A 4.4 by 2.7 cm mass of mainly grey bismuth covered by a thin film of pinkish bieberite from an old classic Locality, Schlema, Schlema-Hartenstein District, Erzgebirge, Saxony, Germany
Bieberite was identified in volcanic cave settings for the first time at Irazú Volcano, Costa Rica and reported in 2018.[19] The mineral roemerite was identified at Island Mountain, Trinity County, California in the United States of America for the first time in association with bieberite along with pyrrhotite, claudetite, goslarite, fibroferrite, and morenosite and a description of the mineral from the site published in 1927.[20] The occurrence of bieberite at the Island Mountain deposit had earlier been recorded in 1923.[21] Uranium mineralization in the Cameron Area of Coconino County, Arizona was found to have bieberite as one of the cobalt mineral species in association with secondary uranium minerals formed through oxidation.[22]
