SOLD

This particular piece is a remarkable, very well crystallized, very rare specimen consisting of small, bladed, beautiful, blue radiating aggregates of Vauxite coated by with tabular blades of greenish-white Paravauxite on minor clay (probably decomposed Allophane) matrix. There are also some very tiny spots of brownish-tan Childrenite on the specimen 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.
