Quick question: I have a platinum ring that was hand wrought using wire (no casting involved). Is it possible for such a ring to have porosity? I've had the ring for about 5 months and noticed today a lot of tiny little dings in one area on the shank. I have no idea what I did, but I wanted to make sure that these are just scratches and that there's no chance the little pits/dings are porosity. Assuming they're not, how easy is it to have dings polished out of platinum? Thanks in advance for any help!
