Laurite has a Mohs hardness of 7.5 and a specific gravity of 6.99. It can contain osmium, rhodium, iridium, and iron substituting for the ruthenium.

Lorandite is a thallium arsenic sulfosalt with formula: TlAsS2. It was first discovered at Alzar, Macedonia in 1894 and named after E Lorand, a physicist at the University of Budapest. ...more on Wikipedia about "Lorandite"
The mineral marcasite, sometimes called white iron pyrite, is iron sulfide (FeS2). Marcasite is often mistakenly confused with pyrite, but marcasite is lighter and more brittle. Specimens of marcasite often crumble and break up due to the unstable crystal structure, and it is this crystal structure that is the main difference between marcasite and pyrite. Though marcasite has the same chemical formula as pyrite, it crystallizes in a different crystal system, thereby making it a separate mineral. In jewelry, pyrite used as a gem is improperly termed "marcasite". This is wholly incorrect, as marcasite is never used as a gem. ...more on Wikipedia about "Marcasite"
Miargyrite is a mineral, a sulfide of silver and antimony with formula: AgSbS2. Originally discovered in Germany in 1824 it has subsequently been found in many places where silver is mined. It usually occurs in low temperature hydrothermal deposits. and forms black metallic crystals which may show a dark red internal reflection. The streak is also red. ...more on Wikipedia about "Miargyrite"
Millerite is a nickel sulfide mineral, NiS. It is commonly found as radiating clusters of acicular needle like crystals in cavities in sulfide rich limestone and dolomite. It is also found in nickel-iron meteorites. ...more on Wikipedia about "Millerite"
Molybdenite is a mineral of molybdenum disulfide, Mo S2. Similar in appearance and feel to graphite, molybdenite has a lubricating effect that is a consequence of its layered structure. The atomic structure consists of a sheet of molybdenum atoms sandwiched between sheets of sulfide atoms. The Mo-S bonds are strong, but the interaction between the sulfur atoms at the top and bottom of separate sandwich-like tri-layers is weak, resulting in easy slippage as well as cleavage planes. ...more on Wikipedia about "Molybdenite"

Proust in 1804, after whom the mineral received its name. ...more on Wikipedia about "Proustite"

The mineral pyrite, or iron pyrite, is iron disulfide, FeS2. It has isometric crystals that usually appear as cubes. The cube faces may be striated (parallel lines on crystal surface or cleavage face) as a result of alternation of the cube and pyritohedron faces. Pyrite also frequently occurs as octahedral crystals and as pyritohedra (a dodecahedron with pentagonal faces). It has a slightly uneven and conchoidal fracture, a hardness of 6–6.5, and a specific gravity of 4.95–5.10. Its metallic luster and pale-to-normal brass-yellow hue have earned it the nickname fool's gold, but ironically enough, small quantities of actual gold can sometimes be found in pyrite. In fact, some auriferous pyrite is a very valuable ore of gold. ...more on Wikipedia about "Pyrite"
Pyrrhotite is an unusual iron sulfide mineral with a variable iron content: Fe(1-x)S (x = 0 to 0.2). The FeS endmember is known as troilite.
