The Pumpkin Diamond

By 06.09 September 20th, 2018 No Comments

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
$3 million.

Cut

Nothing is more impactful on a precious stone’s brilliance than its cut. The cut refers to the angles and proportions of a diamond. Known in the industry as ‘fire’, referring to the coloured light reflected, and ‘brilliance’ for the uncoloured light. The cut of a diamond – its form and finish, its depth and width, the uniformity of the facets – determines its beauty. The skill with which a diamond is cut determines how well it reflects and refracts light. A diamond should be cut proportionally, neither very shallow not very deep, given its dimensions. A diamond’s cut is its most important characteristics and a measure of its apparent beauty.

Certificate

A diamond certificate or grading report provides an expert opinion on the quality of the diamond and is provided by an independent gemology lab. Trained gemologists with specialized equipment measure the weight and dimensions of the diamond and assess quality characteristics such as cut, color, and clarity. Brilliant Earth diamonds are certified by the world’s leading gem grading labs including GIA, IGI, and GCAL.

Depth

The height of a diamond, from the culet to the table referred as a Depth of the diamond . Depth % is the height of the diamond as a percentage of the girdle diameter.

Table

Table referred as the largest facet of a gemstone, located at the top. Table % is the table width as a percentage of the girdle diameter.

Polish

Polish refers to the smoothness of the exterior of a diamond. Polish is graded from Ideal, Excellent, Very Good, Good, Fair, or Poor. Polish grades of Good or higher have the least effect on the brilliance of the diamond and recommended by us for the finest quality jewelry.

×
Symmetry

Symmetry refers to the angles to which the facets are aligned. Basically exactness of the shape of a diamond, and the symmetrical arrangement and even placement of the facets. If facets are misaligned, the diamond may poorly reflect light. Symmetry is graded from Excellent, Very Good, Good, Fair, or Poor. We recommends diamonds with Good or higher symmetry grades.

Fluorescence

Describes the diamond’s response to ultraviolet light. In diamonds with strong or very strong fluorescence, there may be some interference with the flow of light which causes a milky or oily appearance. Canadian diamonds almost always have none to slight fluorescence.

Measurements

Diamonds with “fancy” shapes are measured according to their length, width and depth. These diamonds will have a longer axis (the biggest measurement) and a shorter one that represents their width. The depth indicates the measurement of the diamond from the bottom to the top. The relative proportions of a diamond ultimately affect its quality and value.

Round-shaped diamonds are never perfectly round even though they may seem to be that way when you look at them. There is a tiny variation between maximum and minimum diameter, so dimensions are reflected as measurements of maximum diameter, minimum diameter and depth.
