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.
