I recently seen some glowing rocks at a museum in Sarnia, ON, at the Stone and Bones museum. They had different types of UV light to show various rocks glowing. It was so amazing and beautiful!
Some rocks flouresce or glow. These rocks under UV light rays emit a glow or light.
Fluorescent rocks include fluorite, calcite, gypsum, talc, ruby, opal, agate, quartz, and amber.
Diamonds also are flourescent under UV light.
Minerals and gemstones are most commonly made fluorescent or phosphorescent due to the presence of impurities.

Scheelite, or calcium tungstate, emit a blue glow under short-wave UV light.
Flourite or calcium flouride, usually flouresces blue, but some specimens emit red, white, green or yellow color, under short and long wave UV light.
Scapolite is found in short or long crystals, and emits an orange or yellow color, and some emit red, although rarely.
The colors of the rocks under regular light is pink or purple and yellow or orange.
Other rocks that glow include:
Willemite - bright green glow or phosphoroscent;
Calcite
Autunite - this yellow-green colored rock fluoresces under black light
Gypsum
Eucryptite
