What does diamond clarity mean?

Diamond clarity can be expressed by the grading scale providing a relative ranking. A diamond's clarity grade considers factors such as size, nature, position, colour and quantity of imperfections visible under 10x magnification.

To evaluate diamond clarity, gemologists examine the lab-grown diamond under 10x magnification.

How is diamond clarity determined?

There are a few different ways to determine the clarity of a lab-grown diamond.


The first way is to use a loupe which is a 10x magnification tool. It is used to inspect the lab-grown diamond’s surface for flaws.

SI: Slightly Included (SI1 & SI2)


It has noticeable inclusions that can be seen under 10x magnification.

 

I: Included (I1 & I2)


It has large inclusions that are visible under 10x magnification. Generally, the beauty of the diamond is affected at this clarity grade or below.

 

F: Flawed


It has many inclusions that can be seen without 10x magnification.


Are lab-grown diamonds better clarity?

 

Many people choose lab-grown diamonds for their clarity. They prefer to buy a lab-grown diamond with a clarity grade of VS or better than VS.
