Earthy matte wild horse jasper beads offer swirls, spots, and bands predominantly in shades of brown, tan, and greenish-gray. These semiprecious beads are cut from rough found in Wild Horse Canyon in Oregon, USA. The gemstone is also known as wildhorse picture jasper, American picture jasper, and owyhee jasper. As with other true jaspers, wild horse jasper is an opaque, metamorphic rock containing microscopic "grains" of crystalline quartz. Jaspers have been popular since the ancient world. They are said to give the wearer courage to speak out and bravery to achieve personal independence.
