| Title | Large apatite crystals, Bahia State, Brazil |
|---|---|
| Description | Apatite is widely distributed in all rock types; igneous, sedimentary and metamorphic, but is usually just small disseminated grains or cryptocrystalline fragments. Large well formed crystals though can be found in certain contact metamorphic rocks. Very gemmy crystals of apatite can be cut as gems but the softness of apatite prevents wide distribution or acceptance of apatite as a gemstone. These hexagonal prismatic crystals are 6 cm in longest dimension. Apatite, Ca5(PO4)3(OH,F,Cl) is the most common phosphate mineral. |
