Thank you for contacting Mearto with your appraisal inquiry.

It is a beautiful ring. Such vintage jewellery are being offered at auction on a regular basis.
The design of the ring is very smart and fashionable. The quality and colour of the diamonds appear to be good. The ring does not appear to have major signs of wear or use.
Unfortunately the secondhand price does not resemble any retail price or the price and costs you pay when you have a brand new piece designed and made.
However it is a nice ring and I believe it will attract the attention of both collectors and dealers if it came up for auciton.

The estimate provided is for a well-advertised specialised online jewellery auction, where I believe the ring has the best chance of realising its fullest potential. However, there is no measurement for the sentimental value you might attach to the beautiful 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
