Physical properties
Hardness of 7 on the Mohs scale, consisting of purple amethyst and white quartz in a V-shaped or chevron pattern. Vitreous luster, hexagonal crystal structure (though often found massive with banding), no cleavage, specific gravity of 2.65.
Formation & geological history
Formed in hydrothermal veins and cavities within igneous rocks where silica-rich fluids deposit layers of quartz and amethyst over time.
Uses & applications
Commonly used in jewelry making, ornamental carvings, and as a popular specimen for collectors and metaphysical practitioners.
Geological facts
The distinct V-shaped or zigzag pattern is what gives Chevron Amethyst its name. It is also sometimes known as 'Dogtooth Amethyst'.
Field identification & locations
Easily identified by its alternating purple and white V-shaped bands. It is commonly found in countries like Brazil, India, and parts of Africa.
