

Hardness: 7 on Mohs scale; Color: V-shaped bands of purple and white; Luster: Vitreous; Crystal Structure: Trigonal/Hexagonal; Cleavage: None/Conchoidal fracture; Specific Gravity: 2.65

Formation & geological history

Formed in hydrothermal veins and cavities (geodes) where alternating layers of amethyst and milky quartz or white quartz crystallize during cooling; often found in Precambrian to Cretaceous basaltic host rocks

Uses & applications

Popularly used for lapidary work, decorative carvings, beads, spiritual gemstones, and entry-level geological collections

Geological facts

Also known as Dog-tooth Amethyst, it is one of the most powerful 'third eye' stones in metaphysical belief. Its distinctive patterns are caused by natural internal stresses during the quartz growth process.

Field identification & locations

Identify by a sharp, repeating 'V' or zigzag pattern of purple and white. Primarily sourced from Brazil, Zambia, South Africa, and India. It is easily distinguished from solid amethyst by its high-contrast banding.
