This is significant for Tsumeb! Totally covering its hefty, limonitic matrix, is a drapery of chatoyant, velvety, dark green malachite. It has grown in large botryoids reaching 4.0 cm across. The chatoyance effect is very noticeable here, with seemingly shifting dark and light spots as you twist it in the light. Few large malachite specimens of this caliber from Tsumeb would be available, especially in such good condition. It is an important locality piece and a nice dose of color to add to any Tsumeb suite, though the mineral may be common from other places.
