The Phenomenon of Cat’s Eye
In the realm of gemology, the cat’s eye effect, also known as chatoyancy, is an optical phenomenon that manifests as a bright line of light across the surface of a gemstone. This effect occurs due to the reflection of light from fibrous structures within the cat’s eye or from needle-like inclusions. The term “chatoyancy” is derived from the French word “Å“il de chat,” meaning “cat’s eye.” In sillimanite cat’s eye, this effect adds an enchanting and mesmerizing quality to the gem, making it highly coveted among collectors and jewelry enthusiasts alike.
In chrysoberyl cat’s eye, chatoyancy is typically caused by the presence of rutile, a mineral composed mostly of titanium dioxide. Interestingly, studies have found that these precipitates align perpendicularly, enhancing the distinctive band of light that gives the gem its signature cat’s eye appearance. This alignment is due to the crystal structure of rutile, which matches one of the axes of the chrysoberyl crystal, resulting in a preferred direction for light reflection. The chatoyancy effect is most visible under a direct light source, creating a captivating band that appears to glide across the surface of the cat’s eye as it is moved.
