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 very pale green (nearly white) blades of Paravauxite which are coated by micro "sugary" Quartz which can be seen at the micro level. We have photographed the crystals with a close up macro lens 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. 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.
