The Letlapa Tala Collection
Five blue diamonds of exceptional colour, clarity and size from the legendary Cullinan mine in Africa will be offered by Petra Diamonds Ltd at a special tender in November.
The Letlapa Tala Collection consists of five Type IIB blue diamonds of 25.75, 21.25, 17.57, 11.42 and 9.61 carats in size. Type II diamonds contain no detectable nitrogen in their chemical structure and tend to display exceptional transparency. Type IIB stones contain a small amount of boron, which is what determines their blue colour.
Letlapa Tala means “blue rock” in Northern Sotho (commonly known as Pedi), the predominant language spoken in the Cullinan area.
“Blue diamonds are so rare that most people working in the diamond industry have never even seen one. There are no official statistics on their recovery, so it is therefore even more unusual that these five spectacular stones were all recovered within the space of one week’s production in September 2020,” revealed Petra Diamonds.
The Cullinan mine is known as the world’s most important source of blue diamonds, as well as being the source of many other historic and magnificent stones, including the 3,106-carat Cullinan diamond, which was cut to form the 530-carat Great Star of Africa and the 317-carat Second Star of Africa – the two largest diamonds in the British Crown Jewels.
“This is likely to be the first time that five blue rough diamonds have ever been offered for sale at one time, with buyers being offered the chance to bid either on individual stones, more than one, or for the entire collection,” noted the diamond miner.
The Letlapa Tala Collection will be available for viewings in Antwerp from October 25 to November 1; Hong Kong from November 5 to 10; and New York from November 16 to 20.
The tender will take place shortly thereafter and will close at 3pm GMT on November 24.
