Vauxite
Here we have a remarkable, well crystallized, superb venetian blue color, very rare specimen consisting of radiating crystal aggregates of Vauxite. The piece is actually a thin layer of Vauxite which may have formed on top of some kind of clay (perhaps decomposed Allophane), which dissolved and left this "lace"-like crust of superb blue color Vauxite behind. It is very difficult to obtain any specimens of this incredibly beautiful phosphate. This piece is from the type locality for this material which was discovered along the Contacto and San Jose veins in this mine and was first described by Sam Gordon and Mark Bandy.
