Well formed crystals of tricoloured Zincolivenite with Malachite from the Tsumeb Mine, Namibia. Crystals of Zincolivenite measuring to 0.7cm have formed as single crystals and intergrown on a reddish Goethite/Hematite matrix. The Zincolivenite was evidently first deposited as gemmy to translucent yellow crystals, covered by green Zincolivenite, and a final phase of pastel green Zincolivenite. The Malachite forms as deep green drusy botryoidal cluster at the central area of the specimen. A small amount of dark olive green Olivenite is also present.
