The 4C's of diamonds

Diamonds are the most precious and rarest stones on earth, a diamond is nature's gift and no two are ever the same. Every diamond's price, rarity and beauty are determined by the combination of four characteristics: cut, colour, clarity and carat, also known as the Four C's of Diamonds.

Cut

The Cut describes the proportions and angles of a diamond and determines its brilliance. A diamond reflects light from one mirror-like facet to another and projects the light through the top of the stone, this dazzling beauty is a direct result of the cut.

Colour

The colour-grading scale ranges from D to Z. The highest colour grade and whitest stone available is a D colour diamond. This is also the rarest colour grade, which translates to a higher value. Most diamonds have a slight hint of yellow and the diamond colour scale is based on the amount of yellow present in a diamond.

D,E and F – Colourless

G,H,I and J – Near Colourless

K,L and M – Faint yellow or brown

N through Q – Very light yellow or brown

S through Z – Tinted Colour

Clarity

Clarity measures the relative visibility of external blemishes or internal imperfections naturally occurring within a diamond, most are not discernible to the naked eye and require 10x magnification to become visible. Called inclusions, they are nature's fingerprint and make every diamond unique.

The clarity scale is divided into six primary categories:

FL - Flawless, no inclusions or blemishes of any sort under 10x

IF - Internally flawless, no inclusions and only insignificant blemishes under10x.

VVS1 - VVS2 - Inclusions are difficult to locate or see under 10x.

VS1 - VS2- Inclusions present less difficulty to located or see under 10x

SI1-SI2 - Inclusions are readily seen at 10x, although they remain invisible to the unaided eye when the diamond is viewed face up.

I1 - One or more inclusions or their effect, can be seen by the unaided eye.

Carat

As with all precious stones, the weight -and therefore the size -of a diamond is expressed in carats. One carat is divided into 100 "points" so that a diamond of 25 points is described as a quarter of a carat or 0.25 carats.
