hloromelanite: Specific Gravity 3.3 - 3.5 Moh hardness: 6.5 - 7 NaAlSi2O6

Chloromelanite is a very dark green, appearing black type of iron-rich Jadeite. I have
noticed some people are claiming this is a "type" of jade as is kJadeite and Nephrite.
Because Chloromelanite is Jadeite, it should be called Jadeite. However, just as brown
chalcedony is given the name sard (sometimes corneilian) and red chalcedony the name
carnelian, a varietal name is how Chloromelanite should be viewed.
