Paravauxite on Vauxite

Item Description

This piece is a remarkable, very well crystallized, ridiculously rare specimen consisting of parallel growth blades of greenish Paravauxite on small, radiating, beautiful blue color aggregates of Vauxite on white clay (probably decomposed Allophane) matrix. I have photographed the Vauxite crystals under the microscope to show that they are truly terminated crystals and not just a blue mass. I have also photographed the Paravauxite crystals under the microscope as well. It is very difficult to obtain any specimens of these incredibly beautiful phosphates 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. From the find of 2011.
