Physical properties

Hardness: 5 on Mohs scale. Color: Neon blue to teal. Luster: Vitreous to sub-resinous. Crystal Structure: Hexagonal. Cleavage: Indistinct. Specific Gravity: 3.16-3.22.

Formation & geological history

Formed in igneous pegmatites, metamorphic rocks (especially marble), and sedimentary hydrothermal veins. Commonly found in Precambrian to modern geological formations.

Uses & applications

Predominantly used as a source of phosphorus for fertilizers. High-quality specimens are used as gemstones and in crystal healing collections.

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 tourmaline or beryl.

Field identification & locations

Identify by its characteristic neon blue color and its inability to scratch glass (glass is usually 5.5-6). It is commonly found in Madagascar, Brazil, and Mexico. Collectors should look for its hexagonal crystal habits.
