Amethyst Stalactite Slices are very rare and they are only found in Uruguay. Slices are cut and polished from columns of amethyst ( stalactites) that developed millions of years ago inside amethyst geodes.
Amethyst geodes started as gas pockets in hot boiling lava where fluid silica and iron particles found their way inside to give the Amethyst it's purple colour. When the lava cooled off, the silica trapped inside formed the quartz crystals. 50 million years or so later, amethyst geodes are now mined from very hard lava basalt.
