The Chrysoberyl cats 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 calledchatoyancy. The incident light is reflected in such a way that that a bright strip of light appears running perpendicular to the inclusions.
