The ‘Pink Promise’, says Rahul Kadakia, International Head of Jewellery at Christie’s, is ‘the Picasso of the pink diamond world. When you look at the shape of the stone,’ he adds, ‘it’s so elegant. It’s a cross between an oval and a marquise — what we call a “moval”. It’s a fabulous diamond.’

Leading the 28 November Magnificent Jewels  sale in Hong Kong, this oval-shaped fancy vivid pink Type IIa diamond, weighing approximately 14.93 carats, is set within a circular-cut diamond surround, gallery and hoop. The stone is enhanced by circular-cut pink diamonds and mounted in platinum.

‘A pink diamond is rare to start with,’ says Lisa Hubbard, Senior Adviser to Christie’s International Jewellery. ‘But an oval pink diamond of this weight is very rare, very hard to find. It is a singular diamond in many ways, and just beautiful.’
