Jordanite is a sulfosalt mineral with chemical formula Pb
14(As,Sb)

23 in the monoclinic crystal system,[2] named after the German scientist H. Jordan (1808–1887) who discovered it in 1864.

Lead-grey in colour (frequently displaying an iridescent tarnish), its streak is black and its lustre is metallic. Jordanite has a hardness of 3 on Mohs scale, has a density of approximately 6.4, and a conchoidal fracture.[2]
