I inheritied a few different turquoise/malachite rings from a relative; I was able to identify the bell trading post rings using the website, but not this one. I can't really make out anything in the hallmark besides the 925 and the ring size. I'm assuming the little round symbol next to the mystery hallmark is just a copyright symbol.
please let me know if I need to provide any other pictures! I'd love to know what this is. thank you!
