Richard Winterton Auctioneers has revealed jewellery including two natural diamond rings expected to exceed £6,000 is to be sold next month.
This includes a 3.78 carat single stone diamond ring, now estimated at £4,000 to £6,000, and a 1.46ct diamond solitaire, estimated at £2,000 to £3,000.
The larger stone is a certified 3.78ct round brilliant cut natural diamond of I1 clarity and M colour, set in an 18ct white gold ring.
The other lot is certified 1.46ct round brilliant cut natural diamond, of VS clarity and H-1 colour, set in a platinum ring.
Both stones have since been certified as ‘bright and lively’ natural diamonds by Birmingham Assay Office Gemmology Lab.
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.”
