A 7.5 carat fancy purple pink was also recovered from the mine.
The Lulo partners were expected to include the 128 carat diamond and 7.5 carat fancy purple pink in the next international tender, along with the 75 carat Type IIa top-colour diamond recovered towards the end of 2018.
Lulo recently had a historic tender of seven large, top-quality diamonds, in Angola, which raked in $22.9 million at an average price of $33,530 per carat.
