A gem-quality diamond weighing 342.92 carats was found in South Africa at the famous Cullinan mine in the northeast of the country. The owner of the mine, Petra Diamonds, made the news on its website.
“The white stone is of exceptional quality and the highest purity,” the company said, publishing a photo of the diamond. The stone is expected to be sold at an auction in September.
The famous Cullinan diamond, weighing 3,106 carats and cut into a 530-carat Big Star of Africa diamond, was discovered at the Cullinan mine. The Second Star of Africa diamond, weighing 317 carats, was also recovered there.
These stones became the two largest stones in the crown of the British Empire.
In June, it became known that the elite diamonds went up in price amid limited supply and high demand for diamonds in the United States and China. At the last closed auction of the international corporation De Beers, the price of these precious stones was up 10% compared with the level of previous sales.
At the same time it was reported that De Beers raised prices for rough diamonds larger than 2 carats by about 10%. This year, the company has already sold more than $1.6 billion worth of rough diamonds, which was the highest since 2018.
