Amethyst is a beautiful tumbled stone, with a rich, royal purple coloring that seems to radiate from its depths out through its translucent surface. This, combined with the large bail set upon its top makes it a beautiful pendant when you string it on your favorite chain or cord. It is also known for being a stone of the mind, providing and improving psychic ability and otherwise helping to heal headaches and balance moods. Though each stone varies, they measure approximately 3/4" in diameter on average.
