Phosphates

Home Minerals Phosphates
The phosphate minerals are characterized by way of the tetrahedral [PO4]three− unit, despite the fact that the structure can be generalized, and phosphorus is replaced by means of antimony, arsenic, or vanadium. The most common phosphate is the apatite group; not unusual species inside this organization are fluorapatite (Ca5(PO4)3F), chlorapatite (Ca5(PO4)3Cl) and hydroxylapatite (Ca5(PO4)3(OH)). Minerals on this group are the primary crystalline components of teeth and bones in vertebrates.

Apatite Mineral Definition Properties and Pictures
Apatite is a very common mineral, but transparent gemstone-quality apatite is extremely rare. Despite the fact that apatite is the defining mineral for 5 on Mohs scale of hardness, the gemstone remains virtually unknown to most, and is seldom found in jewelry stores.
