| Apatite
is very rarely encountered as a
gem material but occurs in transparent
form in blue, violet, purple , yellowish
green and, bluish green colors.
With a hardness of 5, apatite is
not a very hard stone but it is
still used in jewelry because of
its attractive color. Apatite is
also very heat sensitive and as
a result, there are few lapidaries
that can cut it at all.
