BOTSWANA, SOUTH AFRICA (CNN/WIS) - The world's second-largest diamond has been discovered in South Africa.
It is more than 1,100 carats and was found in a Botswana mine owned by the Lucara Diamond Company.
Shares of the company stock rose 35 percent after it unveiled the stone on Wednesday.
The Type IIa stone measures 65mm (2.56 inches) x 56mm (2.2 inches) x 40mm (1.57 inches) in size and is the largest ever to be recovered in Botswana.
Determining a price for the gem will depend on several factors.
The company says it also uncovered two white diamonds in the same mine, one was 374 and the other was 813 carats.
The largest diamond ever found was the 3,106 carat Cullinan diamond, discovered in South Africa in 1905.
