Inclusions are clarity characteristics enclosed within a gemstone. It is present in more or less every gemstone and appears in various shapes and forms. These natural inclusions usually occur during the formation of gems under or over the earth. They play an important part in the identification of a gemstone, whether natural or synthetic.
There is a common misconception that gemstone having inclusions are not good. That is not necessarily true. In colored gemstone like sapphire, ruby, garnet, etc inclusions of rutile needles create a beautiful star, also known as asterism phenomena. Because of the presence of these inclusions, the prices of gemstones with asterism increases ten-fold. So, inclusions are not bad. They are part of precious gemstones. Inclusions also help in identifying the origin of a gemstone. For example, small cloud-like inclusions that scatter light and distinct brush-stroke like inclusions are typical of a Kashmir Sapphire.
It is justified then to say that the gemstone inclusions bring value and adds to their beauty. They can rather turn out to be more valuable than you think!
Some external and internal flaws are found in gemstones. The flaws that occur on the outside due to external environmental factors are called external flaws. The examples are scratches, fractures and blemishes that might affect the appearance of the gemstone.
Flaws that are found inside the gemstone are called internal flaws or inclusions. Formed naturally, these natural inclusions define gemstone quality and provide insights into its origination.
Types of Gemstone Inclusions
An included crystal is a mineral crystal trapped within a gem as it grows. It can be a crystal of the same mineral as the surrounding gem or a different mineral. It might be angular or rounded or can be light, dark, transparent or opaque.
Sometimes, a gem might contain features that look like mineral inclusions, but aren’t. They’re angular and hollow, and usually contain a liquid or a gas, or both. These are negative crystals.
Some gemstones possess unique internal cavities that are filled with water or saline
2 Phase and 3 Phase inclusions
The liquid inclusion might contain a liquid and a gas which makes it a two-phase inclusion. If it contains one or more crystals, a liquid and gas, it’s a three-phase inclusion.
A long, thin inclusion that can be a solid crystal or a hollow tube that might be filled with liquid or gas.

Any hazy or milky areas that cannot be described as a feather, fingerprint, or included crystals or needles are known as Cloud.
