Jamesonite (also axotomous antimony glance, domingite, comuccite, pfaffite, grey antimony or feather ore) is a sulphosalt mineral, a lead, iron, antimony sulphide with formula Pb4FeSb6S14. With the addition of manganese it forms a series with benavidesite. It is a dark grey metallic mineral which forms acicular prismatic monoclinic crystals. It is soft with a Mohs hardness of 2.5 and has a specific gravity of 5.5 – 5.6. It is one of the few sulphide minerals to form fibrous or needle like crystals. It can also form large prismatic crystals similar to stibnite with which it can be associated. I
