It is a rare and valuable gemstone, which is often underrated as being a semi-precious stone. Chatoyancy or chatoyance, is literally taken from the French word meaning cats eye. The effect is a strong banded reflection caused by tube-like or needle-like crystals running along the length of the stone. The optical effect is seen best in chrysoberyl Quartz varieties, but is also found in a few other gemstones like Star Sapphires and Tigereyes. Genuine Catseye Quartz is very rare. Most of the inexpensive Catseye sold on the jewelry market today is a manmade version of quartz crystal glass.Kindly Note: 1.Since the size above is measured by hand, the size of the actual item you received could be slight different from the size above. 2.Due to lighting effects, monitors brightness/contrast settings etc, there could be some slight differences in the color tone of the pictures and the actual item. 3.All stone beads are unique and genuine.
