Natalie Brandon, jewellery valuer, said: “It immediately became clear to me that we had a real treasure trove being presented. As soon as I saw these wonderful stones my eyes widened. The whole collection is lovely and these two diamond single stone rings are absolute showstoppers. It was a pleasure to be able to tell our client the good news.”
Lisa Spence, Richard Winterton Auctioneers’ head of jewellery, added: “When we are presented with stones of a certain calibre, as part of our processes we submit them to Birmingham Assay Office for analysis and certification. These have come back with reports certifying the status of natural diamonds, which will help with the sale. The fact that one of these is an almost 4 carat natural diamond is especially impressive.”
