Nuummite is usually black in colour and opaque. Other common minerals in the rock are pyrite, pyrrhotite and chalcopyrite, which form shimmering yellow bands in polished specimens.

The rock was first discovered in 1810 in Greenland by the mineralogist K. L. Giesecke. It was defined scientifically by O. B. Bøggild between 1905 and 1924. True Nuummite is only found in Greenland. Due to its iridescent nature, this rare stone is sought after by gemstone dealers, collectors and those interested in the esoteric.
