Physical properties

Hardness of 7 on the Mohs scale; purple and white banded color; vitreous luster; hexagonal crystal system; no cleavage; specific gravity of 2.65

Formation & geological history

Forms in hydrothermal veins or cavities in volcanic rocks where silica-rich fluids cool and precipitate quartz crystals with alternating layers of white quartz and purple amethyst, often over millions of years.

Uses & applications

Used in jewelry, ornamental carvings, crystal healing, and as a collectible mineral specimen.

Geological facts

Chevron amethyst combines the magnifying and strengthening properties of white quartz with the stress-relieving properties of amethyst, creating a distinct V-shaped or striped pattern.

Field identification & locations

Easily identified in the field by its distinct chevron (V-shaped) or striped purple and white banding. Commonly found in Brazil, Madagascar, South Africa, and the USA.
