This specimen of vauxite is from its type locality. The host rock looks like a thin shell of quartz, coated with a thin layer of pale vauxite crystals. If it weren't for the pale blue color, I would have suspected that these crystals were paravauxite. Actually, the vauxite appears to be coated with more of this mineral, a sparkly druze of square prismatic crystals with a slanted termination. The bulk of the vauxite is in the form of masses of lovely blue crystals whose form cannot be identified (all of the identifiable crystals appear colorless).
