Laurite is an opaque black, metallic ruthenium sulfide mineral with formula: RuS2.

It can contain osmium, rhodium, iridium, and iron substituting for the ruthenium.

[2] The sulfur is present as the disulfide ion, S2−2, so the ruthenium is in the Ru(II) oxidation state.

[4] It was discovered in 1866 in Borneo, Malaysia and named for Laurie, the wife of Charles A. Joy, an American chemist.

It occurs associated with cooperite, braggite, sperrylite, other minerals of the platinum group elements and chromite.
