A beautiful, small cabochon of authentic Greenland nuummite that contain a glossy, rich, black color.
Nuummite is a gemstone formed from a mixture of two minerals from the orthoamphibole group: anthophyllite and gedrite.
Geologically speaking, nuummite is of volcanic origin and was formed about 3 billion years ago. Subsequent influences on the rock (metamorphism) have given rise to the striking mixture of crystals which gives nuummite its unique appearance
A major component of rock collecting (for us) is simply getting out in nature. A buddy dragged us out to a very remote area here in middle Tennessee to hunt for fluorescent green agate. Since we consider ourselves pure "Glow Hounds" we weren't anticipating any glow rocks, just the beauty of the area, but we brought our UV lights anyway.
