I've been given an old ring from my Mum who wants it valued and repaired if at all possible.

I thought this would be an easy thing to achieve in Zurich but apparently not. 2 Jewellers on bahnhof str. told me the ring was foreign so they wouldn't value it and that it was too delicate for them to risk repairing it, and suggested I just use soapy water to clean it.

Anyone know where I can take a foreign, 60+ year old ring to be valued and hopefully get the diamonds reseated (or whatever they do) in Zurich.

Try an antique jewelery dealer for the valuation.

Avoid soapy water to clean it. When I had my ring made, the jeweller told me to use liquid window cleaner, brings it up a treat

There is a place off Münzplatz that will do it, I can't remember their name.
