I wonder because I think it has unusual characteristics. It is set in white gold and dates back to the deco era. Wheat pattern and ornate side profile. Thin setting that makes stones look bigger.
The stone itself is what I find interesting. It is J VVS2 with a very good cut and also a GIA report. It is 0.71 carats, and is an old mining section. It has many colors and lots of sparkle. What I find unusual about this ring is the very good cut combined with being an antique diamond. I keep it, of course, but what do you think such a thing would sell for?
