A customer ordered a comfort fit 22k 6mm gold ring, 2mm thick, flush set with VS G diamonds scattered around the band. The first pilot hole was for a tiny 1.5mm, and of course, resulted in not only the drill bit breaking halfway through the hole at a wonky angle, but after going in next to it with a .4 ball bur to help it out, resulted in the ball head snapping off of that and lodging next to the broken drill. Oh joy!
I went to the backyard so the steam could release from my brain before my head exploded and did my best to zen out as much as possible.
After wasting a heck of a lot of time, I finally got both pieces out and set a larger stone in that spot. Second stone went in well. For the 1.7mm third stone, the drill bit breaks halfway through AGAINNNNN. Luckily no one was around to hear what came out of my mouth!
After initially rounding out this ring, I didn’t anneal it. My thought was that 22k is soft enough. I have about 14 more diamonds to set in this ring, and I’m tempted to anneal with the three stones in place, staying off the stones with the flame, and air cool.
With this quality of stones, I’m hesitant and I’d love some advice before going ahead. I’m also hesitant as I don’t want the customer to end up with a ring where the gold is as soft as butter.
Maybe I should just go bigger with the pilot drill, as the broken ones were .7mm… Diamonds will range from 1.25mm ~ 2.5mm.
