Inclusions – Their Influence on Gemstone Color

Inclusions are natural features that are often found in gemstones and can play a significant role in their color and overall appearance. In this article, we will explore the influence of inclusions on gemstone color and how they compare to lab grown diamonds uk.

What are Inclusions?

Inclusions are naturally occurring imperfections that are found within a gemstone. They can take many forms, including bubbles, cracks, and foreign minerals. Inclusions are created during the formation of a gemstone and cannot be removed without altering the stone’s natural appearance.

The Influence of Inclusions on Gemstone Color

Inclusions can have a significant impact on a gemstone’s color. For example, some inclusions can cause the gemstone to display a phenomenon such as asterism or chatoyancy, which can enhance its overall appearance and value.

Inclusions can also cause a gemstone to display a range of colors, depending on the angle at which the stone is viewed. This is known as pleochroism and is commonly seen in gemstones such as tourmaline and alexandrite.

In some cases, inclusions can cause a gemstone to display a less desirable color. For example, iron inclusions can cause a yellowish to brownish tint in otherwise colorless diamonds.

Inclusions and Lab Grown Diamonds UK

Lab grown diamonds have the advantage of being created in a controlled environment, which can reduce the presence of inclusions and other imperfections that can affect the stone’s appearance. Lab grown diamonds are also more environmentally friendly and ethical than their natural counterparts.

However, lab grown diamonds are not completely free from inclusions and may contain features such as internal graining or growth lines, which can affect the stone’s appearance and value. It is important to note that lab grown diamonds are not synthetic or fake diamonds, but rather have the same physical, optical, and chemical properties as natural diamonds.

The Role of Cut in Enhancing Gemstone Color

In addition to inclusions, the cut of a gemstone can also play a significant role in its color and overall appearance. A well-cut gemstone can enhance its natural color and brilliance, while a poorly cut stone can make its color appear dull and lackluster.

A skilled gem cutter can work with the natural features of a gemstone, including inclusions, to create a finished product that displays maximum color and brilliance. In some cases, a cutter may even use inclusions strategically to enhance a gemstone’s color or create a unique design.


Inclusions are a natural occurrence in gemstones that can have a significant impact on their color and overall appearance. While some inclusions can enhance a gemstone’s value and beauty, others can detract from its appearance. Lab grown diamonds in the UK offer a more ethical and sustainable alternative to natural diamonds, but are not completely free from inclusions or other natural features that can affect their appearance. The cut of a gemstone is also an important factor in enhancing its natural color and brilliance. Whether you are purchasing a natural gemstone or a lab grown diamond, it is important to work with a reputable and skilled dealer or jeweler to ensure that you are getting a high-quality product that meets your expectations.
