Lot 2084* - A163 Jewellery (Part 1) - Tuesday, 04. December 2012, 02.00 PM
Unmounted brilliant-cut diamond of 6.03 ct, D/IF, Type IIA. With GIA Report No. 1146762802, with an additional letter of certification from the Gemmological Institute of America for its identification as a Type IIA. Type IIA corresponds to the chemically purest group of diamonds and has an exceptional optical transparency. Less than 2% of all gemstone diamonds belong to Type IIA. The Type IIA group was initially determined for diamonds of Indian origin (especially from the Golconda region), but, ever since, such diamonds have been found in all the diamond mines of the world. Examples of famous diamonds are the Cullinan I weighing 530.20 ct and the Koh-i-Noor weighing 105.60 ct. This brilliant-cut diamond was cut from a rough diamond of 15.93 ct. The stone was found in the Letseng diamond mine, in the Maloti Mountains of Lesotho.
Over a course of 3 months, the world-wide operating Brachfeld Group cut the diamond, using state-of-the-art technology and equipment, in order to obtain the highest cutting standard: excellent cut, polish and symmetry.
