Diamond purity perfection is an essential characteristic that jewelers consider while searching for a perfect diamond. Suppose you are doing any search for diamonds. In that case, there is no doubt that you have heard the term 'inclusion.' Inclusions are minor imperfections within the diamond that arise from the process of diamond formation.

Naked eyes cannot realize inclusions. Most diamonds have inclusions, some with much larger inclusions, leading to low-grade clarity.

Types of Diamond Inclusions

Bearding Inclusion

Bearding results from improper diamond cutting technique, causing hair-like lines, blurry and a fringed appearance at the girdle, even extending to the surface of the entire diamond.

Feather Inclusion

This is a tiny fracture within the stone that gives the diamond a white featherlike appearance. Such fractures are very dangerous and can cause problems related to durability.

Pinpoint Inclusion

Of all inclusions, pinpoint inclusions are very common. They are minute black or white spots noticeable as pinpoint inclusion on the surface of the diamond. Such inclusions appear as dots and are primarily visible at 10x magnification.

Diamond Cavities

It's a small hole just quite similar to that of a tooth cavity on the surface of the diamond, though it's a rare case. Such gaps occur when an impurity on the table of the diamond has been removed during the process of diamond polishing. Once the inclusion is removed, a cavity is left on the surface, which is a threat to the carat weight and price of the diamond.


Diamond is the most rigid metal on earth. Despite their hardness, they can as well bruise. A bruise occurs when an external force has been exerted on the table of the diamond stone, leaving unnecessary cracks under the surface of the diamond.

Those diamonds with external inclusions are lowly graded, affecting the value and cost of the gem. If buying a diamond, be sure to inspect it before and after setting up in order to track any possible injury. Contact us For more information about diamond inclusions.
