I’ve recently found this site and I’m awed by the knowledge and beautiful jewelry I’ve found here. I bought this squash blossom necklace in a thrift store several years ago. I’d wanted one for years. I’ve scoured the Internet looking for any squash blossom with stones like these, but never found one. The stones are lovely and remind me of jade, though I have never found reference to a jade squash blossom necklace so I don’t think they are jade. I’ve also been unable to identify the artist’s mark. Any information anyone can provide would be appreciated. (I won’t be upset if it isn’t authentic; it’s my favorite piece of jewelry and that won’t change.) I’ve never cleaned it. I was afraid of cleaning it wrong and damaging it. Any ideas about the best way to clean this also would be appreciated.
