Apatite is actually three different minerals depending on the predominance of either fluorine, chlorine or the hydroxyl group: calcium (fluoro, chloro, hydroxyl) phosphate.

The name apatite is quite appropriate, considering this mineral makes up the teeth in all vertebrate animals (and teeth are used to satisfy appetite!).
APATITE
Overview: The name Apatite comes from the Greek word "apate" that means "to deceive" in allusion to its similarity to other more valuable minerals such as olivine, peridot and beryl.
Apatite Apatite is mineral found in many different parts of the world. It is not a well known gemstone, and actually has more uses outside the field of jewelry. Apatite is a soft stone, but can be very brittle.

Apatite has appeared on the gem markets of the world as a very affordable substitute for Paraiba tourmaline. Canada is the source for the intense sea-blue and green stones can be easily mistaken for the much more expensive tourmalines.
Apatite is the most collectable mineral at Philips Mine because they occur as translucent to opaque brown, yellow or green crystals up to one and a half inches long.

Chatoyancy The cat's eye effect sometimes seen in gemstones such as chrysoberyl, apatite and tourmaline is known by the technical name of chatoyancy.
There is a well-known scale of hardness as measured by scratching, known as Moh's Scale, which lists diamonds at 10, corundum (ruby and sapphire) at 9, topaz at 8, quartz at 7, feldspar at 6, and apatite at 5.
(Apatite)
Phosphorescence - A lingering emission of light following exposure to Ultraviolet light or other energy.
Pinacoid - A crystal face parallel to two crystal axes (three in the hexagonal system).
A common example is apatite (Ca5(PO4)3(OH)) a principal component of bones and teeth. The other trivalent tetrahedral polyanions, arsenate AsO43-, and vanadate VO43- are structurally and chemically similar and are included in this group.
Phosphorus
A highly reactive, poisonous, nonmetallic element occurring naturally in phosphates, especially apatite, which is found as a white, or yellowish, translucent waxy substance, having a characteristic disagreeable smell and a faint glow.

Other forms present may include pinacoid and prisms. The chief minerals crystallizing in this class are those of the apatite group.

Mohs, a German mineralogist, as an assessment of “scratch hardness' by ranking 10 different stones from hardest to softest. His list includes the following:
10. Diamond (Hardest)
9. Sapphire
8. Topaz
7. Quartz
6. Orthoclase Feldspar
5. Apatite ...
True topaz (precious topaz) he called 8. Quartz (amethyst and quartz "topaz") was given the number 7. Felspar (moonstone) was rated 6, the mineral apatite 5, fluorspar 4, calcite 3, gypsum 2, and talc 1.
show a considerable variation in resistance to abrasion. The hardest direction in diamond is parallel to the faces of the octahedron.

2. Gypsum 7. Quartz
3. Calcite 8. Topaz
4. Fluorite 9. Corundum
5. Apatite 10.
For example, in actual hardness, the diamond has been found to be up to 150 times as hard as corundum, the next lower on this scale.According to scale, the hardness in order is:1- Talc 2 - Gypsum 3 - Calcite 4 - Fluorite 5 - Apatite 5.5-6.
