Vauxite with Paravauxite (rare)

Item Description

This piece is a remarkable, very well crystallized, ridiculously rare, specimen consisting of small, bladed, beautiful blue color, radiating aggregates of Vauxite associated with small tabular blades of pale green Paravauxite on minor clay (probably decomposed Allophane) matrix. Additionally micro "sugary" Quartz and tiny brownish Childrenite can be seen at the micro level. I have photographed all of 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 this incredibly beautiful phosphate and to find 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 beautifully crystallized specimens of Vauxite and Paravauxite together from Bolivia like this one.
