Item Description

From the find of 2007, this is another great discovery for this locality. This particular 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 of Quartz on minor clay (probably decomposed Allophane) matrix. There are also some tiny spots of brownish-tan Childrenite on the specimen as well. I have photographed the 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 on the market. This piece is from the type locality for Vauxite which was originally discovered along the Contacto and San Jose veins in this mine and first described by Sam Gordon and Mark Bandy. Enjoy!
