This is a perfect sample of color changing sodalite called hackmanite with a small vein of rare tugtupite from Greenland.
Under longwave the hackmanite will fluoresce an intense orange, the tugtupite will fluoresce red under shortwave (see photos). After uv exposure the hackmanite will turn purple and after a few hours the hackmanite will turn white again.
