Physical properties

Hardness: 5 on Mohs scale; Color: Electric neon blue to teal; Luster: Vitreous to sub-resinous; Crystal System: Hexagonal; Specific Gravity: 3.1-3.2; Fracture: Conchoidal to uneven.

Formation & geological history

Formed in pegmatites, metamorphic rocks, and igneous rocks through the cooling of magma or hydrothermal activity. Often found in deposits dating back to the Proterozoic eon.

Uses & applications

Primarily used as a collector specimen and in jewelry (though soft for rings). Major industrial use for磷 (phosphate) in fertilizers and phosphoric acid production.

Geological facts

Apatite is the mineral that makes up the teeth and bones of all vertebrate animals. The name comes from the Greek word 'apate', meaning 'to deceive', because it was often confused with other minerals like peridot or beryl.

Field identification & locations

Identify in the field by its distinct hexagonal crystal habit and its hardness (can be scratched by a knife but not a penny). Commonly found in Brazil, Madagascar, Mexico, and Myanmar. Use caution as it is heat sensitive.
