I purchased a bracelet, Sterling vermeil with (faux?) amethyst stones. I can’t make out the maker on the clasp. It is very tiny. It appears to be RR ST CO. Below that it says 1/20 – 12k and below that STERLING.
I can’t tell if it really is RR, maybe RB, BR? I tried taking a photo, but it is so tiny that it gets blurry when enlarged. I have looked at it through a loupe and still am unsure of the first 2 letters.
I will attach links to the photos, but I’m not sure they will be of help.
Thanks for trying!
