Calcium, strontium, lead, and sodium together with potassium-fluorine-chlorine-hydroxyl phosphate form apatite. This chemically complex substance is a major constituent of mammalian teeth and bones, forming sixty-five percent of ivory, the rest being largely collagen. It is put to use in the manufacture of phosphate fertilizers. Apatite crystals may be violet, pink, blue, brown, gray, yellow, or colorless. A yellowish-green shade is its most usual color, which has earned it the name “asparagus stone.” The name apatite comes from a Greek word meaning to deceive in allusion to its similarity to other more valuable minerals such as olivine, peridot and beryl. Another variety, a blue-green sample, is called moroxite in Norway. Though apatite is sometimes cut and faceted into talismanic gemstones, it is usually considered too soft to be used as jewelry.

Aloofness and negativity are dissolved by apatite to allow expression of your spiritual and emotional strengths. Apatite is useful when attempting to unify the energies of more than one stone, or emotional, intellectual, physical, and spiritual forms. The development of clairvoyance, clairaudience, clairsentience, and awareness of nature spirits is enhanced by apatite. It has been put to use in contacting extraterrestrial intelligences, enhancing telepathy, and encouraging past life recall.

Apatite, which is found in all the major rock types — igneous, metamorphic, and sedimentary — is actually made up of three distinct minerals. These are Fluorapatite, Chlorapatite, and Hydroxylapatite; the exact proportions of each vary between specimens, but they are almost always present. The vast majority of apatite occurences are as tiny grains spread throughout the parent matrix, but when large crystals form, they can be good enough to be used as gems. These are generally considered to be too soft for regular use in jewelry, however. Apatite has a specific gravity of 3.1 - 3.2, a vitreous to greasy luster, and a white streak.
