Plagionite is a rare lead, tin sulfide. This incredibly rich specimen is relatively large and of high quality for this famous old find....probably dating back over 50 years to the Mark Bandy era in Bolivia. It features sharp metallic crystals to 9mm in size, in an interconnected cluster. For crystal size, and robustness, and overall richness of the piece, this is one of the better surviving examples, I think we could say. From the private collection of miniature-sized rarities of dealer Lawrence Conklin, I was threilled to obtain this and so startled by the quality I had it checked out to be sure.
ex. American Museum of Natural History
This is a MAJOR specimen of this very rare lead-antimony-sulfide species with crystals to 1 cm, and is overall 4 cm long when laid out in longest dimension. It hosts a beautiful ridgeline on matrix of these very rare, large plagionite crystals! This specimen has crystals above the maximum reported for the locale (see Lapis: Bolivia); and they really are quite showy in person. Other micro-mineralization, not analysed, is also present. This is AMNH number 33017 and carries a label from the mid-1900s from the Museum. It was exchanged out of the museum in the 1970s and ended up in the private collection of dealer Lawrence Conklin. Such a piece from the other great locality for the species in Germany would cost 5000, or more. Yet, from Bolivia it is more rare in reality, if not price.
