About GanomaliteHide

Formula:
Pb9Ca5Mn(Si2O7)4(SiO4)O
Colour:
Greyish white
Hardness:
3
Crystal System:
Hexagonal
Name:
Named in 1876 by Nils Adolf Erik Nordenskiöld from the Greek γανωμα = brilliance due to the mineral's adamantine luster.
The Mn (or rather Ca5Mn-) analogue of wayneburnhamite.
Fresh ganomalite displays a high lustre but surfaces turn dull white with time.
