Kobellite is a gray, fibrous, metallic mineral with the chemical formula Pb₂₂Cu₄(Bi,Sb)₃₀S₆₉. It is also a sulfide mineral consisting of antimony, bismuth, and lead. It is a member of the izoklakeite – berryite series with silver and iron substituting in the copper site and a varying ratio of bismuth, antimony, and lead. It crystallizes with monoclinic pyramidal crystals. The mineral can be found in ores and deposits of Hvena, Sweden; Ouray, Colorado; and Wake County, North Carolina, US. The mineral was named after Wolfgang Franz von Kobell (1803–1882), a German mineralogist.
