Bottle translucent green, very nicely formed Zanazziite to 1mm in clusters on Albite matrix with long, bladed Eosphorite. The old Don Cooke label identifies this specimen as Mg-Roscherite. I am assuming, based on Mindat photos, that it is Zanazziite. It is an excellent specimen.

Sorry about the blurry photos. This specimen comes from an old nickel-bearing copper mine discovered in 1732. The outer crust is said to be Zaratite, I suspect it is Retgersite. Hampson collected the specimen in 1944.

Zaratite is actually a questionable species and might be a mixture with Helleryite. There are unidentified light green platy crystals on this specimen.
