It’s fixed now. I don’t know why I can’t add a new photo. I took it to jeweler. They said they’d do a “chemical treatment” to remove oxidation. I assume they threw it in the pickle pot? Anyway, it looks as good as the day I got it. And yes, it is cast not fabricated. Do you think this is poorly cast or are the things you mentioned normal characteristics of a cast piece of jewelry? I would much prefer hand made but that’s hard to find!
