(CNN) - Miners in Africa have unearthed one of the largest diamonds ever found.
The glittering stone weighs 910 carats, making it the fifth-largest gem-quality diamond ever found.
It's likely worth tens of millions of dollars.
The diamond was found inside a mine in the tiny African nation of Lesotho. The mine in question is known for producing large, high-quality diamonds.
London-based Gem Diamonds owns a majority stake in the mine. The company says the diamond is of extremely high quality.
