Item Description

Here we have an attractive, very well crystallized, ridiculously rare, specimen consisting of beautiful blue color, radiating crystal aggregates of Vauxite with minor very pale green Paravauxite on white Wavellite on matrix. I have photographed the crystals under the microscope to show that they are truly terminated crystals and not just a mass. It is very difficult to obtain any specimens of these incredibly beautiful phosphates. This piece is from the type locality for this material which was discovered along the Contacto and San Jose veins in this mine and was first described by Sam Gordon and Mark Bandy. It is so unbelievably rare to find matrix specimens of Vauxite from any locality in Bolivia or anywhere else in the world.
