How to determine the quality of a diamond

They say diamonds are a girl’s best friend. It is not every day that you buy diamond jewelry, so if you are lucky enough to be considering buying one make sure you know the quality of what you are buying.

The quality of a diamond is measured by the 4C’s: color, carat, clarity and cut.


This is the degree to which the stone is colorless. Diamonds come in colors ranging from colorless to yellow, with the most valuable being the colorless ones. It is graded from D to Z with D being absolutely colorless and the most expensive.


A carat is by which the weight of a diamond is measured and 1 carat is equivalent to 200 milligrams. Each carat has 100 points. The price of a diamond goes up with its size as the bigger diamonds are rarer then smaller ones.


Clarity is the presence of flaws or inclusions in diamonds. The rarest and the most expensive ones are ones with no flaws and graded as F1 (flawless) or IF (internally flawless). The other grades are VVS, VS and S.


This is the shape of the diamond with different cuts reflect light in different angles creating the brilliance.
