Many jewellers refer to these characteristics as inclusions. For this reason, I1 represents “Included 1.” Lower clarity diamonds fall into either I2 clarity or I3 diamond clarity, the latter of which represents the lowest official clarity grade possible for a diamond.
Are inclusions good in a diamond?
Likely, most jewelers will never see them. However, most inclusions are unnoticeable by just looking at a diamond and may need a high magnification microscope to see them. Such imperfections do not affect the clarity of the diamond. However, large inclusions lead to a low-grade clarity diamond, which is less valuable.
What does slightly included diamond?

Clarity will affect how the diamond sparkles and looks under light — and fewer inclusions means the diamond will shine more brightly under the light.
Can an inclusion in a diamond get worse?
Once formed, inclusions don't grow or change; they can sometimes be removed through clarity enhancement techniques. The most commonly seen inclusions are in the form of black spots (carbon that hasn't crystallized), lines, small crystals (visible as pinpoints or clouds), and cracks.
What causes diamond inclusions?
Inclusions are small imperfections within a diamond that are created due to the extreme pressure and heat that diamond's experience when they form. Almost all diamonds have inclusions; in fact, perfectly flawless diamonds are so rare that most jewelers will never see one.
Which diamond clarity is best?
flawlessThe highest clarity grade for a diamond is FL, or flawless. The GIA only ever grades a diamond as flawless when it has no inclusions or blemishes that can be seen by a skill grader, even if it's viewed under 10x magnification.
What is a decent diamond quality?

It is said that during the formation process, the diamond must have stopped developing due to poor conditions, and as it resumed (even for a thousand years later), the twinning wisps were formed.
