Fancy yellow diamonds beat estimate price at Bonhams auction

11 december 2017
Two separate lots of fancy vivid yellow diamonds that belonged to the Cullinan family were sold at a Bonhams auction for well above their expected price.
A brooch set with three step-cut, fancy vivid yellow diamonds respectively weighing 5.29, 3.11 and 2.37 carats fetched $606,029 as compared to the pre-sale estimate of $268,000 to $402,000.
The second lot, a pair of round, fancy vivid yellow diamonds weighing 2.08 and 1.93 carats, respectively, sold for $167,319. Their initial estimate was $67,000 to $107,000.
The diamonds first surfaced in 1940, when R.V. Cullinan — son of the renowned diamond magnate Sir Thomas Cullinan — asked De Beers director Pierre De Villiers to buy him some diamonds on his next visit to Kimberley, Bonhams explained. On the train ride back from the mine, De Villiers showed what he had sourced to Sir Thomas Oppenheimer, the founder of Anglo American, who replied that he had something better. Oppenheimer revealed a set of yellow diamonds, which De Villiers purchased, keeping half and giving the others to Cullinan. The total price for the collection at Bonhams sale amounted to $773,350.
“The fancy vivid yellow diamonds in this collection are exceptionally well-matched in color and boast an enviable provenance,” said Jean Ghika, Bonhams' director of jewelry for the UK and Europe.
