if your pearls are still in good condition and they have been looked after (and rethreaded) they will naturally be worth more, than in 1958. If they have not been looked after or stored well and away from other pieces of jewelry, they might not be worth as much as in 1958. If you can get photos of the pearls you can get a jewelry valuation online. It is an easy process and the certificate is downloaded to your computer.
