Apatite refers to closely related minerals of the phosphate family with similar chemical and physical qualities. They are seen in phosphate rock and used in producing chemicals including acids and fertilizers. They may be used as gemstones and cabochons depending on their clarity and colours. Apart from phosphorus, they contain hydroxylapatite, calcium and minute quantity of flouride.
Apatite has a mohs hardness of 5 and may be of different colours of yellow, brown, purple, pink and sometimes may be colourless. They are prone to breakage and may be seen in both sedimentary, igneous and metamorphic rocks. It’s distinct colours makes it a great fit in gemstone production.
