Cat's Eye Apatite Gemstone Information

Cat's eye apatite is a variety of apatite, which exhibits a rare optical trait known as 'chatoyancy'. Chatoyancy is a natural phenomenon known to occur in only a handful of different gem types, including chrysoberyl, the original and most well-known variety of cat's eye. The chatoyancy effect is a unique reflection of light that resembles the slit-eye of a cat when viewed under certain lighting conditions. The cat's eye effect is highly desirable and is usually the result of parallel fibers or needle-like inclusions formed within the stone. Cat's eye apatite is best viewed under direct lighting.

Although apatite is actually abundant in mineral form, it rarely occurs in transparent, gemstone-quality material. Owing to its extreme rarity, apatite is one of the 'lesser-known' gemstones and primarily classified as a collector's stone. Apatite is actually a group of phosphate minerals, composed of calcium phosphate, the very same material that makes up the teeth and bones of humans and other animals. Apatite is a primary source for phosphorus, an essential chemical used in bioenergetics and photosynthesis, and is widely used for the production of fertilizers, explosives, fireworks, pesticides, toothpaste, detergents and pharmaceutical products.

Cat's Eye Apatite Cut and Shape

Cat's Eye Apatite Treatment

Cat's eye apatite stones are typically untreated gems. Some specifically colored varieties, such as bright blue and green stones, may be color-enhanced though heat treatment. Irradiation treatment may also be used to improve chatoyancy. In any case, all gemstone treatments and enhancements should always be disclosed by trusted gemstone dealers.
