[QUOTE="Explorer385, post: 162773, member: 1849"] Hi all, I have 20 sapphires and zircons found at Grabben Gullen away being cut at the moment. Will post photos when I get them back. I have lots and lots of rough that looks black but some of it could be blue. I check them using a magnifying light on a mirror with either a 500 watt work light shing on the mirror or a 40 watt led work light on the mirror. What do others use to check for transparency? Sorry mods if this is not appropriate for this particular thread. Terry [/QUOTE]
