Brightly fluorescent both SW and LW. Most areas of green fluorescence is the typical uranyl activated mineral found on Ilimaussaq rocks. The material from this locality is probably the winner in the color-change department. Brightly fluorescent both SW and LW - the natural color deepens to a light pink upon exposure to LW UV (or obscure sunlight) and to a deep purple (almost black) after exposure to SW.
Upon exposure to SW UV the sodalite on this piece changes color to a deep purple - in seconds! Expose it to a bright white light (UV free halogen or LED spotlight held directly on the rock) and it reverts back to its natural color almost immediately.
The animation below shows the color change (tenebrescence) after exposure to longwave and shortwave UV.
