I have a women’s size 7 cz silver ring. It’s beautiful and fits good. I bought it as sterling and I’ve had no problems out of it but it’s not stamped that I can find. I usually react to things that aren’t sterling but no problems but the stone itself is too big for me. I’m in the Cookeville area and can meet in the Cookeville area. Please text any questions to 931- nine 7 9- forty 1 zero 6. Thank you
