Franckeite with Wurtzite (rare combo) (ex Josef Vajdak)

Item Description

An incredibly rare specimen of the iron tin lead antimony sulfosalt, Franckeite from the historic San Jose Mine in Oruro, Bolivia. Most people associated Franckeite with this locality, and while the best pieces of this species are found at this mine, it's actually not the type locality. It IS the type locality for the associated mineral on this piece, which is Wurtzite. Now I can say that this is likely the first and only piece that we've had to offer in the auctions featuring Franckeite with Wurtzite together from this mine. You'll notice that the specimen is comprised of somewhat radiating aggregates of bladed, grey Franckeite with a good metallic luster, but you have to look very closely for the Wurtzite, which is admittedly small, but beautiful. There are a few gorgeous "rosettes" of greenish colored hexagonal crystal groups of Wurtzite that can be found on the specimen, and we've photographed them to the best of our ability to show their quality. A really special and good quality specimen of this classic material. This particular piece was mined in the late 1970s - early 1980s. The piece comes with a label from rarities expert Josef Vajdak. If you collect sulfides/sulfosalts, rarities or minerals from the type locality, do NOT miss out on this one! Priced at $800 in the inventory.
