Argentiferous (Silver rich) Sphalerite Hampshire district, Tasmania, Australia 8cm x 6.2cm x 5.85cm Ex. Ward's (1875-1891) Ex. Michigan College of Mines No. 931 Ex. A. E. Seaman Mineral Museum #DM-20139

Description/Interesting Notes: An old time example of silver-rich argentiferous sphalerite from this historic Tasmanian locality!!! This specimen consists of a large mass of argentiferous sphalerite intergrown with galena (which is also quite likely "argentiferous")!!! Upon close examination, it is clear that this specimen hosts a significant amount of unidentified alteration products richly intergrown throughout it!!! There are both darkly colored "sulphide-like" alteration products present in cavities and surfaces covered with thin layers of somewhat waxy, tan colored material!!! This same material is also present outlining borders of interfgrown crystals in the matrix!!! Regardless of what is going on - this is a fantastic, old time example of silver ore from this historic silver mining district!!! This specimen is from the A.E. Seaman Mineral Museum and retains an old label from the Michigan College of Mines as well as an old Ward's lable (circa 1875-1891)!!! The pics hardly do it justice!!! Must be seen in person to be fully appreciated!!! Good luck and be sure to check out my other exciting mineral auctions on ebay!!!
