Vauxite with Quartz and Childrenite

Item Description

From the find of 2007. This particular piece is a well crystallized, ridiculously rare, specimen consisting of small, bladed, pale blue color, radiating aggregates of Vauxite coated by with micro Quartz crystals on minor clay (probably decomposed Allophane) matrix. There are also some tiny brownish-tan Childrenite on the specimen as well. I have photographed the crystals under the microscope 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 of the mine in 1922 and first described by Sam Gordon and Mark Bandy.
