A diamond's value comes from four things, known as the four Cs.
Carat
A diamond's weight is measured in carats. One carat is 0.2 grams and is divided into 100 points, so a 30-point stone weighs 0.30 carat.
Colour
White diamonds are graded from D (colourless) to Z. The closer to D, the whiter and the rarer.
Clarity
Most diamonds carry tiny natural marks inside them. Clarity says how few and how hidden they are, from flawless (FL and IF) through VVS, VS and SI to I.
Cut
It is the cut that returns light to the eye. Good proportions and polish bring a stone to life. Common shapes are round, emerald, pear, marquise, oval, baguette, princess and radiant.
