Product Details Gem Type : Tourmaline Cat's Eye Weight : 5.12 Cts Size : 9.8mm X 6.2mm X 5.9mm Shape : Oval Cabochon Clarity : Semi-Translucent Color : Green Treatment : None Origin : Brazil\ Description: The term cat's eye, or chatoyancy, is used to describe a phenomenal optical property in gemstones, in this case tourmaline. The effect, when present, appears as a bright, narrow slit similar to the pupils in the eyes of your favorite feline. This phenomenon is caused by parallel fibrous or needle-like inclusions that interfere with the passage of light throughout the crystal, scattering and reflecting light back to the viewer as a thin line. Cat's eye tourmaline can occur in many colors but particularly in green and pink varieties. Fine Cats eye tourmaline gems are found in a variety of colors and are generally semi-translucent to opaque. Look for a strong white eye running the length of the Cats eye tourmaline gemstone. Prices of cats eye tourmalines will depend on color, translucency, size and the sharpness of the cats eye effect. Tourmaline deposits can be found in many locations around the world. Brazil is famous for producing fine quality cat's eye tourmaline, but Africa and the USA (Maine and California) are also well-known for high quality crystals. Most of the tourmaline available today is mined from either Mozambique, Nigeria, Sri Lanka (Ceylon), Madagascar or Tanzania.
