Although samples can have various color (green, brown, blue, yellow, violet, or colorless), the pure mineral is colorless, as expected for a material lacking transition metals. Along with hydroxylapatite, it can be a component of tooth enamel, but for industrial use both minerals are mined in the form of phosphate rock, whose usual mineral composition is primarily fluorapatite but often with significant amounts of the other.
Samples of this substance can have different shades (green, brown, blue, yellow, violet, or colorless), but the pure mineral itself is expected to be colorless due to its lack of transition metals. It can coexist with hydroxylapatite in tooth enamel and is usually mined from phosphate rock that contains fluorapatite along with other minerals.
