Hi All, first time poster here. I just purchased this navette style ring from Ruby Lane and I was wondering if anyone could give me a date range for when it was made. From what I've seen this style was popular from the 1860's all the way through the 1920's. The listing simply said Victorian and I was wondering if anyone here could give a more precise range. The diamonds are Old Mine cut and it tested as 14 kt gold, but is unmarked. I've never seen this type of scalloped edge before, so I'm super curious about it. Thanks in advance!
