Introducing the 4Cs

The 4Cs - colour, clarity, carat and cut - are key when it comes to choosing your diamond, particularly if you are buying a diamond ring. It is the interplay of these characteristics that determines the value, rarity and beauty of your diamond.

Consider the importance of each of the 4Cs and you'll achieve the best mix to meet your needs and your budget. For example, you may decide on a diamond with a lower grade colour and less clarity in order to have a stone with a larger carat weight and a really good cut.
