Physical properties
Hardness: 7 on Mohs scale; Color: Purple and white V-shaped bands; Luster: Vitreous; Crystal Structure: Hexagonal; Cleavage: None; Specific Gravity: 2.65
Formation & geological history
Formed through a combination of amethyst and white quartz in hydrothermal veins. The chevron pattern is created as layers of quartz grow inside a cavity, with the purple color resulting from irradiation of iron impurities.
Uses & applications
Commonly used in jewelry (cabochons), ornamental carvings, meditation stones, and as metaphysical specimens.
Geological facts
Chevron Amethyst is often called 'Dream Amethyst.' It is a combination of amethyst and white milky quartz that creates a distinct 'zigzag' or 'V' pattern, hence the name 'Chevron.'
Field identification & locations
Identifiable by the distinct alternating V-shaped bands of purple amethyst and white quartz. It is commonly found in Brazil, Russia, and India. Collectors should look for sharp color contrast and well-defined banding.
