What is a diamond?

Diamonds are formed below the earth’s surface when at least 70,000kg of pressure per centimetre is combined with temperatures exceeding 690°F. A volcano would then bring the diamonds to the earth’s surface where they can be mined. A perfect diamond is the result of the combination of those factors, making them a rare find – and expensive to buy too!

What are the four C’s?

Cut:
The cut is typically considered the most important of the four Cs. Cut, not to be confused with shape, focuses on how the diamond is actually cut – the more facets (flat surfaces) cut into the diamond the better, as they allow the light to pass through contributing to the sparkle.

Clarity:
The clarity describes the purity of the diamond. A jeweller can spot impurities, such as blemishes and flaws, with a special magnifying tool called a loupe. The fewer flaws and imperfections there are the more valuable the diamond is.

Colour:
Diamonds are available in a range of colours. Traditionally colourless or ‘white’ diamonds where the most popular as they have a brilliant sparkle, but more recently coloured diamonds are growing in popularity, including yellow, pink and champagne coloured stones.

Carat:
The carat describes the weight of the diamond. Each carat weighs 200mg.
