Description:From the recent find in 2009, this is great discovery for this locality. This particular piece is a remarkable, very well crystallized, ridiculously rare, specimen consisting of small, bladed, beautiful rich blue color, radiating aggregates of Vauxite associated with tabular blades of very pale green Paravauxite and very minor brownish Childrenite on minor clay (probably decomposed Allophane) matrix. I have photographed the Vauxite and Paravauxite 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 this incredibly beautiful phosphate and to find all two "Vauxite" species together on one piece is fantastic. This piece is from the type locality for Vauxite and Paravauxite which were originally discovered along the Contacto and San Jose veins in this mine and first described by Sam Gordon and Mark Bandy. It is so unbelievably rare to find good size, beautifully crystallized specimens of Vauxite and Paravauxite together from Bolivia like this one.
