Tiger's Eye is both beautiful and unique in banding with a spectacular sheen that seems to originate from within and leap off the surface. Called chatoyancy, the remarkable appearance is due to quartz aggregate fibers that reflect light. This sphere is carved from natural stone and contains a higher level of iron than other Tigers Eye Spheres. It could be called Iron Tigers Eye.
