I'm wanting to upgrade the quality of the diamonds in my 3mm basket setting eternity (platinum). Can this be done with same sized stones, or will the jeweler have to rebuild the entire ring? Thanks!
This depends on the condition of the original setting, the opinion and rate of pay of the setter who might do the work, and how refined you expect the second effort to appear.
