This popular purple gem sparkles with a beauty that inspired the ancients to call it the "gem of fire." These purple tumbles are polished smooth and perfect for holding during meditation or times of stress. Amethyst is as powerful as it is striking, transmuting negative energy into love and boosting creativity, inner peace, motivation, and balance. Amethyst is thought to have a sobering effect and has been said to improve insomnia and tension headaches.
