The word diamond derives from the Greek word ‘adamas’ which means invincible or indestructible.
A law in 13th century France decreed that only the King could wear diamonds.

The Earth is estimated to be 4.5 billion years old: the oldest diamonds are believed to have been crystallised around 3.3 billion years ago.
Diamonds form about 100 miles below ground and are carried to the Earth’s surface by deep volcanic eruptions.
Diamonds form the hardest natural substance found on Earth and can only be scratched by another diamond.
To produce a single one-carat diamond, 250 tons of earth will be mined.
The largest diamond ever discovered was the Cullinan diamond which weighed an amazing 3106 carats, or 1.33 pounds. Discovered in 1905 in South Africa, the mine’s owner and the South African leaders gave the diamond to King Edward. The Cullinan was eventually cut into nine large diamonds and 100 smaller ones: the three largest of these are on display in the Tower of London as part of the British Crown Jewels.
