A beautiful, very rare greenlandite sphere.
Greenlandite has been used as a gemstone in Greenland for many years, justly marketed as “the world’s oldest gemstone”.
Greenlandite was discovered in the 1960s in Isukasia north of Nuuk. The geological environment in which greenlandite was formed was in the order of 3.8 billion years old. This means that we are talking about one of the earths oldest formations!
Geologically speaking, the rock consist of quartzite with a large content of a green minerals - fuchsite - evenly distributed throughout, giving the stone a fresh green color. Greenlandite is a hard mineral, often translucent with a metallic inner glow derived from its many spangles. This type of stone is also known, in the jewelry trade, as aventurine quartz.
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.
