Raw Amethyst Cathedral Geode

A standing cathedral geode, sawn open and polished flat along one face to reveal a cavern lined wall to wall with deep violet amethyst points, some reaching several centimeters, catching light differently from every angle. It stands upright on its own cut base without need of a stand, a small chapel of stone weighing between 2.4 and 3.1 kilograms — heavier in the hand than its size suggests, the walls thick and the crystal growth dense throughout. Amethyst takes its name from the Greek amethystos, "not drunk," after a belief that wine drunk from an amethyst cup would not intoxicate its drinker. The Greeks carved wine vessels from it on that premise, and centuries later bishops set it into rings as a stone of clarity and sober judgment, its color long associated with temperance and calm thought rather than excess. Set upright on a shelf, mantel, or desk where daylight or lamplight can cross the crystal faces and catch their color; no cleansing or upkeep is required beyond the occasional dusting of the outer rock. Each geode is a single, unrepeatable specimen from Rio Grande do Sul, and the piece photographed is the exact piece that ships. Sold as a curiosity — no medical or scientific claims are made.
