The name "Pumpkin" is a rather unusual name for a diamond, but this was the name selected for the diamond by it's purchaser Ronald Winston, of the House of Harry Winston, who bought the stone at a Sotheby's auction, just one day before the Halloween Day in 1997. A hollowed out pumpkin, carved with a demonic face, and lit with a candle inside, known as a "jack-o-lantern" is a popular symbol of the Halloween Day, which falls on the 31st of October each year. Another possible reason for the selection of the name "Pumpkin", would have been the fancy vivid orange color of the diamond which almost resembles the color of a cut pumpkin.
5.54-carat, fancy vivid orange, cushion-cut Pumpkin diamond
The diamond is a 5.54-carat, fancy vivid orange, cushion-cut stone. In spite of it's smaller size, the extreme rarity of the orange color in diamonds, makes the "Pumpkin" a notable and famous diamond. In fact the G. I. A. had reported that the "Pumpkin" diamond was one of the largest fancy vivid orange colored diamonds rated by them. Fancy vivid is a high color rating for any colored diamond, and stones of this color grade are rare and unique. The combined rare color grade, in an extremely rare color, orange, makes the "Pumpkin" one of the "rarest of the rare" of colored diamonds.

Color in diamonds is caused by impurities, structural abnormalities, or natural irradiation. The commonest impurity found in diamonds is Nitrogen. Almost 98 % of all natural diamonds contain Nitrogen as impurity, and this property is made a basis for the classification of diamonds. Diamonds that contain detectable quantities of Nitrogen are called type I diamonds and those that do not contain detectable quantities of Nitrogen are called type II diamonds. 98% of all natural diamonds are type I and the remaining 2% are type II.
Type I diamonds are again sub-divided into two depending on whether the Nitrogen atoms are found in groups or scattered as single atoms.
Type Ia - Nitrogen atoms are found in groups or aggregates of two or more atoms. Almost 98% of type I diamonds belong to this sub-group.
Type Ib - Nitrogen atoms are scattered as single atoms. Only 0.1% of type I diamonds belong to this sub-group. Orange diamonds also belong to this sub-group. The Nitrogen atoms absorb visible light in the blue end of the spectrum producing the intense yellow color known as canary yellow, orange or sometimes amber colors. As only 0.1 % of all naturally occurring diamonds belong to this group, the canary yellow, orange and amber colors are extremely rare in diamonds.
Thus orange diamonds are rare type Ib diamonds.
The diamond was mined in South Africa in 1997, but the mine of origin is unknown. It might have sometimes originated in the alluvial deposits of Southern Africa, because the original owner of the stone is believed to be an unnamed farmer. However, in the past the Zwartruggen dikes of South Africa, had been identified as a relatively prolific source of amber and orange colored diamonds, with 2-5 % of the output from these mines being amber or orange colored. A small number of amber and orange diamonds were also found in the output from the Finsch and Premier mines.
The rough Pumpkin diamond when it arrived at the William Goldberg Corporation was a brownish-orange, 11-carat rough diamond.
The rough stone was cut and polished by diamantaire William Goldberg himself of the Goldberg Diamond Corporation. Orange diamonds are often modified by a brown color and the rough pumpkin diamond was no exception. However, surprisingly as the cutting proceeded a unique pure orange color was revealed, which assumed an intense orange color when the cutting was completed.
The cut and polished orange diamond was put up for auction at Sotheby's New York, on October 30, 1997 and was purchased by Ronald Winston of the House of Harry Winston for a price of US$ 1.3 million. The unnamed orange diamond was then christened the "Pumpkin Diamond" by Ronald Winston.
Ronald Winston later set the diamond in a ring between two smaller white diamonds. Halle Berry is reported to have worn the ring to the 2002 Oscars, where she won the Academy Award for the best actress for her role in the film Monster's Ball.
The "Pumpkin" diamond was displayed as part of the Smithsonian's "Splendor of Diamonds" Exhibition, held between June 27th and September 30th, 2003, which also featured other famous diamonds, such as the Millennium Star (colorless), the Alnatt diamond (yellow), the Heart of Eternity (blue), Steinmetz Pink (pink), the Ocean Dream (blue-green)and the Mousaieff Red (red)diamonds. Diamonds of all colors were represented in the Splendor of Diamonds exhibition, except for green, purple and brown/cognac colored diamonds. The "Pumpkin" diamond was given the rare honor of being selected for this exhibition, because it was perhaps the only known diamond of its color and size in existence, like the blue-green Ocean Dream diamond.

Starting from the pear-shaped Millennium Star in the center, the diamonds in the photograph above in the clockwise direction are - the Allnatt diamond, the Ocean Dream diamond, the Mousaieff Red diamond, the Pumpkin diamond, the Heart of Eternity diamond and the Steinmetz Pink diamond.
The diamond's estimated value in the year 2005 was around US$ 3 million, and was rumored to have been sold to an anonymous buyer in March 2005.
