Apatite

Posted on: September 26, 2011

Apatite is infrequently used as a  gemstone. Transparent  stones of clean color have been faceted,and chatoyant  specimens have been cabochon cut. Chatoyant stones are known as cat’s-eye apatite. transparent green stones are known as asparagus stone, and blue stones have been called maroxite. Crystals of rutile may have grown in the crystal of apatite so when in the right light, the cut stone displays a cat’s eye effect.

Chemical Symbol :
Ca5(PO4)3(OH,F,Cl)

Chemical Make-up :
Apatite is made up of basic Fluoro-Calcium, Chloro-Calcium and Hydroxyl
Phosphate minerals.

 History:
The word Apatite is derived from the Greek word apate, meaning to decieve. This was primarily due to the fact that Apatite was often mistaken for rarer, more valuable gemstones such as Beryl, Olivine and Peridot. Apatite falls into two categories, Chlor-Apetite (Chloro-Calcium), and Flour-Apetite (Flouro—Calcium).

Apatite enhances the wearers learning abilities, self-confidence and creativity. In addition to this, Apatite is an aid to achieving a deeper state of meditation and to increasing insightfulness. Apatite eases hypertension and decreases hunger, or “appetite”. In addition to this, Apatite is said to be a good gemstone for unblocking any of the chakras.

 Care & Cleaning :
Apatite is particularly sensitive to abrasives, chemicals, heat, ammonia and acids. Ultrasonic cleaners and steamersshould also be avoided. Apatite is best cleaned with warm, soapy water and a soft cloth. Apatite
jewelry should be stored on its own in a lined jewelry box, away from harder jewelry, which may cause
scratches or abrasions.

 Evaluation :
Apatite is rated at 5 on the Moh’s Scale of Hardness. Apatite can be worn every day in brooches, earrings and pendants, but it is generally considered too soft to be worn daily in a ring.

Apatite can be found in many colors, including, blue, brown, colorless, green, pink, purple, red, violet and yellow. There is also a “Cat’s Eye” Apatite. Brown, green and yellow are the commonly occuring colors, with blue, colorless, pibk, red, violet, and the most recently discovered neon blue-green examples being the rarest and therefore most valuable Apatite colors.

When buying Apatite gemstones, the two most impotant factors to consider are color and clarity. Gemstones with good color saturation and few inclusions are inherently more valuable and command higher per Carat prices.

 Sourses: There are known Apatite desposits in Algeria, Austria, Burma (Myanmar), Brazil, Canada, Egypt, Germany, India, Israel, Kenya, Madagascar, Mexico, Morocco, Norway, Portugal, Russia, Spain, Sri Lanka (Ceylon), Sweden, Tunisia and the United States (California, Utah, Nevada, Idaho, Wyoming and Montana).

Apatite is the most common phosphate mineral, and is the main source of the phosphorus required by plants. The bones and teeth of most animals, including humans, are composed of calcium phosphate, which is the same material as Apatite.
