If all you do is size the ring down…just take the piece you cut
out…roll it paper thin…insert it into the seam and just weld
the ring…you will get a seamless sizing and a perfect color
match.Good luck Jurgen J. Maerz, PGI
Rose gold oxidizes rapidly- this may work, but use lots of flux.
The copper content also will probably make the alloy more
conductive to heat, so fusing may not work well.
