Melanostibite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
Mn2+(Sb5+,Fe3+)O3
Colour:
black
Hardness:
4
Specific Gravity:
5.24
Crystal System:
Trigonal
Name:
Named melanostibian by L.J. Igelström in 1893, for the Greek words describing its color (melano = black) and its composition (stibium = antimony). Renamed by P.B. Moore in 1967 to melanostibite along with the now discredited lamprostibian.
