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 display a range of colors (green, brown, blue, yellow, violet, or colorless), but the pure mineral itself is typically colorless, as it lacks transition metals. It can be found in tooth enamel alongside hydroxylapatite and is often extracted from phosphate rock, which typically contains fluorapatite with varying amounts of other minerals.
