NO, i clearly HAD a ring marked 923! i thought it was marked 925 b/c i didn't look at it close enough until i put it in silver cleaner and half the top layer dissapeared. i'm on here looking to see what 923 means. can't find it, but from the looks of my ring it means SilverPlated. or polished or something strange. so warning anyone who has 923 DO NOT soak in jewelry cleaner.
. If the piece shows a stamp of .923, it is just shy of the Sterling silver designation.
Inquire with the jeweler about the metals in the jewelry. Gold and silver are particularly soft metals, and so they are typically mixed with others in order to hold their form. Copper is the most common mix with silver because it helps retard the tarnishing process that silver is so prone to. If a 923 is stamped on a piece of silver jewelry, this means that it is 92.3 percent silver, and then 7.7 percent copper or other metals.
I found the above on a couple of websites.
That was me who posted the website. When I clicked on the link, I got page not found, and had to get in a different way. So they may have changed their website later on, but when I originally posted it did say their silver was 92.3%. And I also found reference to the composition of 92.3% silver, as stated above.
But to the poster above you -- as someone stated are you sure the "3" is not really a "5"? 92.3% is not common, so you do need to make sure who you purchase from as there is a lot of fake hallmark stamps out there.
