Thank you for contacting Mearto with your appraisal inquiry.

It is a beautiful gold emerald and circonia ring. Such vintage jewellery are being offered at auction on a regular basis.
The design of the ring is very classic and modern at the same time. The colour of the emerald is good and clear. The ring does not appear to have many signs of wear and use which makes sense when it has only had one owner.

I believe that the emerald and gold would attract the attention of both collectors and dealers if it came up for auction.
The estimate provided is for a well-advertised specialised online jewellery auction, where I believe the emerald and gold ring has the best chance of realising its fullest potential. However, there is no measurement for the sentimental value you might attach to the lovely ring. Retail "asking prices" can be higher and vary.

Please let me know if you have any additional questions. I’m happy to help.
Thank you
