I found this ring in my bag of assorted rings. There are no markings anywhere. I have no idea what type of metal it is made from & it is not attracted to a magnet. It weighs 0.5 oz. or 14 grams & is a size 10 1/4. I tried doing a Google image search and came up with nothing similar. Googling "DATAS II U" also got me nowhere. So any ideas??? Thanks for any & all advice or opinions!!!
I was thinking along those lines - possibly something to do with Star Trek/Star Wars/Marvel Comics etc.
It definitely isn’t Trek and I don’t recognise it as any of the other SF universes I’m familiar with.
