Amethyst is a beautiful purple variety of quartz, prized historically and in modern times for its color and supposed properties. It ranges in hue from light pinkish to deep purple. The color comes from trace amounts of iron and aluminum, with its exact shade determined by the presence and concentration of these elements, plus exposure to natural radiation.

Historically, amethyst was as valuable as rubies and emeralds. Ancient Greeks and Romans wore it believing it prevented intoxication. The name "amethyst" comes from the Greek word "amethystos," meaning "not drunken." Amethysts were often carved into drinking vessels to ward off intoxication.

Amethyst is often associated with spirituality and healing. It's thought to help with clarity of the mind and heightened intuition. It's frequently used in meditation practices and is said to aid in promoting calm and balance.

Amethysts are found worldwide, with significant deposits in Brazil, Uruguay, Russia, and Zambia. Brazilian and Uruguayan amethysts are particularly famed for their size and quality. Amethyst crystals can form as huge geodes, sometimes large enough to stand inside, called "cathedrals" due to their arch-like shapes.

In terms of care, amethyst ranks 7 on the Mohs hardness scale, meaning it’s reasonably durable but can be scratched by materials harder than itself. Prolonged exposure to light can cause its vibrant color to fade.

Whether you're drawn to it for its beauty or its historical and supposed metaphysical properties, amethyst remains a beloved gemstone across cultures and ages.
