Hello to All
I need to size down a man’s wedding band that is 18KY with a 950 Pt sleeve running down the center. See pics. The Pt is set into the 18K in a channel and does not show from the inside of band.
It need to be sized down a couple of sizes so compressing won’t work. In the past I have attempted to size this type of ring using gold solder but have had problems as the 2 metals do not expand the same with heat make a gap. I do not have a laser but do have a PUK. Any suggestions would be most welcome.
