Apatite gemstone  is loved by collectors for its many different colors and forms. Apatite gemstone is  seldom found in jewelry stores and virtually unknown to the general public.  Only with the recent availability of the neon blue-green variety from Madagascar, has its jewellery use increased.  But this gem lacks their toughness and hardness. At 5 on the Mohs scale, apatite must be cut, set, and worn gently. Earrings, pendants, pins, and tie tacks are probably safe, but ring use should be limited to occasional wear pieces with protective settings.


.Apatite gemstones are available in yellows and various shades of blues and greens. Some of the blues show chatoyancy and can be cut as cat's eyes. A rare variety is a rich purple from Maine. Blue Brazilian stones are second in demand. A light green variety of apatite carries the trade name "asparagus stone".

 

Apatites are found in Brazil,  Kenya, Madagascar,  Myanmar (Burma), Norway, Sri Lanka, India, South Africa, the United States and Mexico.
