This is a silver ring with three skulls. It is not made of silver 925. It does not stick to a magnet. Weight is 19.47g. I think I received it a long time ago because someone didn't need it, but I don't remember. I'm decluttering because I'm moving. It's probably size 17. I don't have any measuring tools, but my thumb is 5.7cm and it fits perfectly. I'm just estimating, so I can't say for sure. It's worn overall. The head of one of the skulls is chipped and black is showing. Please purchase only if you understand the condition. I will wrap it lightly in bubble wrap for shipping.
