Nuummite is an ancient and rare metamorphic stone prized for its dark, almost black base with shimmering flashes of gold, copper, blue, and green caused by iridescent anthophyllite and gedrite crystals. It is found exclusively in Greenland and is considered one of the oldest minerals on Earth, dating back over 3 billion years.
