apatite crystal-green-1
Mexico
Apatite is calcium phosphate, the same
mineral that your teeth are made of. This
type of green apatite from
Mexico is known as "asparagus stone" because the
crystal resembles asparagus in
color and shape. Even though your teeth are made
of apatite, aren't you
glad that they are not green like this crystal?
