Colour:
colourless
Lustre:
Vitreous
Specific Gravity:
3.12 (Calculated)
Crystal System:
Orthorhombic
Name:
Named pertsevite by W. Schreyer, T. Armbruster, H.-J. Bernhardt, and O. Medenbach in 2003 in honor of Nikolai Nikolayevich Pertsev (1930 - ), mineralogist and petrologist with the Institute of Geology of Ore Deposits, Petrography, Mineralogy, and Geochemistry, Russian Academy of Sciences (IGEM), for his work on borate minerals. Pertsev had collected the kotoite marble and donated the thin section that was studied.

The name was suffixed by (F), for fluoro-dominant, in 2009 after the hydroxyl-dominant phase was approved as a new mineral by the IMA.
F-analogue of Pertsevite-(OH).
