Vintage Marcasite and Nephrite Jade Ring Size 6 925 Sterling Silver. This measures 5 3/4, same size as my wedding band and this fits more loose on that finger likely because of the open dome shape on the inside allowing a little more finger room. Comparing with my other rings and fingers, I’d say it will fit up to at least 6.25. Or maybe a 6.5 if you don’t mind a little snug. Stamped sterling, but I can’t make out the other markings. Either Irish or Trish and something else is my best guess.
