Apatite comes in attractive colors - blue,violet, purple , yellow-green and, blue-green.Although a soft material, it is widely used injewellery due to its bright and attractive colors.Apatite is also very heat sensitive.The term cat\'s eye, or chatoyancy, is used todescribe a phenomenal optical property in gemstones,in this case apatite. The effect, when present,appears as a bright, narrow slit similar to thepupils in the eyes of your favorite feline.This phenomenon is caused by parallel fibrousor needle-like inclusions that interfere with the passageof light throughout the crystal, scattering andreflecting light back to the viewer as a thin line.Chatoyancy is the only known phenomenon seen in apatite.The most common colors for cat\'s eye apatite arebluish green, green and yellow. Brazil andSri Lanka are the principal sources of chatoyant apatite,although it may also be found inMadagascar and Tanzania.
