Physical properties
Hardness: 7 (Mohs scale), Color: Artificial bright purple-pink on white/clear crystals, Luster: Vitreous (glassy), Structure: Hexagonal crystals, Fracture: Conchoidal
Formation & geological history
Natural quartz formed in volcanic or sedimentary cavities over millions of years by silica-rich hydrothermal fluids; later industrially altered through dyeing processes.
Uses & applications
Used primarily as decorative items, souvenirs, curriculum aids for children, and in metaphysical gift shops.
Geological facts
While the geode structure and quartz crystals are natural, the vivid neon-purple color is achieved by soaking the specimen in dye. Real amethyst has a more uniform, internal color that is usually a softer violet rather than concentrated on the crystal edges.
Field identification & locations
Identify by looking for dye concentrations in cracks and unnatural color saturations. Real amethyst is generally light-stable, while dyed quartz can fade over time if left in direct sunlight. Commonly found in Morocco or Brazil.
