Amethyst is a purple variety of quartz (SiO2) that forms as well-formed prismatic crystals often in geodes or nodular masses. Its color ranges from pale lilac to deep violet, typically resulting from trace iron impurities and irradiation. Crystals commonly exhibit vitreous to resinous luster and can display zoning or phantom effects within clear to purple interiors.

Significant localities include Mexico, Brazil, the USA, Namibia, and India, where geodes and vein deposits yield well-terminated crystals and sizable specimens.
