| 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. |
