I found almost no information from searching Google, Someone mentioned it might be Fluorite. I simply don't know where else to look for an answer and so I am asking you.
When I was a child, my parents traveled with me to Egypt and there, they bought me a little scarab beetle carved of some stone, about 5 cm long, 2 cm width and height. The stone is whitish and translucent and glows green in the dark (for some time). I only remember that it might (just a speculation) have been in Luxor in an Alabaster workshop. But, according to online sources, Alabaster is not supposed to glow in dark, so what is it then? Can you please tell me?
The phosphorescence [nb, earlier version said 'fluorescent'] is really weak and doesn't last longer than 5-10 min so I am sorry for a bad photo, just couldn't make it better.
