The finest example of chatoyancy or “cat’s-eye” is that displayed by the gemstone chrysoberyl. The most desirable Chrysoberyl is slightly greenish yellow or brownish yellow, a color similar to honey. When a good quality, honey-colored cats-eye is held toward a concentrated light source with the chatoyant band at right angles to the light, the half of the stone closest to the light will show the honey color and the other half will appear milky. This is referred to as the “milk and honey” effect.
