A gemological chameleon, Apatite’s name comes from the Greek ‘apatao’ (to deceive) due to a historical confusion with other gemstones. Apatite’s propensity for deception even has its roots in Greek mythology. One of the spirits released from Pandora’s Box, Apate is the goddess of deceit, fraud and trickery. While its name is really about how Apatite can fool you, it does sound a bit like ‘appetite’ and there actually is a ‘hunger’ connection; a calcium phosphate, Apatite crystals are one of the components of teeth and bones in all vertebrate animals.
Typically colored by rare earth elements, Apatite is a gorgeous gem that occurs in blue, brown, gray, green, pink, purple, teal, violet, white, and yellow. Apatite is actually several different minerals depending on whether chlorine, fluorine, hydroxyl or strontium replaces the calcium.
