Apatite Gemstone
Apatite is named for the Greek word apate, which means "deceit" since Apatite is similar in appearance to many other minerals. Apatite is infrequently used as a gemstone. Transparent stones of clean color have been faceted, and chatoyant specimens have been cabochon-cut.
Apatite is a field term for unidentified calcium phosphate members of the apatite group. The bones and teeth of most animals, including humans, are composed of calcium phosphate, which is the same material as Apatite. The fluorescence of Apatite stone is lilac to pink.
