Tsumeb mine is well-known for impressively large Anglesite (lead sulphate) crystals, but with their size comes frosting and opaqueness. This large toe-nail sized cluster of intergrown Anglesite crystals is a classic example, with all of the crystals white and frosted, but nicely formed orthorhombic blades reaching up to 9 mm in length, and with some twinning evident.
