Unique Sorensenite - Fluoresces Yellow Under Longwave

As if sorensenite isn't unique enough - only found in one location in the world: Greenland - this piece is the first I have ever seen that is fluorescent a bright yellow under longwave UV (UVA). Sorensenite is a rare, beryllium-tin silicate only found in the Ilimaussaq Complex in Greenland, and only in a few areas. Normally it is nicely fluorescent a creme color (yellowish white) under shortwave and not at all (or maybe weakly) fluorescent under longwave. Usually found embedded in a tough analcime matrix and often found with uranyl activated green fluorescence. Some pieces will have minor sodalite associated, and really special pieces can be found with associated tugtupite.

The first two pics show closeup views under longwave and white light. The gallery shows the entire specimen under shortwave, longwave, white light, and a size pic.
