The 4C's of a Diamond

Carat:

The weight of a diamond (and other precious stones) is measured in carats. It is the first and most crucial ‘C’ that dictates the Value and Rarity of a diamond. The larger the stone the higher the rarity and value of the diamond.

Color:

The Color of a diamond spans from Colourless (White) to Yellow, Brown, and more. With Colourless (White) Diamonds being graded from D-N and moving into Light (N-Z). High end Rare fancy on request, Red, Green, Blue, Pink, etc.

Clarity:

The Clarity of a diamond is determined by the number and intensity of the inclusion ranges from Flawless (FL) to Inclusion (I). With Flawless (FL) and Internally Flawless (IF) being the rarest and most valuable clarities. Followed by Very Very Slight Inclusion (VVS) and Very Slight Inclusion (VS) which are difficult to detect even under 10x magnification. Slight Inclusion (SI) is easily detected under 10x magnification, but not easily detectable by the unaided eye, Inclusion (I) detectable under magnification and visible by the unaided eye.

Cut:

The Cut spans from Excellent to Good and directly affects the Brilliance & Fire of a Diamond. A combination of Excellent-grades for Cut, Polish and Symmetry (i.e. Triple-Excellent) denotes the best cut.

In case of Fancy Shapes, Excellent is the highest grade for Cut, Very Good is a medium grade and Good is the base grade. The better the cut, the better the Performance in brilliance.
