FREETOWN, Feb 23: Sierra Leone said yesterday it had discovered a diamond worth $6.2 million, declaring it one of the most precious finds of the past decade.
The stone, dug up last week in the eastern district of Kono, was measured at 153 carats, making it significantly bigger than the largest find of 2013, a 125- carat diamond unearthed in the same area, the state-run National Minerals Agency said. "This 153.44-carat diamond is one of the finest diamonds to be found in Sierra Leone in the last 10 years," the agency said in a statement.
It was graded as D+ on the D-to-Z diamond colour scale, meaning that it has almost no yellow tint caused by nitrogen impurities, and the agency said it "could only be matched or surpassed by fancy diamonds such as blue or pink in terms of price". "The diamond is a cleavage in terms of shape and the clarity is of very high quality," the statement added.
"In other words, this is a premium stone as a result of its colour and clarity, and had it been an octahedron-shaped stone, it could have almost doubled the price of $6 million." - AFP
