About Viridine
Formula:
(Al,Mn3+)2SiO4O
Colour:
Grass green
Lustre:
Vitreous
Name:
Named after the Latin "viridis", meaning "green".
A Mn3+-bearing, green variety of andalusite.
Compare kanonaite, Mn3+Al(SiO4)O.
Synthetic viridine coexists with Mn-poor orange-yellow Mn-bearing kyanite (Abs-Wurmbach & Langer, 1975).
