Closeout all I have left, You are buying 10pcs. These have quite a lot of antiquing on them. If you are gluing them on something and mounting a stone in there not going to be an issue. Probably even clean up if you felt like polishing them. This is a very large and bold round setting. This is cast, as opposed to stamped, so it is HEAVY. The finish is antique silver. There is no pin on the back. Glue or solder one on if you need to. Big open filigree allows for plenty attachment points for hanging. This would also be good as a centerpiece on music boxes or other types of decorative applications. The cameo shown here is just an example so you can see what it looks like, your buying just the setting, holds a 40x30mm cameo
