2. Diamonds in nature take anywhere from 1 billion to 3.3 billion years to form.

3. The word 'Diamond' comes from the Greek word 'adamas' which means 'unbreakable'.

4. A large, flawless diamond of over 99 carats is called 'a paragon'.

5. The largest flawless diamond is called 'The Paragon' which weighs in at a whopping 137.82 carats, and is a D-Class Flawless Diamond which was found in Brazil.

7. Some blue diamonds are known to be terrific semi-conductors.

8. The most common impurity found in gem quality diamonds is Nitrogen.

9. Every year around 26,000 KG (130,000,000) carats of diamonds are mined.

10. These have a value of around $9 Billion.

11. In addition to the 26,000 KG that are mined each year there are around another 100,000 KG of small, synthetic diamonds produced every year, mainly for industrial purposes.

12. There have been diamonds found in the United States in Montana, Arkansas and Colorado.

13. Since the 1870's when diamonds were first found in South Africa, there have been over 900,000 KG of diamonds extracted globally (4,500,000,000 carats).

14. Russia is now the world's biggest diamond producer, with approximately 20% of the world's production capacity. 15. The De Beers Company control around 40% of international diamond production, but their influence has actually waned from their heyday when they controlled over 80%.

19. There is a star in the Centaurus constellation which is thought to be 4,000 km across and which it is thought is made of compressed carbon, in other words, Diamond. If you graded this in terms of carats, then it would be Ten Billion, Trillion, Trillion, Carats.

The only 'problem' is that it lies fifty light years away!

The technical name given to this diamond star by astronomers is BPM 37093.
