Apatit är ett medelhårt kalciumfosfat (hårdheten 5 i Moh´s hårdhetsskala) med halt av fluor (oftast) eller klor. Färgen är vanligen vit, blågrön eller blåviolett och mineralet kristalliserar gärna som sexkantiga prismor. Små korn finns i de flesta bergarter medan större kristaller är mycket sällsynta.

Hydroxyapatite, also called hydroxylapatite (HA), is a naturally occurring mineral form of calcium apatite with the formula Ca 5 (PO 4) 3 (OH), but it is usually written Ca 10 (PO 4) 6 (OH) 2 to denote that the crystal unit cell comprises two entities.

Most "apatite" is fluorapatite, whereas hydroxylapatite is much less common and chlorapatite is very rare. Blue apatite is a prized mineral specimen by rock collectors for its vibrant royal blue color. Most of the apatite rock mined throughout the world is used to produce phosphate fertilizer. It is also used to produce animal feed supplements, phosphoric acid, elemental phosphorous, and phosphate compounds for the chemical industry.
