EYE-VISIBLE crystals of sternbergite line 80% of the top ridge of this remarkable old specimen, which I received at Tucson in exchange from Bill Pinch. It is a large and very rich specimen for this rare silver species! The crystals are to 1 mm (though most are smaller than that and are sparkly sub-mm crystals), and although the species gets bigger it is but rarely and seldom in any large clusters as we see here. There are literally hundreds of crystals here and the piece could easily be chopped in portions for sale at higher prices in total. Comes with old label from Schortmann's Minerals (1940's). 13 x 7 x 3.5 cm
1.5 x 1.0 x 0.9 cm. Sternbergite is a rare silver, iron sulfide and this excellent, rich thumbnail is from the Type Locality - Jachymov, Bohemia, Czech Republic. Scintillating to moderate-lustre, burnished, violet-blue sternbergite blades and crystals comprise this thumbnail, which is solid sternbergite. Eye-visible crystals of sternbergite are rare and the large blade on the left side is 8 mm on this remarkable old specimen.
