The Chrysoberyl cat’s eye is a miracle of Nature! This gem has a thin Bright Silver band of light on a shimmering golden background, and glides across the surface.

Fine inclusions in the stone are responsible for this phenomenon called chatoyancy. The incident light is reflected in such a way that that a bright strip of light appears running perpendicular to the inclusions.
