If you deal with old jewelry, you know all too well about prying small stones from jewelry. When getting a batch of old gold or platinum ready for refining it is best to remove the old stones.
We recently sent a batch of old rings to a refiner who does a chemical melt, the metal is put into a beaker and is broken down. The stones fall to the bottom of the beaker, without damage.
We tried it with a service located outside the USA, but we have found one such company located in St. Paul, MN.
No actual experience with this company, but certainly take a look at Stebgo Metals if the idea of no longer doing removal of stones by hand is appealing to you.
