Hi,
Crystallizing like an iron rose (Eisenrose), a very rare cervandonite- (Ce)
What is the nature of the (pseudo) hexagonal crystals ?

Hi Roger,

I think those crystals are a member of the mica group, possibly muscovite. In several samples I have got from the same area it is possible to see similar crystals, both as clear crystal as yours or as dark, almost black, crystals (probably biotite) in sizes up to a couple of mm.

Best regards,

Felix
