Cut

Cut is the most important of the 4Cs, influencing how a diamond reflects light. A well-cut stone has ideal proportions and symmetry, creating the brilliance and sparkle that make diamonds shine.

Colour

Colour refers to the natural hue in a diamond, ranging from colourless to light yellow or brown. The less colour a diamond has, the higher its value. Truly colourless diamonds are exceptionally rare and highly prized for their brilliance.

Clarity

Clarity measures the presence of natural inclusions and surface blemishes in a diamond. These tiny marks make each stone unique, reflecting its natural origin and individuality.

Carat

Carat refers to the weight of a diamond and is often associated with its size. As carat weight increases, so does the rarity and value of the diamond.
