System:TrigonalColour:Dark brownish-black.
Lustre:Vitreous, DullHardness:7
Member of:Tourmaline Group
Name:Named for its relationship to Uvite


Tourmaline Group.
The Fe2+-analogue of uvite.

Note: The material studied by Selway et al. (1998) is very F-rich on the W site [(F0.49(OH)0.51)] and thus grades into the hypothetical "Fluor-feruvite."
