• The name Nuummite which means "derived from Nuuk" in Greenlandic was given to the amphibolitic rock type which was found by the geologist Peter W. Uitterdijk Appel in 1982, near Nuuk (Godthb). Appel considered first the name nuukite, but renamed it to Nuummite, which in Greenlandish means "from Nuuk".
• Nuummite is usually black in colour and opaque. It consists of two amphiboles, gedrite and anthophyllite, which form exsolution lamellae that give the rock its typical iridescence. Other common minerals in the rock are pyrite, pyrrhotite and chalcopyrite, which form shimmering yellow bands in polished specimens.
• Nuummite is light-gray to almost black with flecks of iridescent color ranging from yellow to golden, green to metallic blue, and reddish to violet. The flecks can range in size from a few millimetres long to several centimetres long. Formula: (Mg2)(Mg5)Si8O22(OH)2; Mohs Hardness: 5.5 to 6; Colour: Dark gray, brownish-black. Blue, golden yellow and reddish iridescence.
