Thank you for contacting Mearto with your appraisal inquiry.

It is a lovely vintage diamond cluster ring. The value of the ring would largely lie in the size, colour and clarity of the centre stone. If the centre stone is over 1.00ct, I would suggest the minimum estimate be around £800 - £1000.

I believe this ring could achieve within the estimate if the centre stone is less than 1.00ct, however, there is no measurement for the sentimental value you might attach to the ring.

Do let me know if you have any additional questions. Many thanks!
