Apatite (Chest Gem)

Apatite is a Homeworld Gem and an original character made by BlueWhiteLight.

Appearance
Apatite has a slim-build with a light blue complexion, short turquoise hair, turquoise eyes with white pupils, no nose, no teeth and a long tongue. He has frog legs and hands and wears a short shawl. His gemstone is located on his chest.

Personality
Apatite is described as "obedient" and does whatever Moonstone tells him to do. Deep down, however, he hates working for Moonstone.

Abilities
Apatite possesses standard Gem abilities including bubbling, shapeshifting, fusion, regeneration, agelessness and superhuman strength/durability.

Skillset

 * Shuriken Proficiency: Apatite can summon shurikens.
 * Jump Boost: Apatite can jump really high.

Gemology
Gemstone Information
 * Apatite is a group of phosphate minerals, usually referring to hydroxylapatite, fluorapatite and chlorapatite, with high concentrations of OH−, F− and Cl− ions, respectively, in the crystal. The formula of the admixture of the three most common endmembers is written as Ca10(PO4)6(OH,F,Cl)2, and the crystal unit cell formulae of the individual minerals are written as Ca10(PO4)6(OH)2, Ca10(PO4)6F2 and Ca10(PO4)6Cl2.


 * The mineral was named apatite by the German geologist Abraham Gottlob Werner in 1786, although the specific mineral he had described was reclassified as fluorapatite in 1860 by the German mineralogist Karl Friedrich August Rammelsberg. Apatite is often mistaken for other minerals. This tendency is reflected in the mineral's name, which is derived from the Greek word απατείν (apatein), which means to deceive or to be misleading.


 * Apatite is one of a few minerals produced and used by biological micro-environmental systems. Apatite is the defining mineral for 5 on the Mohs scale. Hydroxyapatite, also known as hydroxylapatite, is the major component of tooth enamel and bone mineral. A relatively rare form of apatite in which most of the OH groups are absent and containing many carbonate and acid phosphate substitutions is a large component of bone material.


 * Fluorapatite (or fluoroapatite) is more resistant to acid attack than is hydroxyapatite; in the mid-20th century, it was discovered that communities whose water supply naturally contained fluorine had lower rates of dental caries. Fluoridated water allows exchange in the teeth of fluoride ions for hydroxyl groups in apatite. Similarly, toothpaste typically contains a source of fluoride anions (e.g. sodium fluoride, sodium monofluorophosphate). Too much fluoride results in dental fluorosis and/or skeletal fluorosis.


 * Fission tracks in apatite are commonly used to determine the thermal histories of orogenic (mountain) belts and of sediments in sedimentary basins. (U-Th)/He dating of apatite is also well established from noble gas diffusion studies for use in determining thermal histories and other, less typical applications such as paleo-wildfire dating.


 * Phosphorite is a phosphate-rich sedimentary rock, that contains between 18% and 40% P2O5. The apatite in phosphorite is present as cryptocrystalline masses referred to as collophane.
