Exceptionally rare collection of Cullinan-owned Fancy Coloured Diamonds lead Bonhams Fine Jewellery sale this December in London

A collection of extremely rare Fancy Vivid Yellow diamonds with a provenance that is steeped in the history of world-class diamonds headline Bonhams London Fine Jewellery sale next month (7 December 2017).

Bonhams announced today that it will auction two important collections of Fancy Vivid Yellow diamonds, exceptionally well matched in colour and with an enviable provenance, hailing from the Cullinan family. This is the first time the coloured diamonds have come to auction.

The first important lot from the Cullinan collection is A Fancy Coloured Diamond and Diamond Brooch. This consists of three step-cut Fancy Vivid Yellow diamonds, weighing 5.29, 3.11 and 2.37 carats, estimated at £200,000-300,000.

The second lot is A pair of Fancy Coloured Diamond and Diamond Earclips. The brilliant-cut Fancy Vivid Yellow diamonds, weighing 2.08 and 1.93 carats, have a pre-sale estimate of £50,000-80,000.

The provenance of the gemstones is as magnificent as the diamonds themselves. Jean Ghika, Bonhams Director of Jewellery for UK & Europe, explains: "The diamonds were acquired in 1940 during a train journey when the present owner's father-in-law, R.V. Cullinan, son of the famous South African diamond magnate Sir Thomas Cullinan, asked his friend General Pierre De Villiers, a director of De Beers, to buy him some diamonds on his next visit to Kimberley. On the train back from the De Beers mine at Kimberley, Sir Ernest Oppenheimer asked General De Villiers "What have you got this time?" The General retrieved a packet from his pocket and proudly showed Sir Ernest, who replied "I can do better than that" and showed the General a set of yellow diamonds. A deal was struck. The diamonds were then purchased by the General, who kept half, and the other half were given to R.V. Cullinan. These are the diamonds which we will be offering for sale.

"It's important to remember that only one in approximately 10,000 of all diamonds mined has a fancy colour. Fancy Vivid Yellow diamonds are some of the rarest in the world and the best examples are prized for their extraordinary vibrant tone and sun-like hue. They are increasingly sought after and we anticipate that they will attract a lot of interest from discerning collectors around the world."

Bonhams will also be offering A Pair of Fancy Coloured Diamond, Diamond and Cultured Pearl Earrings, signed Cartier, for sale. The Fancy Intense Purplish Pink cushion-shaped diamonds, weighing 1.01 and 1.01 carats, each suspending a detachable drop-shaped cultured pearl and brilliant-cut diamond, are estimated at £100,000-120,000.

Moving on to colourless diamonds, Bonhams will also be auctioning A Diamond Single-Stone Ring, weighing 6.53 carats for sale. Estimated at £120,000-150,000, the old pear-shaped diamond is G colour, VVS2 clarity, and is an "extremely charming diamond" according to Jean Ghika of Bonhams.

For those who are searching for the statement bracelet to have this Christmas, A Diamond Panel Bracelet, estimated at £80,000-100,000, would be the perfect choice. Dated circa 1955, the wide articulated buckle-shaped strap with openwork detail, is set throughout with old brilliant, brilliant and baguette-cut diamonds in a repeating geometric design.

Jean Ghika, Bonhams Director of Jewellery for UK & Europe, adds: "December is the most wonderful time of the year to buy diamonds and we are delighted to have such an excellent choice of coloured and colourless diamonds on offer for our last sale of the year. Always classic, never out of fashion and extremely wearable, they make a perfect gift and an important addition to a jewellery collection."
