Did you know that Apatite was once used
as a source of phosphate for fertilizer? Today, mainly
phosphorites are used. Apatite is also believed by crystal
healers to be useful to help improve one's coordination and
to strengthen muscles, and to help suppress hunger and ease
hypertension.
Apatite (Ca5(PO4)3(F,Cl,OH)) is a
common accessory mineral in many types of igneous,
metamorphic and sedimentary rocks. The largest Apatite
deposits are associated with alkalic rocks. Apatite is
actually three different minerals depending on the
predominance of either fluorine, chlorine or the hydroxyl
group: Calcium (Fluoro, Chloro, Hydroxyl) Phosphate. These
ions can freely substitute in the crystal lattice and all
three are usually present in every specimen although some
specimens are almost 100% pure in one group.
The color in Apatite is often due to
the presence of rare earth elements or by natural
irradiation. Apatite is a clear to opaque gem that comes in
many colors, including green, yellow, blue, violet, and a
yellow-green variety, originally mined in Spain, commonly
called “Asparagus Stone” because of its similarity in color
to the vegetable. Cat's Eye Apatite gems are also known.
Apatite is found in Brazil, Madagascar, Russia, Myanmar
(Burma), Sri Lanka (Ceylon), Canada, East Africa, Sweden,
Spain and Mexico.
A rare variety are rich purpled gems from Maine. Brazil
is the traditional source of gem quality Apatite. Quite
attractive, Brazilian Apatite is a medium dark to dark,
strongly saturated blue color. However, recent finds of what
is now widely referred to as Neon Apatite in Madagascar has
added to the popularity of this gem. The neon ranges from a
green to blue and exhibits excellent saturation. |
