Antique specimen loaded with tiny micro crystals of tabular, striated Sternbergite and Argentopyrite. I have to say though the two are hard to tell apart. Amongst these crystals are a few unknowns including greenish spheroidal crystals and radial fibrous tan crystals. Photos do not do it justice. Not the two older labels, one from Parnau and the is a Maucher label.
