Apatite
Apatite is a group of phosphate containing minerals. The name comes from the Greek word apate, which means, "to deceive." Apatite was often confused, therefore "deceiving" many, with some of the more valuable gems such as tourmaline, olivine, peridot, topaz and beryl.
Apatite is believed to decrease appetite (hunger) as well as enhance insight, creativity and learning. It is said that wearing apatite will enhance focus, clarity for concentration, intellect, acceptance, and unconditional love. This acceptance and unconditional love relates to the self as well as from others.
Deposits are found in Burma (Myanmar), Brazil, India, Kenya, Madagascar, Mexico, Norway, Sri Lanka, East and South Africa, Spain, Russia (Kola Peninsula), Canada, and the United States.
