A diamond’s 4 C’s represent the four main components of its beauty and structure: Cut, Colour, Clarity and Carat. When looking at a diamond, the eye perceives a balance of its characteristics and components, including, but not limited to, the 4 C’s.
CUT
A diamond’s brilliance is largely determined by its cut. An expertly-cut diamond with perfectly symmetrical and aligned facets will reflect light beautifully, leading to unrivalled brilliance. True expertise is required to create facets with perfect proportions that maximise light and increase a diamond’s signature sparkle.
CLARITY
Diamonds are created by tremendous heat and pressure deep within the earth. This thoroughly organic process means that virtually all diamonds contain internal inclusions and surface blemishes. Diamonds with fewer of these characteristics are deemed to have a higher clarity, ranging from FL, or Flawless, to I, signalling a number of inclusions.
COLOUR
White or colourless diamonds exist on a scale of many different shades, ranging from brilliant white to pale yellow. These subtle differences are graded on a colour scale from D (colourless) to Z (light yellow). Coloured diamonds, in hues of yellow, pink, blue, orange, green and red, for example, go beyond all other measures of rarity, and a graded based on their intensity and enticing depth of colour.
