An incredible hackmanite specimen with unusual minerals and many colors. This specimen has a mix of orange fluorescing ussingite, polylithionite, green chkalovite and bright fluorescent sodalite. There is a beautiful light blue fluorescence under shortwave and midwave that is unknown, we've not seen it before. We're constantly finding new minerals from Greenland. Its strongest under midwave UV light and possibly slightly phosphorescent.
We found very little of this type of material.
Ussingite from Ilimaussaq has three possible states: it can be non-fluorescent, fluoresce orange just like sodalite, or can fluoresce green. When ussingite fluoresces a more common orange, it is due to being mixed with sodalite. It is slightly tenebrescent where the sodalite has mixed with the ussingite.
"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.
