Cat's Eye Opal Value Guide

This contemporary African Cat's Eye Opal is a rare specimen prized for its distinct chatoyancy, a sharp band of light caused by internal fibrous inclusions. Unlike traditional play-of-color opals, this untreated natural gemstone is highly collectible for its specific optical phenomenon and historical association with hope and purity.

What affects the value of Cat's Eye Opal?

• The sharpness and centering of the 'eye' or light band significantly impact the $1,200 valuation.
• Clarity and body color of the natural opal, with more translucent or vivid bases commanding higher prices.
• The quality of the cabochon cut, which must be perfectly symmetrical to properly display the chatoyant effect.
• Origin and treatment status, as natural, untreated stones from Africa are more desirable to collectors.

How to Identify Cat's Eye Opal?

• Verify the presence of a single, sharp band of light (chatoyancy) that moves across the surface when the stone is rotated.
• Inspect for natural fibrous inclusions under magnification, which are characteristic of authentic African cat's eye varieties.
• Confirm the material is natural, untreated opal rather than synthetic glass or fiber-optic simulants.
• Check for the specific waxy luster and density typical of genuine African opal deposits.

History of Cat's Eye Opal

Opal has been admired for centuries, with its origins dating back to ancient Rome where it was considered a symbol of hope and purity. The unique 'cat's eye' effect, known as chatoyancy, is caused by fibrous inclusions within the stone, reflecting a single band of light. This particular variety of opal is highly prized for its captivating play of light.
