fluorescent sodalite

A museum quality piece of deeply tenebrescent hackmanite. Brightly fluorescent under all wavelengths, the hackmanite also displays some phosphorescence which is unusual. Most areas of green fluorescence is the typical uranyl activated mineral found on Ilimaussaq rocks. First it’s very tenebrescent, darkening to a purplish hue after exposure to shortwave UV light. The striking tenebrescent purple hue against the white matrix provides a perfect example of tenebrescence. Combine this with the size of the specimen and you’ve got a superb piece for a collection.
