Description:It is unbelievably rare to find specimens of Vauxite with this color. This specimen is a very well crystallized, OUTSTANDING blue color, ridiculously rare specimen consisting of radiating crystal aggregates of Vauxite on a layer of decomposed Allophane / clay matrix. I have photographed the crystals under high magnification to show that they are truly terminated crystals and not just a blue mass. I must point out that these crystals of Vauxite show the most electric neon blue color that I've seen for the species, but it appears that the rich color is acutally due to a micro coating of transparent Quartz on top of the Vauxite. It is very difficult to obtain any specimens of this incredibly beautiful phosphate, but this color is simply unheard of. This piece is from the 2008 find at 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. You will not find better color Vauxite anywhere ! Valued in the inventory at $1250.
