Item Description
From the find in 2008, this is another great discovery for this locality. This particular piece is a remarkable, very well crystallized, ridiculously rare, specimen consisting of small, bladed, beautiful INTENSE blue color, radiating aggregates of Vauxite on minor clay (probably decomposed Allophane) matrix. We have photographed the Vauxite crystals with a Canon MP-E 65mm macro lens 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 for Vauxite and Paravauxite which were originally discovered along the Contacto and San Jose veins in this mine and first described by Sam Gordon and Mark Bandy. It is so unbelievably rare to find good size, beautifully crystallized specimens of Vauxite and Paravauxite together from Bolivia like this one. Priced at $400.
