It's a very old ring ( I have the rest of the set... Earrings and brooch) my grandpa gave my Granma. This one is a pretty big piece. A big emerald sorrounded by lots of diamonds, set on platinum. I have a picture
My grandpa gave it to my Granma back in the 50s. She gave it to my mother and now she wants to sell it
Thank you for contacting Mearto with your appraisal inquiry.
This is a wonderful example of mid-century jewellery design. I love the way the step-cut emerald is framed by and amazing multi-cut diamond spray - mid 20th century perfection! Mid 20th century jewellery is very popular at auction at present, particularly platinum pieces. From the images provided, this ring appears to be in good condition and there is no serious damage visible in the images provided.
The diamonds look bright, lively and very well matched which is wonderful. The emerald looks to be of good saturation with typical inclusions. All emeralds are oil treated, which is accepted as standard practice in the industry, however, without inspecting it or sending it to a lab we are unable to tell to what level this emerald has been treated. Also, a huge factor with emerald value is its geological origin, the most desirable being Colombia. Unfortunately this isn't something I am able to tell you from some images, however, upon closer inspection an auction house is likely to be able to tell whether it's worth sending to a lab for identification purposes.
A fair market estimation for an mid 20th century emerald, diamond and platinum engagement ring (assuming oil treatment and non-Colombian) would be between 2000 - 4000 GBP. This estimate is based on actual recent past recorded auction sales of comparable items. Retail asking prices can be higher and may vary. It's worth noting, insurance valuations are often higher as pieces are insured for new replacement rather than second hand replacement.
I believe this beautiful piece would easily achieve within the estimate provided, however, there is no measurement for the sentimental value you might attach to the ring. I would suggest taking it to an auction house to be fully inspected for a more accurate valuation.
Do let me know if you have any additional questions. Many thanks!
