The Four C's

The true value of a diamond is determined by four factors, commonly known as the four C’s. Understanding how this influence the cost, the actual stone and your requirement for the diamond, will greatly enhance your experience when purchasing and the outcome of the setting.


Diamonds come in a wide variety of colours, which range from colourless, generally the most rare and expensive to yellow on the other side of the scale, which are more affordable. We like to think of these as drops from the sun and often very beautiful in their own right.

Grading, is done by internationally recognized diamond laboratories and the colour is denoted by a letter of the alphabet, starting at “D” all the way down to “Z”


Clarity denotes the number of inclusions (or flaws) in a diamond. The grading ranges from internally flawless (IF) to heavily included (I3). As diamonds are a natural product, it goes without saying that internally flawless diamonds are extremely rare and expensive.


The “cut and polish” of a diamond is dictated by the shape of the rough material harvested. The most popular and classic is the round brilliant cut, followed by the Princess cut, but for the more adventurous there are a wide variety of other cuts available. Feel free to ask our master jeweler about these on your next visit.


The unit for measuring the weight of a diamond is referred to as a “carat”. The word “carat” is derived from an Arabic word for the fruits of a Carob tree. Carob seeds were used as weights on precision scales because of their reputation for having a uniform weight. The bigger the diamond the more carats it will weigh.

All the above factors should be taken into consideration before buying a diamond. Your final choice is determined by personal preference and price.
