Biggest diamond in 100 years fetches 53 million dollar

The 1,109-carat stone, which is said to be 2.5 to 3 billion years old, was bought by British diamond dealer Graff Diamonds for $47,777 per carat on Monday. Lucara recovered the huge diamond from Botswana’s Karowe mine nearly two years ago. 

The seller named it “Lesedi La Rona”, which means “Our Light” in Botswana’s Tswana language. It had originally hoped to get at least $70 million for the stone, describing it as the biggest gem quality diamond found in more than a century, CBC News reported.
