Wow, I would say something in the radium spectrum. So here's the rub. You say it glows for five days. Most rocks only glow for moments after being removed from a light/heat source. So unless there is a source of one or the other or it is very radioactive something is up. Thing is it could be very cool and unique and it could be dangerous.. Take it to a rock shop. See what they say. They may have a small geigercounter which measures radioactivity. Some phosphorescent rocks flouresce in ultraviolet light..There are numerous rocks which will glow for a few moments, calcite, flourite, colemanite, celestite, willemite, sphalerite...

The stone is like a potato on the outside. Completely stops glowing after 5 days without light source. I will have it checked with a geiger counter. Thanks for the tip.

With further research I have found these for sale on a website and they call it a form of fluorite called Nunatak Bruiachite, whatever that is!
