The type IIa rough, named the Lulo Rose, is “believed to be the largest pink diamond recovered in the last 300 years,” Lucapa said Wednesday. It is also the fifth-largest diamond from Lulo, and the deposit’s 27th over 100 carats since commercial production began in 2015. Lucapa plans to sell the diamond through an international tender conducted by Angolan state diamond-marketing company Sodiam, it noted.

“The record-breaking Lulo diamond field has again delivered a precious and large gemstone, this time an extremely rare and beautiful pink diamond,” said José Manuel Ganga Júnior, chairman of the board of state-owned Endiama, one of Lucapa’s partners in the deposit. “It is a significant day for the Angolan diamond industry.”
