Lucapa Diamond Co. Ltd. has uncovered a diamond 172.67-carat Type IIa, D-color stone at its Lulo Project in Angola.
It is the fifth diamond weighing more than 100 carats discovered at the Angolan mine this year, and the sixth so far this year.
The latest discovery follows an announcement last week by the miner of the unearthing of a 104-carat Type IIa, D-color diamond.
