Description:Here we have a remarkable, very well crystallized, great blue color, ridiculously rare specimen consisting of layered / radiating crystal aggregates of Vauxite. I have photographed the crystals under the microscope to show that they are truly terminated crystals and not just a blue mass. It is very difficult to obtain any specimens of this incredibly beautiful phosphate, but this color is hard to find. This piece is from the type locality for this material which was originally discovered along the Contacto and San Jose veins in this mine and first described by Sam Gordon and Mark Bandy.
