Hi All,
I just purchased a ring that has the 925 marking which I know what that means but it also has the marking of SU in a circle. Does anyone know what the "SU in a circle means"? I've did some searches and I'm not coming up with anything.

I can only offer a possible lead. The was a Mexican manufacturer who used a SU in a circle mark.
The pieces I have seen also had a Mexican registration mark that has been used since about 1980.
Sorry, don't know the name of the manufacturer.

Thanks Pat, I did quite a bit of surfing the net and couldn't find anything either. I also thought it may have come from mexico. I love the ring it looks like one of those diamond rings with a cluster of real tiny diamonds, but not diamonds the stones are black and they sparkle like diamonds. From a distance they do look like diamonds. I'll keep searching. Thanks again.
