925 SU mark
925 SU mark
I have seen a 925 SU mark on several pieces of jewelry-all from different countries (Italy, Mexico, Thailand...). I have some earrings with this mark, but they are so light weight that I doubt they're sterling. Could the SU be indicative of some type of silverplate?

Thanks, Tom. Hmmm...In my searching I ran across quite a few eBay auctions that listed jewely w/ this same mark as vintage, but of course they may have been incorrect in their assessment. Because of this I thought the mark might be from a company that had been around for awhile. I don't believe my earrings are vintage though, and did not list them as such. Appreciate your response! ~Sherry

Re: 925 SU mark
Although I have seen some pieces from other countries stamped with SU, an "SU" stamped on a sterling silver piece of jewelry usually means it is from Italy. "SU" can be by itself, within a circle or with 925. (for 925 parts 1000 silver, ie sterling)

Hi Sherry, I have purchased a ton of sterling pieces some that are vintage, & some that are not. I have seen a variety of the marks as well Ie: with a circle around the SU alongside 925/S925/925S, or without the circle. I have been in the precious metal & gemstone industry and have amassed over 25 yrs experience. I believe what you most likely have is a piece purchased off of a website/infomercial or the actual channel QVC. SU is considered a precious sterling silver metal. It is generated by SU & in fact comes from Italy. So they do have notariaty & do manufacturer pieces today. Meaning that bc you feel you're piece isn't vintage (probably bc it's not) but there are a ton of pieces out there produced by the same company that are.
