Inside the great Graff diamond hack

Billionaires with a wedding anniversary coming up or an affair to apologise for could be forgiven for thinking that some expensive jewellery from Graff would do the trick. Perhaps monsieur would be interested in a Classic Butterfly Chandelier diamond necklace for £210,000? Or maybe he would prefer to buy madame a pair of Tilda’s Bow pear-shape diamond stud earrings for £265,000? Surely nothing says “I love you” or “Why won’t you take me back, I miss the kids” than Graff’s diamond-encrusted watch inspired by Cy Twombly – a timepiece riffing on the American artist’s swirly paintings – that sells for £365,000?
