Physical properties
Hardness: 5 on Mohs scale; Color: Teal to deep neon blue; Luster: Vitreous (glassy); Crystal Structure: Hexagonal; Cleavage: Poor; Specific Gravity: 3.1-3.2
Formation & geological history
Formed through igneous processes in granitic pegmatites or metamorphic processes in marble. It is a group of phosphate minerals commonly found in iron-rich sedimentary rocks and hydrothermal veins.
Uses & applications
Primary source of phosphorus for fertilizer; used as a gemstone in jewelry (though soft); used in laser technology and for mineral specimen collecting.
Geological facts
Apatite is the specific mineral that defines the '5' on the Mohs scale of mineral hardness. The human body also contains a form of apatite, as it makes up the mineral component of tooth enamel and bones.
Field identification & locations
Identify by its characteristic teal color and inability to scratch glass (glass is harder). Commonly found in Brazil, Madagascar, Mexico, and Myanmar. Often confused with Beryl or Tourmaline due to its color.
