When we size a ring down, a small piece of the bottom of the “shank” is cut out and then the remaining sides are either soldered or laser welded back together.
If the ring is being sized larger, a matching piece of silver, gold, or platinum is added into the shank and then soldered or welded back together.
If the ring has other gemstones, they will need to be checked and tightened as they can shift and loosen during the sizing process.
The sized area is polished and refinished to make the seam virtually invisible. Then the entire piece is polished and refinished to make the ring look like brand new, and if necessary, rhodium plate to restore the bright white finish of white gold.
