Native phosphate of lime, occurring usually in six-sided prisms, color often pale green, transparent or translucent.
Phosphate mineral, which can be in three forms depending on its chemistry. Forms are Fluorapatite (fluorine-rich), Chlorapatite (chlorine-rich and Hydroxylapatite (rich in hyrdroxides). It is also what most teeth of mammals are made of!... More
A relatively common mineral available in a wide and range of attractive colors: pink, yellow, green, blue, violet and colorless (white). Clear, gem quality crystals, are rare and usually small. It is a softer stone, not well suited to rings, but an excellent choice for earrings. Known to promote communication and mental clarity.
(ap'-a-tite) 1. A group of hexagonal minerals consisting of calcium phosphate together with florine, chlorine, hydroxyl, or carbonate substituting for the phosphate radical having the general formula Ca5 (PO4)3 (F,Cl,OH). Apatite occurs as accessory minerals in igneous and metamorphic rocks, ore deposits; and most commonly as fine-grained and often impure masses as the chief constituent of phosphate rock. A material similar to apatite makes up bones and teeth.
Calcium phosphate, an insoluble mineral that confers hardness and rigidity to bone tissues.
A complex mineral form of calcium phosphate, which contains fluoride. Apatite is the major constituent of tooth enamel.
A common mineral that comes in a variety of forms and colors. It can be an igneous or a sedimentary rock.
a common complex mineral consisting of calcium fluoride phosphate or calcium chloride phosphate; a source of phosphorus
a phospate mineral with the chemical formula of Ca5(PO4)3(F,Cl,OH)
Apatite (calcium phosphate) is a clear to opaque stone that comes in many colors, including green, yellow, blue, violet, and yellow-green (called asparagus stone). Some apatite stones show a cat's eye asterism. This stone is rarely used in jewelry because it is brittle and soft. Apatite comes from the Greek word for "deceit," because it was easily confused with other minerals. Apatite has a hardness of 5 and a specific gravity of 3.15-3.22.
this mineral comes in gem quality. Occurs in a transparent green, blue, violet purple, pink, yellow, or colorless material. Grays and brown are the non-gem varieties. Sources: Ceylon, Burma, Bohemia, Mexico, and Maine (USA).
Apatite is a naturally occurring beautiful gemstone. While it is known for its asparagus green hues, apatite actually can be found in a wide variety of colors ranging from colorless to pink, yellow, blue and violet. On Mohs’ scale of hardness, apatite is a soft 5. It has a vitreous luster and primary sources include Burma (Myanmar), Brazil, India, Kenya, Madagascar, Mexico, Norway, Sri Lanka, South Africa and the United States. (See Apatite Facts.) (Note: Sources listed in order of primary and secondary deposits.)
A form of calcium phosphate that is a clear to opaque and comes in many colors including green, yellow, blue, violet, and yellow-green (called asparagus stone). Some apatite stones are chatoyant, like the stone tiger's eye. It is usually too brittle and soft to be used in jewelry.
Is an abundant mineral found in many types of rock but most gem quality material is associated with pegmatite.
