This is an unusual specimen from an unusual locality! It shows a couple of hemispheres, the largest 9mm diameter, of acicular, light blue aurichalcite in a vug, mostly lined with rounded smithsonite crystals. The smithsonite is colourless and sharp, albeit small. The matrix is very dense and I expect it is composed of smithsonite. Nice!
