Translucent milky-white scalenohedral crystals of Smithsonite form a spiky dense triangular cluster on a sooty matt black matrix of botryoidal Coronadite. From the Broken Hill Proprietary mine, New South Wales, Australia, the Smithsonite forms ant-egg crystals to about 5 mm and a few larger and more rounded crystals to about 8 mm, all of which contrast well against the Coronadite, a lead-manganese oxide.
