The listing, Silver and turquoise chip zig-zag ring, vintage: size 6 / 6.5 has ended.
I believe this is sterling silver, but it has no easily visible markings. There is a spot on the inside of the band that i suspect was a stamp of 925, but has worn almost completely away. I have had this ring since i was 14, and it was in the possession of a friend for years before that, so it's definitely over 20 years old, not sure about how much though. the inlay seems like glass with turquoise chips embedded in it. Again not entirely sure. The ring is size 6/6.5, according to my finger. which it's a tiny but too small (for i'm a 6.5. I can get it on with a bit of effort.)
