A sphere of our very gemmy sodalite hackmanite material. This gem sodalite is blindingly bright under all wavelengths - midwave, shortwave and longwave with incredible tenebrescence. You won’t find many Greenland sodalite spheres on the market.
The sodalite on this piece changes color when exposed to UV (shortwave), darkening to a grape purple (almost black) as shown in the GIF below - a unique hue compared to other Greenland sodalites. Under longwave, the bright orange fluorescence is unmistakable.
Under midwave, there are some dim spots of violet which could possibly be leucophanite.
