The Incomparable Diamond
Today's article looks at a rare and beautiful stone, The Incomparable Diamond. It was accidentally discovered in 1980 by a lucky girl living in the province of Mbuji Mayi in the Democratic Republic of Congo. After being sold to African diamond traders and buyers, the rock eventually came into the possession of the De Beers group. From there, it was sold to Donald Zale, the chairman of Zale Corporation, an American jewellery store chain. The stone made it's first public appearance in November 1984, on the 75th (diamond) anniversary of the Zale Corporation.
When discovered, the rough diamond had several irregularities, cracks and cavities. It was an incredibly large rock of irregular size, weighing around eight hundred and ninety carats, and took an incredible four years to shape! Cutting of the Incomparable Diamond was undertaken by an experienced diamond cutter, Mr. Samuels, who was renowned for his expertise. During the cutting process, several colour variations were found within the diamond, ranging from pale yellow to brown. The main body of the gem has a rich yellow colour.
