Sodalite from Greenland, found off sodalite beach

This is one of the brightest varieties of sodalite from the Ilimaussaq Complex in Greenland. It is colored pea-green in white light and fluoresces a very bright yellow/orange under both longwave and shortwave. These pieces are not normally tenebrescent, but this piece is - resulting in a slightly darker, rusty orange color under SW (once the tenebrescence sets in). The animation shows this color change after exposure to SW. The green fluorescence is uranyl activated.
