Vauxite is known in many forms and colors from Siglo Veinte, and this piece shows an excellent blue color. The piece hosts several layered crystal groups of fine blue color bladed Vauxite which are sitting on a very thin layer of white Wavellite. It is very difficult to obtain Vauxite crystals on matrix from this locality, and as you can see, the Vauxite aggregates are simply gorgeous under magnification. The color is good for the species as well.
