[QUOTE="Heatho, post: 26367, member: 487"] Well sort of, UV light will make some stones fluoresce, do a google for "fluorescent gemstones" and you should get a few good pics come up. Zircon I think will fluoresce yellow or a creamy colour, diamonds will fluoresce a bluish colour depending on quality, the best and clearest diamonds will not fluoresce. Not sure about Tourmaline but the led lights may be making them fluoresce yellow, will know for sure when my torch arrives. Also to add to this, long and short UV will fluoresce some stones a different colour. I'm actually getting it more for night time gem hunting, especially for Zircons, only very few Sapphires will fluoresce. Dunno if it will work, but worth a try. [/QUOTE]
