Tiger Eye

What creates the silky, moving band of light in tiger eye?

The characteristic "cat's eye" effect, known as chatoyancy, is created by parallel fibrous structures within the stone – originally asbestos fibers that were replaced by quartz while retaining their parallel arrangement. When light hits these fibers, it creates a moving band of light that appears to glide across the surface as the stone is turned. This optical phenomenon is similar to the way light reflects off a spool of silk, which is why the effect often appears silky or smooth.

Why do some tiger eye stones show different colors?

Natural tiger eye can occur in several color variations depending on mineral content and oxidation states. The classic golden-brown variety gets its color from iron oxide, while red tiger eye (also called ox eye) forms when the iron oxidizes further. Blue tiger eye, sometimes called hawk's eye, is the unoxidized form of the stone. Some specimens may show multiple colors or gradients between these variations. All these colors are natural, though some commercial tiger eye may be dyed or treated to enhance specific hues.

How should I polish and maintain my tiger eye's shine?

Tiger eye is relatively hard (7 on the Mohs scale) and can be safely cleaned with warm, soapy water and a soft cloth. After cleaning, dry thoroughly to prevent water spots that might dull its surface. To maintain its glossy finish, avoid exposing your tiger eye to harsh chemicals or abrasive materials. Regular dusting with a soft cloth will help maintain its shine. While the stone is durable, its chatoyant effect shows best on well-polished surfaces, so store it separately from harder stones to prevent scratches. If your tiger eye becomes dull over time, it can be repolished by a professional lapidary.
