A great piece of sodalite (hackmanite) with bright red-orange fluorescence under shortwave.
The material from this locality is probably the winner in the color-change department. We don't have much of this deeply tenebrescent material left.
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 LW fluorescence is knock-your-socks-off bright.
The animation shows the color change (tenebrescence) after exposure to longwave and shortwave UV.
