Physical properties

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

Formation & geological history

Formed as a primary mineral in igneous rocks, metamorphic rocks, and occasionally in sedimentary environments. High concentrations are often found in pegmatite veins. While found across many geological ages, large deposits in Madagascar (common source for this color) are hundreds of millions of years old.

Uses & applications

Apatite is the main source of phosphorus for the fertilizer industry. In this polished form, it is used as a decorative collector's piece, in lapidary work for cabochons, and in metaphysical meditation practices.

Geological facts

Apatite is the defining mineral for '5' on the Mohs scale of mineral hardness. Its name is derived from the Greek word 'apate', meaning 'to deceive', because it was historically often mistaken for other minerals like fluorite or beryl.

Field identification & locations

Identify in the field by its distinct hexagonal crystal shape (if unpolished) and its inability to scratch glass but ease of being scratched by a steel blade. Commonly sourced from Madagascar, Brazil, and Mexico. Collectors look for high 'neon' saturation and clarity.
