WHAT ARE THE 4 C'S?
The Four C’s – Carat, Cut, Clarity, and Color – are the international standards used to evaluate a diamond’s quality.
CARAT
Carat describes a diamond’s weight. One carat equals exactly 0.20 grams and is divided into 100 points for maximum precision. Carat indicates the weight, while cut and proportions determine how large the stone appears.
COLOR
Color indicates how colorless a diamond appears and is graded by GIA on a scale from D to Z.
D represents the pinnacle – a completely colorless stone – while the scale gradually moves toward subtle hints of yellow or brown at Z.
CLARITY
A diamond’s clarity refers to the presence of natural inclusions (internal characteristics) and blemishes (external characteristics), formed during its creation deep beneath the earth’s surface. These details can vary in size, number, position, and visibility, and are assessed on a scale developed by GIA (Gemological Institute of America). The scale ranges from Flawless (FL), where no imperfections are visible even under 10x magnification, to Included (I), where flaws are visible to the naked eye. Inclusions may affect the way light reflects within the diamond, influencing its brilliance and overall beauty.
CUT
Diamonds are renowned for their exceptional ability to capture and reflect light. When we speak of cut, it is not only the shape – round, oval, heart, marquise, or pear – but the craftsmanship behind it that defines the stone’s beauty. A perfectly executed cut requires mastery of proportions, symmetry, and polish, where each facet interacts precisely with the light. The result is the diamond’s brilliance – its intense white sparkle – and its fire, the unique play of coloured flashes.
