Tsumeb mine is renowned as the premier locality for crystals of Zincolivenite - the intermediate species between Olivenite and Adamite in composition. The crystals are known to range from: glassy, vibrant acidic green, in elongated, bladed to wedge-shaped crystals; opaque, greyish-green blocky wedge-shaped crystals; to opaque, leafy green rounded, to almost botryoidal forms. This large miniature Zincolivenite from the famous, generations-old Weyand Collection in Tsumeb town is predominantly the middle form, as opaque, small wedge-shaped crystals encrusting matrix. The crystals are mint-green in colour but also show zonation, with darker, pearlescent, somewhat naturally etched surfaces. Associated with these is a darker, mossy-green mineral whose identity is not known, but one possibility is Olivenite. Although small, the Zincolivenite crystals are really well-formed and look beautiful under magnification.
