So if no Karat marked then what could it be? by: Anonymous
No diamond but a black stone, maybe an onyx on the front . I can’t find any 10k , only see the numbers number 25. ?

Please help test for silver by: Anonymous
I have an earring that is silver in color with an onyx stone on front. The back has only the numbers 25, what does this mean?? There's no 9 or any other symbols so I'm baffled...

You said it has a Diamond? by: Margie
What carat weight is the diamond in the ring? Would it be a quarter carat, perhaps?

Other elements that make up ring by: Joyce
Hi Rebecca "Nothing less than 10-karat gold can be legally marked or sold as gold jewelry in the United States."
I believe the .25 indicates what percent the other element or elements are that make up the ring's metal.
