These exceptional and uniquely colorful silver species specimens were collected in 1977 by Joe Weinholtzner at a remote location. Rumour (and truth as it turns out!) had it that nearly all were stored in a coffee can at the time, and kept that way for decades. Not the best packing job for a collector...The polybasite crystals, of which this is a sharp and robust examples, have been previously very scarce on the market in any size. Most are thin plates, whereas this is a robust, 3-dimensional cluster. The specimens feature a very attractive purple/blue/red/green iridescence, which sets them off from other worldwide localities for these species (both the polybasite and stephanite from here have this coloration). The mine is defunct and despite attempts no more have been found here in 30 years now. The color is spectacular: a metallic mix of iridescent purple, red and blue hues (much more obvious in person than the pictures indicate) .
