Diamond Clarity

A diamond’s level of clarity depends upon both external and internal properties.
  

The internal properties are called inclusions. The most prevalent inclusions are:

Crystals

These are mineral deposits trapped inside a diamond.

Clouds

These are hazy areas commonly produced by crystals far too small to see under 10x magnification.

Feathers

These are breaks or cracks within the diamond

The external properties, or surface irregularities, are called blemishes, for example a blemish could be a scratch on a diamond’s surface.
 

Obviously the fewer inclusions and blemishes that exist then the better the diamond clarity. These diamonds are scarcer which makes them much more valuable.

How are diamonds graded for clarity?

 
The clarity grades range from Flawless to Included 3. The Included 3 grade have blemishes and inclusions that even the human eye can detect and it is not advisable to buy such diamonds.
