This popular purple gem sparkles with a beauty that inspired the ancients to call it the "gem of fire." This big juicy amethyst slab has a polished back and showcases the signature purple color with pure white calcite. Amethyst is as powerful as it is striking, transmuting negative energy into love and boosting creativity, inner peace, motivation, and balance.
