'''A calciumphosphate'''
* Ca5(PO4)3(OH)
* Mohs 5 (defining mineral)
* hexagonal

There are hydroxy, fluorine, chlorine, and even bromine versions. 
Fluorine has more influence on chemical resistance than mechanical properties. 
In advanced [[gem-gum]] nanosystems the interior will be well sealed and [[fluorine]] is not to common and can be toxic when released. So in most cases the hydroxy (or chlorine) version will likely be preferable.

Apatite is a well known biomineral forming our teeth and boned. 

initiated by addition of turquoise which is harder than [[apatite]] the best known phosphate (which is making up our teeth and bones and is forming green gems)

== Phosphates harder than apatite ==

There are harder phosphates than apatite
possibly at the expense of lower symmetry crystal structure
One example being [[Turquoise]]

{{wikitodo|continue skimming for the hardest phosphate with [[desirable properties for a gemstone base material|other properties]] being good too}}
