A rich and showy thumbnail specimen featuring a bright mass of renierite intergrown with a suite of grey, black, and purplish sulphides, likely including briartite, tennantite, and bornite. The renierite is easily distinguished by its iridescent metallic pinkish-bronze colour, standing out vividly against the darker sulphide matrix. The piece is dense and visually striking, offering an excellent representation of this very rare germanium-bearing sulfosalt.
The specimen comes from the type locality for renierite, the well-known Kipushi Mine in the Democratic Republic of Congo, a major Zn-Pb-Cu deposit located southwest of Lubumbashi near the Zambian border. This deposit is notable for its complex mineralization, including a wide range of sulphides enriched in elements such as germanium, gallium, molybdenum, tungsten, and vanadium. Renierite occurs in distinct zones within the mine, notably between the 275–400 m and 725–775 m levels. Originally worked as an open pit and later as an underground operation, the mine was inactive for nearly two decades before reopening in 2022. This specimen comes from the collection of Robert Yeoman and represents a fine example of a rare species from its classic type locality.
