Maybe obvious, but, find a silversmith and ask. Finding them is the hard part though, I think you're better off finding something broader, e.g. a jewelery shop that makes their own or does repairs, there may be relevant courses and education paths for it.

The trouble is, I think, that it's a dying art; for years a lot of these craftsmen have been superseded by cheap mass-produced fashion jewelry on the one hand, and cheaper or more practical every day use items. There's less pieces in people's homes that are worth handing down to younger generations.

But this can be reversed, it just means people need to make investments into items that may not be immediately useful or won't be used daily, things like grandfather clocks, jewelry, display pieces, art, etc.

One example I can think of is that my parents have an "analog" weather station on their wall, it's got things like a quicksilver thermometer / barometer, a weather glass, and a blurb of text, etc. They bought it because quicksilver was being banned for use in thermometers etc, so they figured it would be the last chance.

But the other factor, and we're zooming out a bit now, is that people have less permanence in their lives nowadays. Home ownership is decreasing fast, and people seem less interested in "being set for life", e.g. buying a house with the intent of living there forever and/or raising a family. But that's very tangential, lol.
