Nuummite Gemstone Information
About Nuummite - History and IntroductionNuummite is the trade name for a rare black gemstone with flecks that show an iridescent play of color. It is a metamorphic rock, which means that it is formed as a result of the transformation of existing rock. The main constituents of Nuummite are gedrite and anthophyllite, with lesser amounts of pyrite, pyrrhotine and chalcopyrite. Nuummite's iridescent play of color is due to its lamellar, fibrous structure (alternating fibrous layers). Nuummite was discovered in the early 1980s, so it is a fairly new gemstone. Its name means "from Nuuk", because it was found in the Nuuk region of Greenland. Although Nuummite was only recently discovered, it was formed more than three billion years ago, so it is also known as the oldest rock on earth.
Nuummite is quite a unique gemstone and can be recognized by its dark body color interspersed by iridescent flecks that give it its play of color. Nuummite is found in the Nuuk region of West Greenland.
