Cat's Eye Tourmaline
about Cat's Eye Tourmaline
Tourmaline is a crystal silicate mineral compounded with elements such as aluminium, iron, magnesium, sodium, lithium, or potassium. Tourmaline is classed as a semi-precious stone and the gem comes in a wide variety of colors. The name comes from the Sinhalese word "turamali" or "toramalli", which tranlates to "many colors" or stone of many colors. Cat's eye tourmaline is rare. The most prominent colors are Green, Pink and blue but exist in other colors. The Chatoyant cat's eye effect is due to fine silk in the gemstone that when cut and perpendicular to the direction of the silk pattern creates the Chatoyant cat's eye effect. Tourmaline is a October birthstone.
