The Pumpkin Diamond was bought for $1.3 million at a Sotheby’s auction on 30 October 1998, one day before Halloween, and was named by its purchaser, Ronald Winston, perhaps as it resembled a real cut pumpkin in its colour. Orange diamonds are amongst the rarest colours found in diamonds, with a price to match. Secondary hues found in natural Fancy Orange diamonds are red, pink, purple and yellow.
The Pumpkin Diamond is a 5.54 carat, Fancy Vivid Orange, cushion-shaped stone. The original rough 11.00 carat, brownish orange rough stone was discovered in the Central African Republic in 1997. Its actual origin is unknown, but as it was owned by a farmer, it is assumed to have been found in an alluvial deposit.
William Goldberg of the Goldberg Diamond Corporation cut and polished this diamond, and it was while polishing it that its vivid orange colour was revealed, making it one of the largest fancy vivid orange, naturally coloured diamonds in the world. The combination of the rare colour and its colour rating make it one of the rarest diamonds ever found. Ronald Winston and Phillip Bloch designed the ring, the Pumpkin Diamond being set between two smaller white diamonds. It was worn by Halle Berry to the 74th Academy Awards in 2002.
The Pumpkin Diamond was displayed as part of the Smithsonian’s Splendor of Diamonds exhibition in Washington D.C. in 2003, having been selected as the only known diamond of its colour and size in existence.
To quote the Smithsonian: “What makes this orange diamond so special is that the majority of orange diamonds manifest with a brown undertone. The Pumpkin Diamond does no such thing. It is pure, vivid orange, catapulting it into diamond history as one of the largest fancy vivid natural orange diamonds in the world”.
It is rumoured to have been sold in March 2005 to an anonymous buyer for just over
