Apatite is a calcium phosphate mineral found in a variety of colors such as yellow, blue, green, gray, and brown. The most important colors for metaphysical use are blue, green, and gold. Apatite was first discovered in 1786 by A.G. Werner ,but it’s name came from the Greek word meaning “to deceive” , due to Vickers hardness of 400, a bending strength of 43 MPa, apatite (TMA®)” for use as a bone replacement in humans.

A certain mineral sample cannot scratch apatite, but apatite can scratch the Apatite minerals are relatively soft and are used to describe the 5 hardness on the Mohs scale. Cleavage is poor and develops along the C(0001).
The composition and distribution of the REEs within the concentrates are studied using ICP-MS, XRD and SEM-EDS/EPMA, as well as the melting point and heat of fusion using DTA-TGA-MS. Apatite is known by gemstone expert especially for two colors: the Paraiba-like blue-green, and the leek-green color that once earned apatite the name “asparagus stone”. How strong is apatite? The gem has a relatively consistent hardness and serves as the index mineral for a hardness of five in the Mohs hardness scale. Apatite is the name of a group of phosphate minerals that have a familiar chemical composition and share the same physical properties. They are a significant component of phosphorite and used to make chemicals, acids, and fertilizers.
