Item Description

From a find in 2006. This piece is an attractive, very well crystallized, ridiculously rare, specimen consisting of small, bladed, beautiful blue color, radiating aggregates of Vauxite coated by with micro crystals Quartz on minor white Wavellite matrix. I have photographed the Vauxite crystals under high magnification 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 which was originally discovered along the Contacto and San Jose veins in this mine and first described by Sam Gordon and Mark Bandy.
