Types Of Diamond Inclusions

Diamond inclusions are usually known as the flaws that can be seen inside a diamond or other gemstone. This is because a diamond that displays inclusions cannot be considered as an Internally Flawless diamond. Since Internally Flawless gemstones are rare, you can expect inclusions up to an extent in most diamonds. Additionally, an Internally Flawless diamond will be really expensive, and hence, most people opt to choose diamonds that have small inclusions.

The flaws inside a diamond are actually like the fingerprints; it is one of the key characteristics, which specify the authenticity of a diamond. If you know well about the diamond inclusions of your sparkler, you will be able to identify your gemstone even from a pool of options.

When it comes to the clarity of a diamond, the inclusions that are not visible to naked eyes will not make much difference. However, the visible flaws inside a diamond do affect its sparkle and brilliance, as these inclusions tend to interfere with the light that passes through it. The worse thing is that the inclusions in a diamond will make it prone to shattering and chipping.

Note that not every type of diamond inclusions will affect the strength of a gemstone. So, it is crucial for you to have a thorough knowledge regarding the types of diamond inclusions so that you can choose a perfect stone for your engagement or wedding ring. Some of the common diamond inclusion types are given below.

Crystal and Mineral Inclusions

Some diamonds will be embedded with minerals and crystals in them. In most cases, the tiny crystal flaws will be visible only through a magnifier. However, if there is a large chunk of crystal inclusions present in a diamond, it will be visible to naked eyes and will affect the clarity of a gemstone.

Pinpoint Inclusions

If the crystals present inside a diamond are extremely small, it is known as pinpoint inclusions. Such crystals can be either dark or light, and can be seen individually or as a cluster. In case of cluster formation, those areas of a gemstone will display a haze effect. This will affect the clarity grade as well as the value of a diamond.


There will be some cracks in some diamonds, which resemble a feather. This type of diamond inclusions is known as feathers. You need not have to worry about the strength of a diamond if the feathers are small. Yet in case the inclusions extend to the areas that are vulnerable to accidental blows, such as the base or top of the gemstone, feathers can make that gemstone prone to shattering.
