Cat-eye tourmaline is a kind of tourmaline. This tourmaline yield is relatively small, and it has a cat-eye effect under the illumination of the light source. It is very beautiful and charming, so the collection value is very high.
The cat's eye effect of tourmaline is because the tourmaline has parallel tubular inclusions. The inclusions reach a certain density. In the direction of the vertical parallel inclusions, there will be a bright line under the illumination of the light source. There is a cat's eye effect.
The cat's eye is not the name of the gem, but the cat's eye effect on some gemstones, and then named according to what the gem is. If the gemstone is quartz, it is called a quartz cat's eye. There are many types of gemstones with cat's eye flash. According to statistics, there are 30 kinds of stones. In addition to quartz cat eyes and gold-green cat eyes, there are also pyroxene cat eyes and aquamarine cat eyes. Since the golden-green cat's eye is the most famous and precious, it is customarily referred to as the cat's eye, while other cat's eye tourmalines cannot be called.
