Amethyst is a purple variety of quartz (SiO₂) prized worldwide for its rich hues. With a Mohs hardness of 7, a refractive index of 1.544‑1.553, a birefringence of 0.009, and a specific gravity of 2.66, this crystal ranges from pale lavender to deep violet. The name comes from the Greek amethystos, meaning “not drunk,” reflecting an ancient belief that the stone prevented intoxication.
For centuries amethysts were valued alongside rubies and emeralds, until the 19th‑century discovery of large Brazilian deposits. Today, high‑quality specimens remain popular—and affordable—gemstones.
Globally, amethysts appear in veins and geodes within alluvial deposits. Major sources include Siberia, Zambia, Bolivia, Uruguay, Mexico, India, Namibia, Nigeria, Madagascar, South Korea, and Brazil.
In the United States, North Carolina and Georgia host accessible amethyst mines where enthusiasts can dig under guided supervision.
Crystal digging in Georgia is typically offered by private operators who open their fields to the public.
