Diamonds are calculated by its four Cs Colour, Cut, Carat and Clarity.
Colour:
Colorless diamonds are the most attractive since they allow the most refraction of light. Diamonds also come in a wide range of other colours such as red, blue, green and bright yellow. These are marked as Z+ and are known as fancy diamonds. Diamond starts its colour with the alphabet ‘D’.
D,E,F----->Colorless
G,H,I,J--->Near colorless
K,L,M----->Faint Yellow
N,R------->Very Light Yellow
S,Z------->Light Yellow
Cut:
Cut is most likely significant and demanding of the four Cs to understand. The brightness of a diamond depends a lot on its cut. The most accepted cut for a diamond is the round brilliant cut.
Carat:
Is the unit of weight for the diamond. A carat is further subdivided in 100 points (0.01 cart = 1 point). One carat is equal to 0.20 grams. Value per carat increases with carat size, because larger rough diamonds occur less regularly, In other words, 2 half-carat diamonds taken together will not cost as much as 1 one-carat diamond, as the one-carat stone is more rare.
Clarity:
It is very familiar for diamonds to be formed with little imperfections. These are known as ‘inclusions’. A diamond’s clarity ranking is strong-minded by the number, size, type and placement of the inclusions.
