CAT EYE - QUARTZ
Characteristics of the mineral.
Crystalline quartz (silicon oxide) sometimes contains internal fibers and voids and also forms a very beautiful quartz "cat's eye" (photo on the left) of grayish shades, which, although it does not have such vivid opalescence as a chrysoberyl cat's eye, Successfully compete with him. This is a very rare and expensive form and a kind of quartz. Chemically pure quartz is devoid of color, it is water-transparent and grayish. It also forms much more widespread opaque, distinctive species with fine-crystalline parallel inclusions of goethite and crocidolite, known as "tiger's eye" (yellow-brown) and "falcon eye" (black-blue, blue and very rarely pink). Any "eye" needs to be rotated under the light to see a gentle overflow of color and a glare running along the surface of the mineral.
If quartz forms pseudomorphs over intergrowths of parallel-fiber varieties of hornblende, crocidolite and asbestos, a cat's eye is formed. On the break there is a strong silky shine, which can be strengthened with a cut in the form of a cabochon. In this case, a sharp bright line appears on the stone or an arcuate radiance resembling the pupil of the eye of an animal or a bird of prey. The cat's eye is called similar formations of green, gray, grayish-green color. The effect of radiance and the characteristic color are caused by inclusions of asbestos. If these inclusions are excessively numerous, on the fracture, the thin veins of the mineral become fluffy and unsuitable for jewelry processing. The largest deposits of this stone are on. Sri Lanka, where he is found in placers of gemstones in the form of pebbles the size of a walnut. In the CIS, these amazing stones come across in the Urals. In addition, there are cat eye deposits in India, USA, Mexico. In other places, the quartz cat's eye is very rare.
