Amethyst

Amethyst was once one of the five cardinal gems alongside diamond, ruby, sapphire, and emerald — until massive Brazilian deposits were discovered in the 19th century, dropping its commercial price dramatically while keeping its symbolic status intact. The Greek name a-methystos translates to not drunken: ancient Greeks believed amethyst protected the wearer from intoxication. They carved drinking cups from amethyst, believing that wine in such cups could not make them drunk. Greek mythology says the god Bacchus, angered by mortal disrespect, vowed to unleash tigers on the next human he encountered — only to find the maiden Amethyst on her way to worship Diana. Diana turned her into clear quartz to spare her; Bacchus, repentant, poured wine over the stone, dyeing it forever purple.

Amethyst is the stone of mental clarity, spiritual awareness, and the third eye. In Christian symbolism it represents bishops, who traditionally wore amethyst rings as a sign of pastoral authority. The English regalia includes multiple amethysts. In modern crystal healing, amethyst is associated with the crown chakra and is the most-recommended stone for meditation, dream work, and breaking addictions. Wearing amethyst is said to enhance intuition, calm anxiety, and promote restful sleep. The deepest purple amethyst — called Deep Russian or Siberian color — is the most valued; lighter lavender stones are called Rose de France.

The Delhi Sapphire — actually a magnificent amethyst — was looted from a Hindu temple during the Indian Mutiny of 1857. Its English owners reported a series of misfortunes that led one to write a letter (sealed inside the gem's box) warning future owners. The Empress of Uruguay is the world's largest amethyst geode at 11 feet tall. The Russian Imperial Crown contains multiple amethysts gifted to Catherine the Great, who reportedly owned amethysts the size of plums. The Tiffany & Co. amethyst-and-diamond necklace owned by Wallis Simpson sold at auction in 2010.

Amethyst is hardy (Mohs 7), suitable for daily wear, but can fade with prolonged UV exposure — keep amethyst rings out of direct sun for hours at a time. Heat treatment converts low-quality amethyst into yellow citrine; this is why most commercial citrine is actually heated amethyst. Clean with warm water and mild soap. Ultrasonic cleaners are safe for untreated amethyst but should be avoided for any treated material. Store separately from harder stones (diamond, sapphire, ruby) to prevent scratching.
