The "Golden Star" diamond being a fancy vivid yellow diamond is undoubtedly a Type Ib diamond, in which the intense yellow color is caused by single nitrogen atoms scattered in the crystal. The nitrogen atoms absorb visible light in the blue region of the spectrum, causing its complementary color yellow to manifest itself. However the occurrence of such intense yellow color diamonds is only 0.1 % of all naturally occurring diamonds. Other famous diamonds which belong to this category are the Alnatt diamond, the Mouna diamond, the Tiffany yellow diamond, the Sarah diamond and the Red Cross diamond.

Type Ia diamonds on the other hand have nitrogen atoms associated as groups of 2, 3, and 4 atoms, known respectively as A-aggregates, N3 centers, and B-aggregates respectively. A and B aggregates having even number of nitrogen atoms do not affect the color of diamonds. But, N3 centers having odd number of nitrogen atoms do affect the color of diamonds. Most of the natural diamonds are Type Ia and Sub-type IaAB, in which A and B aggregates and N3 centers occur together and constitute almost 98% of all naturally occurring diamonds. These diamonds range in color from light to medium yellow.


The Golden Star rough diamond weighed 204.03 carats and was discovered in the famous Finsch Mine located in the Northern Cape in South Africa. The date of discovery and other details of the early history of the diamond are not known. The diamond was purchased either by Graff diamonds, South Africa or its subsidiary South African Diamond Company (SAFDICO). The purchase price of the rough diamond is not known.

The rough diamond was partially processed in Johannesburg, South Africa, where Graff has its largest diamond processing factory employing over 300 craftsmen, processing diamonds weighing thousands of carats each year. But, the Johannesburg factory had been specially set up to process smaller diamonds. Graff's workshops that specialize in cutting larger diamonds are situated in Antwerp and New York. The Golden Star diamond after partial processing in Johannesburg was sent to the Graff workshop in New York, where it was cut and polished by the skilled master cutter in charge of the workshop, the late Antonio Nino Bianco, who transformed the rough stone into a magnificent cushion-cut, fancy vivid yellow brilliant of 101.28 carats. The loss of weight entailed in the process was 103 carats, equivalent to 50.5 %. Such loss of weights are normal in maximizing for quality and brilliance. Quality is usually achieved only at the expense of quantity. However, the master cutters were also able to create a satellite sister stone, also a cushion-cut fancy vivid yellow, weighing 16.63 carats.
