Apatite is actually three different minerals depending on the predominance of either fluorine, chlorine or the hydroxyl group: Calcium (Fluoro, Chloro, Hydroxyl) Phosphate. These ions can freely substitute in the crystal lattice and all three are usually present in every specimen although some specimens are almost 100% pure in one group.
The mineral Apatite is quite common but gem quality specimens are rare, especially in sizes over 1 Carat.
As a relatively "soft" gem (a hardness of 5 on the MOHS scale) it is best used in earrings and pendants.
