Dear cjensen,
Other folks know more than I do about drilling (OK, guys, that's your cue to post your tips)... :icon_18: Here's a quote from an earlier thread, though, written by our owner Russ:
"Most rock shops (see yellow pages under Lapidary) carry small diamond bits. They are a thin wire with diamond powder glued onto or sintered into the wire. We can special order them but I think you can find them locally. Nearly all the Lapidary dealers on line carry them. Ebersole, Eloxite Corp, cyberrockhound.com, Rio Grande, Rock Haus Intnl, Diamond Pacific, mytoolstore.com, etc all should have them.
Diamond bits need to be run wet. That is, you need to put the bit in a Foredom, Dremel or other small drill and submerge the object in a shallow tray of water. I usually move the bit up and down so the water can touch the bit and take the heat from the bit. Using water as a coolant keeps the diamond from burning off the bit and keeps the opject being drilled from overheating and cracking.
I put a small piece of brittle styrofoam (the kind x-mas balls are made from) in the bottom of the tray and rest the object on it, This keeps me from drilling through the bottom of the tray. (Experience, eh?)
Here's a link to an article on this using a big drill press:

My setup with a Dremel in a tiny Dremel drill press stand is somewhat smaller.
Hope this helps."
But also, what about wire-wrapping? You definitely can wrap a stone in nice wire & hang it as a pendant. One outfit I know of that educates people in the tricks of wire-wrapping is Preston Reuther.
Rings & Things sells a range of craft wire, and you can see it online at this page. We've also got books on wire wrapping...
