I think a visit to a jewler might help. I am close to the jewelry quarter but on the wrong shift to visit. If I do get chance, I will ask and let you know any results.

If it is tell me to get lost. Has any one any experience in putitng small holes through quartz? I've a daughter rather hoping I can drill through a piece of ametrine nearly 1cm thick so she can have a pendant. I'm thinking in terms of emigrating but if that doesn't work then diamond drills to be bought at Donington and lots of spit as lubricant but thoughts welcome. MODEL ENGINEERING DISCUSSION LIST.
