About Diamonds

How are diamonds formed?

To provide a brief history around diamonds, the diamond is derived from the Greek word 'adámas' ("unbreakable"). Natural diamonds are formed at a high temperature at a depth of 87 to 120 miles inside the Earth. Diamonds are made of carbon. Volcanic eruptions bring the diamonds closer to the surface of the Earth which are then extracted by miners. Diamonds are first said to be discovered and mined in India between 3000 to 6000 years.

A diamond is a crystal that reflects light in a unique way. It disperses lights into all colours of the spectrum. Diamond is the hardest known natural mineral, and is an expensive mineral due to its natural properties of hardness, rarity and purity. The purer a diamond is, the more rare it is – hence also making it more expensive, too.

Interesting Diamond Facts

  1. The only way to cut a diamond is by using other diamonds. This was a fact that was discovered in the 15th century, showing that a diamond is 58 times harder than Corundum, which is the next hardest mineral on earth. However, diamonds are brittle – and will shatter if hit hard with a hammer.
  2. The world’s largest diamond is 3,106.75 carats uncut. This diamond was found in South Africa in 1905 – and is named the Cullinan. This particular diamond was cut into the Great Star of Africa – weighing 530.2 carats, which forms a part of the British crown jewels.
  3. A white dwarf star named Lucy is the biggest diamond in the universe. This star weights 10 billion trillion trillion carat – and is technically known as BPM 37093
  4. The diamond engagement ring tradition began in 1477. This is when Archduke Maximillan of Austria gave a diamond ring to Mary of Burgundy.
  5. Thousands of diamonds are mined each year as they are actually found in abundance. However, 80% of diamonds are not suitable for jewellery, so finding good quality diamonds are extremely rare.
