March 21, 2025‘Extremely rare’ pink diamond necklace sells for £190k at auction
An ‘extremely rare’ pink diamond necklace has sold for £190,000 at auction. The necklace, signed and numbered by Cartier, was sold at Tennants Auctioneers in North Yorkshire on March 15.
The 8.62 carat diamond, which is presented as a necklace with a simple white claw setting, was found to have some colouration by Tennants’ jewellery specialist, Jessica Fall. Following consultation with the Gemmological Institution of America (GIA), the gem was officially graded as very light pink with a clarity grading of VVS1, defined as ‘just below flawless: of high clarity’.
Ms Fall said: “Pink diamonds are officially defined as ‘exceptionally rare’; some estimates suggest as few as one in 10,000 gem-quality diamonds mined worldwide show any discernible colour.
