Getting to know the 4 Cs

A diamonds value, rarity and beauty are determined by 4 correlating factors, known as the 4 Cs, these are: colour, clarity, carat and cut. Before purchasing your diamond, it’s important to understand why two diamonds that may look identical are actually valued differently. This section will help you to understand the Cut, Colour, Clarity and Carat in more detail, and help when studying the diamond's brilliance, beauty and quality.


Diamond cut specifically refers to the quality of a diamond’s angles, proportions, symmetrical facets, brilliance, fire, scintillation and finishing details. We believe these factors hold the most influence on a diamond’s ability to sparkle, along with its overall beauty.


The colour of a diamond is measured by how white or colourless a diamond is. Depending on the diamond’s cut, carat weight and shape, the colour may vary among diamonds. An important aspect with colour is to determine whether it appears colourless in relation to its setting.


A Diamond’s Clarity grade evaluates how clean a diamond is from both inclusions and blemishes. Evaluating diamond clarity involves determining the number, size, relief, nature, and position of these characteristics, as well as how these affect the overall appearance of the stone.


The carat is a unit of weight, which measures how much a diamond weighs. This allows very precise measurements to the hundredth decimal place. We believe the importance of considering all these factors when deciding on your diamond.
