Nuummite is in the Orthorhombic crystal system in the family of silicates. It is a metamorphic stone, which means that it is formed as a result of the transformation of existing rock.
The main make up of Nuummite is actually Gedrite, a lithium amphibole, and Anthophyllite, a magnesium iron silicate. It also contains lesser amounts of Pyrite, Pyrrhotine and Chalcopyrite. It’s coloring can range from light gray to black with iridescent yellow, blue, red, green, gold and/or violet flecks. The flashes of color we see comes from its structure (thin, alternating fibrous layers) much like what we see in Labradorite.
Nuummite was discovered in 1982, so it is a fairly new gemstone to the metaphysical world. Its name, through translation, means “from Nuuk”, due to the fact that it was found in the Nuuk region of Greenland. Although only recently discovered, it was actually formed more than three billion years ago, and is now known as some of the oldest stone on earth.
Nuumite is also known by other trade names as the Shaman’s Stone, Sorcerer’s Stone, or Magicians Stone.
