Amethyst is one of the most useful stones. In our experience, when you don't know what stone a person needs, give them an amethyst - as it's one of the best stress relievers available. Amethyst also protects against psychic attacks, especially during spiritual work, and is a protection from thieves. Amethyst also protects travelers. Our polished Amethyst has been tumbled until the edges are smooth. 1 pound packet contains 30 to 40 stones.
