This striking gemstone cabochon is known as a cat's eye
green tourmaline. Under a point light source, this gem exhibits a band
of light which moves as the gemstone is moved. Long, parallel, microscopic
cavities are responsible for this effect. The stronger and more singular
the light source, the sharper the cat's eye effect. You should see this
stone in sunlight. This gem is 11 millimeters in diameter, and weighs 7.5 carats. It is priced at $50.00 per carat, $375.00 for the stone.
