Greenland sodalite comes in all colors. This piece is a very bright piece under both SW and LW.
This piece of fluorescent sodalite is very tenebrescent. The sodalite on this piece changes color when exposed to UV (SW), darkening to a purple as shown in the GIF below - a unique hue compared to other Greenland sodalites. Under LW the bright orange fluorescence is unmistakable.The analcime has a dim magenta fluorescence. At the upper left corner is an area of violet fluorescence from an unknown mineral. Our first thought was leucophanite but the lack of fluorescence midwave makes us doubt that.
