With the addition of [manganese](/source/manganese) it forms a series with [benavidesite](/source/benavidesite).<ref name=Handbook>http://rruff.geo.arizona.edu/doclib/hom/jamesonite.pdf Handbook of Mineralogy</ref> It is a dark grey metallic mineral which forms acicular prismatic [monoclinic](/source/monoclinic) crystals. It is soft with a [Mohs hardness](/source/Mohs_hardness) of 2.5 and has a [specific gravity](/source/specific_gravity) of 5.5 – 5.6.<ref>[http://webmineral.com/data/Jamesonite.shtml Webmineral data]</ref> 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](/source/stibnite) with which it can be associated. It is usually found in low to moderate temperature [hydrothermal](/source/hydrothermal) deposits.<ref name=Handbook/>

It was named for [Scottish](/source/Scottish_people) mineralogist [Robert Jameson](/source/Robert_Jameson) (1774–1854). It was first identified in 1825 in [Cornwall, England](/source/Cornwall%2C_England).<ref>[http://www.mindat.org/min-2072.html Mindat]</ref> It is also reported from [South Dakota](/source/South_Dakota) and [Arkansas](/source/Arkansas), US; [Zacatecas](/source/Zacatecas), [Mexico](/source/Mexico); and [Romania](/source/Romania).

Jamesonite generally has a very large number of synonyms, as well as regional and [trivial name](/source/trivial_name)s, which is unusual even for such noticeable minerals from a practical point of view. First of all, this is the already mentioned above domingite, comuccite, pfaffite, gray antimony or feather ore. In addition, jamesonite is also known by its English names: warrenite, wolfsbergite, [plumite](/source/plumite), rosellan, rosenite, sakharovaite, bleiantimonit, antimonial radiant glance, falkmanite... In the old German mineralogical literature the following names for jamesonite were also found: lumpenerz, stahlantimonglanz, spiessglasfedererz, chalybinglanz, zundererz.<ref name="kriv">''Krivovichev V.
