Diamonds are found in all colours of the rainbow, from colourless and transparent stones to ink black ones. Varying degrees of yellow or brown colour is common in most of the diamonds and a slight difference in colour can make a substantial difference in value. A truly colourless diamond is extremely rare and considered the most valuable. It allows most light to pass through the stone and create the most brilliance. The colour scale goes from D to Z, with D being the most white and Z being the most yellow. To learn more, click on Diamond Color.
Clarity is a term used to describe the absence or presence of flaws inside or on the surface of a diamond. In other words, the clarity of a diamond refers to the clearness or purity of a diamond. When these flaws/marks occur internally, they are called inclusions and when these flaws/marks occur on the surface, they are known as blemishes. These slight flaws make every diamond quite unique but they also do affect the beauty and value of the diamond. Diamond Clarity Grading Scale grades a Diamond with any of the following grades: F (Flawless), IF (Internally Flawless), VVS1 - VVS2 (Very, Very Slightly Included - 1 & 2), VS1 - VS2 (Very Slightly Included - 1 & 2), SI1 - SI2 (Slightly Included - 1 & 2), I1 - I2 - I3 (Included - 1, 2 & 3).

The term "Carat" refers to the weight of a diamond. Each carat is divided into 100 points. Therefore, 1/4 carat diamond is considered as 25 points and 1/2 carat diamond is considered as 50 points and so on. When diamonds are mined, large diamonds are discovered rarely in comparison of small ones, which make large diamonds much more valuable. For that reason, the price of a diamond rises exponentially with its size. So, a 2 carat diamond of a given quality is always worth much more than two 1 carat diamonds of equal quality.
