Diamond

A few days ago, 52-year-old Lucas Ncipe, assistant general manager of the Canadian diamond mining company Lucara, received a phone call from one of his engineers working at the Karowe mine in Botswana. “We found something incredible,” was the phrase he heard. He almost dropped the phone when he realized what it was about: the second-largest diamond in the world, weighing 2,492 carats.

This precious gem, found at the Karowe mine in northeastern Botswana, the largest diamond producer in Africa, is described by Lucara, the company that made the discovery, as “one of the largest rough diamonds ever found.”

A remarkable rough diamond weighing 2,492 carats has been discovered in Botswana, according to an announcement made by the Canadian mining company Lucara Diamond Corp on Thursday.

The gem was unearthed at the Karowe Diamond Mine, located in northeastern Botswana, approximately 430 kilometers (270 miles) from the capital city of Gaborone.
