Golden Jubilee

from Wikipedia, the free encyclopedia

The Golden Jubilee is the largest cut diamond in the world.

In 1985 a brown rough diamond weighing 755.50 carats (151.1 g) was found in the Premier Mine in Cullinan (South Africa) , which was initially called the Nameless Brown .

The work of the stone was entrusted to the well-known diamond cutter Gabi Tolkowsky . He worked the diamond with tools specially manufactured by him and his team. The result of the one year processing time was a diamond cut with 148 perfectly symmetrical facets. The weight, which is normally reduced by up to 50% during processing, could be kept at a remarkable 72% of the raw weight, so only 28% was lost during grinding.

Weighing in at 545.67 carats (109.134 g), the Golden Jubilee Diamond has been the largest cut diamond in the world ever since. He replaces the Star of Africa , who had held this record since 1908. The record for the largest rough diamond of 3,106.7 carats is still held by the Cullinan , which was found in the same mine and from which, in addition to the Star of Africa , several important cut diamonds were made.

In 1995, a Thai group of companies bought the diamond from De Beers and brought it to the Vatican , where it received the blessing from Pope John Paul II . In 1997, the diamond was presented as a gift to King Bhumibol Adulyadej in honor of the 50th anniversary (the golden jubilee ) of his accession to the throne. The previously nameless diamond became known as the Golden Jubilee Diamond. This diamond should be set in the Thai royal scepter. Today it is located in the Royal Palace and is part of the Crown Jewels.
