Description: This specimen is a blue crystal. It can also be green, grey-green, white, brown, yellow or red!

Apatite is called a deceiving stone because it has been confused with other minerals, such as lapis lazuli.

Apatite is economically important as a fertiliser, because it's a phosphate. Luckily not all Apatite looks as pretty as this piece, otherwise it would be a shame to grind it up for fertiliser.

Apatite is calcium phosphate, which is what our teeth and bones are made of.
