Gemstone Glossary

Traditionally, Cat's Eye is an expensive form of Chrysoberyl. It occurs in a cloudy yellow to brownish-green color, with varying hues and excellent luster. When polished as cabochons these stones exhibit a special characteristic that resembles the eye of a cat caught in headlights at night. The effect is caused by inclusions of fine, slender parallel fibers in the gem that reflect light into a single dynamic sliver of light running along the center of the crystal. Many other gems such as Tourmaline, Scapolite, Corundum, Spinel and Quartz also exhibit a cat's eye effect, but the term "Cat's Eye" generally refers to the cat's eye form of Chrysoberyl. All others are usually designated, for example "Quartz Cat's Eye" or "Tourmaline Cat's Eye" in the gemstone industry. Cat's Eyes of other gem types have traditionally been considered inferior to those that appear in Chrysoberyl.

Cat's Eyes are found in Myanmar, Brazil, China, Sri Lanka, and India. Those found in the Mogok mines in Myanmar and in Sri Lanka are considered the best. These localities produce the finest quality of Cat's Eyes called "milk and honey". When a flashlight is shined at the stone’s side it produces an amazing color zoning. Half of the stone will appear milky white while the other half remains a honey color. The green form is considered the next best. Apart from its color, Cat's Eye's value is judged by the brilliance of its luster, the sharpness of the eye, and its clarity and shape.


Wearing a quality Cat's Eye is believed to makes one wealthy, healthy, strongly determined, knowledgeable as well as providing protection from enemies. It will also help one gain insight, psychic powers, and can help one have better perception.
