Bright cherry red fluorescing tugtupite on an analcime matrix mixed with uranyl green makes for very attractive patterning. Very phosphorescent and tenebrescent.
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.
Prior to our explorations in 2001-2011 tugtupite was really only available from the Kvanefjeld locality, and only known from a few other places. Since, pieces from the Taseq Slope locality have become popular with collectors - and more available. This area has become the most prolific supplier of tugtupite to the fluorescent mineral market, and has been given the nickname "Taseq Tugtupite”. We should note that, unlike hackmanite from Greenland, tugtupite is not quick to fade once it has changed color. Pieces might take days or even weeks to fade completely.
"Red" Sodalite (Hackmanite) - Deeply Tenebrescent Greenland Mineral
Red sodalite is named for the color it takes on when exposed to sunlight; it is nicely tenebrescent under longwave UV. Under shortwave UV the color deepens, in seconds, to almost black in some areas.
