Gem Profile- Apatite
by Judy Ellis
We've all played the game "One of these things is not like the other ..." OK, here goes: fertilizer, bones, teeth. But, in this case, all of these things are made of the same stuff. What is this material, you ask? Well, it's one of the most common phosphate minerals, or calcium phosphate. This mineral is used in fertilizer, it's what our teeth and bones are made of, and in the gem world, it goes by the name apatite (pronounced just like "appetite").
There are actually three different types of apatite. Although all are classified as the same material, they differ just a bit in their chemical structure. Calcium phosphate is called hydroxlapatite and is most common in tooth enamel and bones. Fluorapatite is most familiar as the fluoride we have in toothpaste and fluoridated water. Chlorapatite is the primary source of phosphate for plants, which is why we use it in fertilizer. Since all of them are basically the same material, we just use the mineral's name, apatite, to describe the bunch.

This stone is a softie

Apatite can be found in all types of rock, but usually only in small fragmented crystals. In some types of metamorphic rocks, large crystals of apatite have been found. The main reason apatite is not a popular gemstone is mostly due to the small size of the crystals and the softness of the stone. Apatite, a 5 on the Mohs hardness scale, is fairly soft and difficult to facet, which is why we don't see a lot of it on the market for gemstones. Apatite really should only be used in earrings, pendants, and as accent stones. If used in a ring, be careful not to be too rough, and set the gem in a protected setting. Clean apatite only with a soft cloth, and avoid any type of chemical cleaners.

The word apatite comes to us from the Greek "apatein," which means misleading or deceit. Interesting way to name a stone, don't you think? The next question you may ask is: What is so deceiving about apatite? Well, it can be mistaken for other stones like beryl, peridot, and tourmaline. Apatite comes in a variety of colors - yellow, pink, purple, green, and blue. The most recognizable color is the natural blue-green color from Madagascar that was first introduced to the market in the mid-1990s. This stone was an answer to the more expensive Paraiba tourmaline that sells for thousands of dollars per carat.

To attain a more desirable color, the stone was heat-treated to deepen and brighten the hues, creating neon apatite in teal, green, and a bright Paraiba-like blue. The stones can be clear and faceted or chatoyant and cabbed for a cat's eye effect.

Apatite's Value: Promotes peace and harmony

Apatite is a Gemini zodiac stone that helps the wearer remain focused. It also stimulates thoughts and ideas in addition to encouraging communication and intellect. It is useful in promoting inner peace and harmony, and thus helps to clear confusion and dissipate negative emotions. It also helps with bone and cartilage health and relieves arthritis and joint pain. On a diet? Apatite also raises the metabolic rate while decreasing appetite. It is a stone, they say, of manifestation, learning, health, and harmony.

Not only is apatite found readily on the earth, it's also been found on the moon - Apollo astronauts brought back rocks that have been shown to contain apatite with enough water in the form of hydroxyl (calcium hydroxide) to cover the moon's surface in approximately 1 meter of liquid if you were able to extract it all.
Apatite for a road trip!

Road Trip! (You thought I'd forgotten!) The most recognizable apatite comes from Madagascar. It would be fun to travel there, but if you're like me and on a budget, just rent the movie and laugh at the penguins.

Other apatite-rich deposits are in Mexico, Brazil, and the United States. Maine brings us some beautiful purple apatite from Apatite Mountain, which consists of old quarries now managed by the City of Auburn. There is public access to poke around and try your hand at rock hounding. You may find some purple apatite, lepidolite, smoky quartz, and tourmaline. Please only use hand tools and make sure you prepare for a day of dirt, digging and no facilities.

For those of us in the Western U.S., a fun-filled trip to the Oceanview Mine in southern California is in order. For a fee, you can spend the day digging for a variety of gems, including apatite, quartz, and tourmaline. The mine is located near Pala in San Diego County. Since it's a working mine, it's open to the public only a few days per week. Bring water, sunscreen, lunch, and a good pair of gloves - the mine provides everything else. You get to keep what you find at no additional charge and can even take a 5-gallon bucket of screened gravel home with you if you like.
