Diamonds are naturally occurring chunks of carbon whose atomic structure makes them the hardest substance on the planet and allows them to handle light in a way that has captured the imagination for centuries.
Today, they are the best known of all precious gemstones and have been the popular choice for engagement rings for centuries.
Diamonds that have the natural properties of size, and the colour and clarity to be desirable as gemstones are very rare, but how do you define these qualities and how does it help when buying diamonds?
99% of the time when we talk about diamonds colour, we are talking about white diamonds and the slight variations between them. Diamonds come in many colours and these are known as fancy colours but, although these are fascinating, they are incredibly rare, expensive and not the subject of this article.

White diamonds are graded on a scale from white to yellow. White is the best and most desirable and yellow being the least. The scale goes from D to Z. So when you hear about a D coloured diamond, somebody is talking about a diamond that is of the whitest colour we know of and most probably, a very nice and valuable stone.
The clarity of a diamond means how many natural inclusions a diamond has. Until recently, in the world of commercial diamonds, diamonds with inclusions visible to the naked eye have rarely been used, though trends change and diamonds with largest visible diamonds, often marketed as salt and pepper diamonds are popular.
Again, there is a scale on which the clarity of diamonds is graded. These goes from F to I3, F means flawless and again these are the rarest and most valuable of stones.
