Item Description

This piece is a remarkable, very well crystallized, ridiculously rare, specimen consisting of small, bladed, beautiful blue color, radiating aggregates of Vauxite coated by with very pale green (nearly white) blades of Paravauxite on white Allophane matrix.  TINY spots of golden Childrenite can be seen on the piece as well.  We have photographed the crystals with a Canon MP-E 65 mm macro lens 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 these days. 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, because they only come from one mine in the world in good display specimens.
