What is a Diamond
A diamond looks like the clearest of crystal. It sparkles in the light and is ideal as a decoration in jewelry.

A diamond is made of carbon, the same substance as talc, the softest carbon known. The difference in hardness between the various carbons such as talc, gypsum, fluorite and diamonds is the way the atoms are arranged in the carbon. Diamonds are made under immense pressure and are the hardest of all the carbon substances.

The largest diamond ever found was the Cullinan Diamond in the Premier mine in South Africa in 1905. It weight in at a massive 3,106 carats, or 621.2 grams. This is 6.21 Kilos. It was cut into nine separate stones including the Cullinan or Star of Africa which weights 550.20 carats. This stone is mounted in the British Royal Scepter, part of the British Crown Jewels, and can be found in the Tower of London.
