A giant diamond which weighs over 100 grams has been found at a South African mine.
The gem - worth in excess of £12m (about $19.1M US) - was found in at the famous Cullinan mine and is currently being examined by experts who will calculate its exact value.
It was recovered along with a 168 carat one and two smaller 58 carat and 53 carat ones.
Petra Diamonds, who run the mine, say the diamond has exceptional colour and clarity, and is one of the 20 biggest ever discovered.
As with all giant diamonds, the 507 carat gem will be given a name...

Johan Dippenaar of Petra said: "The Cullinan mine has again given the world a spectacularly beautiful and important diamond.
"Initial indications are that it is of exceptional colour and clarity, which suggest extraordinary potential for its polished yield. We now eagerly await the findings of the expert analysis."
The largest diamond ever discovered was 3,106 carats.
