Description
This is classic and old-time material from the tin & tungsten deposits of Zinnwald in Erzgebirge, Saxony. Here we have a highly lustrous, jet-black, crystal of Wolframite accompanied by silvery bladed "Zinnwaldite", a member of the mica group, more precisely a series between Siderophyllite and Polylithionite. Despite not absolutely perfect, this is ideal material for the collector of old classics.
