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.
