I've just grabbed my blacklight and gone over the gems I have seeing as its dark and all. I have managed to pick out 3 that fluoresce orange, none others do. Of the three one is clear, one is yellow and the other is honey/red. The clear has the 'classic' sapphire crystal shape and is a half decent size. I have no idea where it came from though which is annoying - but it looks like I have a decent cuttable white sapphire!
I'll have a better look in the sunlight tomorrow and get some pics.
Nugget, I'm back in the hunter Tuesday if you want to meet up and cast my blacklight over your stone??
