Cat's Eye: The Living Light

Chatoyancy occurs when parallel fibrous inclusions reflect a concentrated band of light. Chrysoberyl cat's eye from Sri Lanka is the "king" of cat's eyes,showing a sharp, silvery-white eye on a honey to yellowish-green body. Other cat's eye gems include tourmaline, apatite, and sillimanite.

Evaluating Cat's Eye

The finest cat's eyes show a sharp, well-centered, bright eye that opens and closes dramatically with movement. Body color, eye sharpness, and the "milk and honey" effect (two-tone color split by the eye) determine value.
