FREE: 5 men's rings size 6 to 8

The listing, 5 men's rings size 6 to 8 has ended.

They all look to be in good condition..But one has one of the stones missing and another has wear marks really bad as seen on the photo..All I know is one is a size 7 the rest I don't know..Any other questions feel free to ask..Thanks for looking..:) Also one has writing on the inside but I don't know what it says, it's the one with the wear marks..Another says 7, I'm thinking the size maybe ??? None of these rings or silver or gold..I don't know what the metal is either..sorry..
