CROCOITE (Lead Chromate) from the Adelaide Mine in Tasmania, Australia. The very specific conditions for formation are unusual and it makes this mineral relatively rare. It was first discovered in Russia; however, the main source today is Australia. This mineral is very fragile, as the typical prismatic crystals are sometimes hollow.
