What is diamond clarity?

" Clarity is the level to which a diamond is free from inclusions and blemishes. "

The inclusions are imperfections within the crystal structure, which are very difficult to see. Blemishes are surface damage to a lab-grown diamond’s surface.

A lab-grown diamond's overall quality and value are determined by the 4Cs - Cut, Color, Carat weight, and Clarity.

 The better the clarity, the less visible inclusions are.

What does clarity mean?

The clarity can be expressed by the grading scale providing a relative ranking. When we talk about the amount of clarity in a lab-grown diamond, we’re referring to the amount of these clarity characteristics that are present in it.

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

How is 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.

The second way is to send the lab-grown diamond to a gemological laboratory for testing. It will be inspected from the inside out and graded based on clarity. This clarity grade will be used to help determine the lab-grown diamond’s value.

When it comes to clarity grading, the higher the clarity grade, the less visible the inclusions are. It is accessed across 6 categories, and 11 specific grades, which are:

FL: Flawless

The best clarity has no inclusions or flaws that can be seen under 10x magnification.

IF: Internally Flawless

Lab-grown diamonds with this grade have no inclusions visible and are only minimal through 10x magnification.

VVS: Very Very Slightly Included (VVS1 & VVS2)

It has very small inclusions that are extremely difficult to see under 10x magnification.

VS: Very Slightly Included (VS1 & VS2)

It has minor inclusions that are difficult and somewhat easy to see under 10x magnification.

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.

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.

Lab-grown diamonds are often graded to VVS or better. So, if you prefer the highest clarity possible, a lab-grown diamond might be right for you.

Buying tips?

Clarity is essential because it is used to determine the value of a lab-grown diamond. If you’re looking for engagement rings, it is essential to understand the differences between each clarity grade and their prices.
