An obscure specimen of Molybdosodalite (with vugs) from Naples Italy. The clear crystals appear to be NF and are just reflecting the glow of the sodalite. They are very delicate. Pictures are LW, SW, Natural using a 60mm macro lens at F32 ISO 100. Notice how one area is non responsive to LW, but does glow in SW. The SW response is not particularly bright.
