What is a diamond?

Diamonds are developed below the Earth’s surface at a temperature exceeding 690°F, as well as this extreme heat, there also needs to be at least 70,000kg of pressure per square centre metre for the diamond to form. These formed diamonds are then brought to the Earth’s surface through a volcano – a perfect diamond requires all these factors to come together in one place, making diamonds a rare find – hence their price!

What are the 4 C’s?

Cut:
The cut is widely considered to be the most important of the 4 C’s when it comes to diamond grading. Cut is exactly that – the way in which the diamond has been cut – and isn’t to be confused with the shape of the diamond. For a diamond to sparkle it needs multiple flat surfaces – known as facets – for the light to bounce from and pass through to create that special twinkling that only a diamond has, the more that have been cut into the diamond, the more sparkle there will be.

Clarity:
The clarity describes how pure the diamond is – each stone is unique and can contain blemishes or other imperfections. The clarity is determined through the use of a jeweller’s tool called the loupe and the fewer imperfections, the more valuable the diamond.

Colour:
Traditionally colourless diamonds were the most sought after as this gives the diamond a clear and sparkling look. However in recent years, yellow diamonds and other coloured diamonds have been becoming an increasingly popular trend.

Carat:
The carat describes the weight of the diamond, with a one carat diamond weighing 200mg.
