"Taseq Tugtupite" has become one of the more popular varieties from Greenland. We found this material on our 2nd visit. Most pieces occur as veins in a matrix of analcime crystals. A select few massive habit pieces were found.
Tugtupite is a very rare mineral - found in only three places around the world (Kola Russia, Mt St Hilaire, and Greenland). Pieces from Greenland are the most sought after due to coverage, size and brightness. This material is from the Taseq Slope. Bright cherry red tugtupite with a very bright rare variety of lithium mica - polylithionite. The matrix is albite (or possibly analcime – an area of confusion) which fluoresces a dull magenta SW and a dull bluish/white LW.
First, an animation showing the difference between the UV flashlight we recommend (365nm filtered UV flashlight) versus unfiltered 395nm UV flashlights we see many folks carrying around at shows. So. much. visible purple light. We selected a bunch of rocks as a demonstration. Took pictures of them under his flashlight without the filter and then with the filter.
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.
