Diamond Tipped Drill

Can I (and/or how do I) drill a hole in an emerald?

I have a 28 carat Brazilian emerald which I would like to drill a hole in to hang inside a window. I do not want to apply an adhesive to detract from its visual appeal. I have asked the local jewelry store but they are unable to drill me a hole in it. I have only regular drill bits, not diamond tipped. I have a power drill to use, but not an expensive drill press. If I drill with the bit underwater, will it aid me? The value of the emerald is low because it is opaque, so I don’t care that much if anything happens. Then again, I don’t want it to get cracked if there is a high probability of this occurring. For your information, the hardness of this gem is roughly between 7 and 7.5 on the hardness scale.

It would be absolutely fatal to attempt to drill your emerald with a DIY type drill – you will end up with a pile of broken bits, even if you fit a diamond drill bit it will not work. I am sure that there are some local lapidary clubs near you somewhere and I am certain that you will find a member who will be only too glad to help you out.
Good luck.
