Physical properties

Hardness: 7 (Mohs scale); Color: Purple with white or gray V-shaped bands; Luster: Vitreous (glassy); Crystal structure: Hexagonal; Cleavage: None (conchoidal fracture); Specific gravity: 2.65

Formation & geological history

Formed through hydrothermal processes where silica-rich fluids deposit in volcanic or sedimentary cavities. The chevron pattern occurs as alternating layers of amethyst and white quartz grow over time due to changes in mineral concentration and temperature.

Uses & applications

Predominantly used for lapidary work, jewelry (cabs and beads), decorative carvings, and metaphysical collecting.

Geological facts

The 'Chevron' naming convention specifically refers to the white quartz banding that forms a 'V' or zigzag shape. It combines the properties of macrocrystalline quartz and amethyst in a single specimen.

Field identification & locations

Identify in the field by its distinct purple and white triangular banding. Commonly found in large deposits in Brazil, Uruguay, Africa, and India. It is a popular 'tumble stone' for beginners due to its high polish and durability.
