I've listed power stones before, but this time I'm creating various ones to be attached to the main amulets I'm selling... If you find one you like, please attach it to your main amulet. Purple Cat's Eye 10mm This stone is said to ward off evil, help you see the true nature of things, and discern lies and deceit, giving you the power to make accurate judgments. It comes in a variety of colors and shapes, which makes choosing fun and can also reduce stress.
