A deeply tenebrescent piece of tumbled tugtupite and black arfvedsonite with interesting patterning.
A very rare stone, the name tugtupite is derived from the locality where the mineral was first found in Greenland. Tugtupite is also referred to as Tuktu, a named derived from the Greenlandic Inuit word for reindeer (tuttu) and means “reindeer blood.”
For ages, the inuit of Greenland have understood the power of tugtupite. Legend has it that lovers can cause the stone to glow fiery red just from the heat of their romance. The brilliance and vibrant colors announce the intensity of their love.
How to tell the tugtupite you purchase is real:
1. It will glow a bright red under shortwave UV light or a salmon-orange under longwave UV light
2. No fluorescent lights? It will darken upon exposure to sunlight (sometimes, only slightly depending on how much tugtupite is in the stone) this phenomenon is called “tenebrescence”
3. It is phosphorescent (it briefly glows after exposure to strong UV light)
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.
