Collection grade, fluorescent, tenebrescent and phosphorescent Sodalite var Hackmanite (bright orange-pink in long wave, purple-white in short wave) with Dolomite (pale blue in short wave) mineral specimen (64ct).
This Hackmanite specimen demonstrates bright orange-pink fluorescence under the long wave UV light, very sharp daylight tenebrescence (colour change is very noticeable in a few seconds after exposure to sunlight), and phosphorescence in the short wave UV light. Purple-white fluorescence in the short wave UV light is in fact very bright phosphorescence overpowering usual purple-red fluorescence. The phosphorescent afterglow is much stronger after illumination with a focused beam short wave UV light and is well visible for a few minutes in complete darkness. Watch the video for more details. Camera is not able to capture long lasting afterglow the same way human eye can.
When left in dark or indoors for prolonged duration (hours to days) the purple colour will fade! However, it is very easy to restore the deep purple colour by exposing the specimen to UV light, meaning the colour change is reversible.
