I've never heard of sizing beads, what a clever idea!I didn't see any 6 prong options with a bridge in their selection. I looked twice to make sure. That 2nd one looks just like the Cartier 1895.
The only modification they would do to mine was the band width. The shank is 2.2 on mine. They put my sizing beads in as well.
How does this compare with having the circumference of the shank reduced? I've recently lost a fair bit of weight and some of my antique opal rings are too big now but I'm very wary of having anything done to them.
If this has already been discussed in a separate thread, I apologise, would someone kindly link me to it.
