Here is an unusual one! This is a very rich specimen of hydrozincite that, in places is botryoidal, where open spaces exist and massive in others. Where there are open spaces, there are tiny, colourless, prismatic crystals on the botryoidal hydrozincite, perhaps hemimorphite. The hydrozincite fluoresces a bright blue-white colour, perhaps not quite as turquoise as in the picture but an intense blue-white that is characteristic of hydrozincite. Displays well!
