Nuummite Marquise Sterling Silver Ring; size 8

Nuummite Nuummite is a rare gemstone of volcanic origin, a unique mixture of anthophyllite and gedrite. These amphibole minerals metamorphosed into closely intergrown crystals of charcoal-gray to black, with beautiful iridescent flashes of gold at their transitions. Found primarily in Greenland, it was discovered in 1810 and named after its capital and largest city, Nuuk. One of the oldest minerals on earth at 3 billion years, nuummite is also known as “the sorcerer’s stone,” and is said to be a powerful grounding stone.
