Thank you for viewing. This is a vintage sterling silver ring. ※ The difference from SV925 is the type of alloy mixed with the silver. Both use 92.5% silver, but while sterling silver uses pure copper as the other metal, SV925 may contain various metals such as nickel and aluminum. Sterling silver, which only mixes copper during creation, is easier to restore its shine with care even if it discolors. The size is equivalent to size 19.
