A team of miners working for an Australian company has dug up what could be the largest piece of diamond ever to be found in Angola. The massive 404-carat gemstone is believed to be worth about $14 million. ...The company said that the diamond measures at about seven centimeters (2.75 inches).

...The discovery of the 404-carat diamond comes months later after another firm, Lucara Diamond, unearthed a massive 1,111-carat diamond of its own in Botswana. The Lucara find is considered to be the second largest diamond in the world, following only the 3,106-carat Cullinan diamond discovered in a mine in South Africa back in 1905.
