Nuummite: The Sorcerer's Stone

Few stones carry a nickname as evocative as nuummite's: "the sorcerer's stone." Dark, almost black at first glance, it reveals flashes of gold, green, and blue as it catches the light — a shimmering effect produced by intergrown orthoamphibole and clinoamphibole minerals within the rock.

True nuummite takes its name from the Nuuk region of Greenland, where it was first described, and Greenland material is famous among geologists as some of the oldest rock on the planet — estimated at roughly 3 billion years old. The material we carry is Indian Nuummite, a similarly striking labradorescent stone from India that's widely sold under the nuummite name in the crystal trade for its comparable dark, flashing appearance, though it is mineralogically distinct from the ancient Greenland material.

Whatever its exact origin, nuummite's appeal is the same: a moody, almost galaxy-like surface that rewards slow turning in good light, much like labradorite but darker and more subtle. In metaphysical traditions it's sometimes called a "soul retrieval stone," associated with inner strength and shadow work.

We carry nuummite as tumbled stones and as polished cabochons ready for wire wrapping or jewelry settings. Browse our nuummite pieces to find one with flash that catches your eye.
