(CNBC) — A "spectacular" 404.2-carat diamond — which is almost three inches long — has been found in Angola. It is the 27th biggest ever discovered, according to the Australia-based Lucapa Diamond Company.
It has been analyzed as a rare Type IIa, a category that makes up less than 1 percent of the world's diamonds and means it is virtually flawless.
The diamond is the largest ever found in Angola, at almost twice the weight of the 217.4-carat "Angolan Star" recovered in 2007.
