Too much of perfection is something that Mother Nature does not go by. What she creates is perfectly imperfect. Natural Gemstones are the absolute examples of imperfect beauties. Gemstones, in whichever flaws- internal or external- are superb to look at and make for the perfect jewellery.
Some of the external flaws include scratches, blemishes or chipped edges. Although these factors affect the value of the gemstones, they are sometimes preferred by buyers. Internal flaws are rather interesting in the case of gemstones. They are formed within the formation. They are called inclusion.
Interestingly because of the varied inclusion that these gemstones have, none of them is alike. Whether it is the weight, dimension, colour, the impurity or the structure, these gemstones have a lovely hue anyways.
There Are Different Types Of Inclusions
This inclusion could be fossils, mineral presences or even host mineral inclusions that find a place inside the gemstones.
Some such aventurine and rutile deposits in sapphire. Some of the other inclusions include needles, minerals, and crystal growth such as calcite.
Some gemstone specimens have unique internal cavities within their structure. Ideally, these cavities are very small. However, that is not the ideal situation. These cavities are often occupied by a liquid, such as water or saline. These cavities can also contain liquid carbon dioxide or natural hydrocarbon compounds.
Interestingly, Topaz stone, Beryl and Quartz are some of the gemstones that are known to have liquid inclusions and opal have an extremely high-water content. This can amount to 30% liquid silica gel or hydrated silicon dioxide. This liquid is responsible for producing the vivid rainbow hues in opal’s play of colour.
These inclusions appear as bubbles within the solid structure. As with liquid inclusions, gaseous inclusions are gases that occupy a cavity within the gemstone.
It seems as if a gemstone, the same as the host, has formed inside the original stone. It is because the gemstone would have started forming, paused and re-started forming again. Once that is done, it envelopes the original structure forming an optical inclusion.
It is difficult to see inclusions with the naked eye unless seen under the microscope. Seeing under the microscope also helps in identifying the type of inclusion- whether crystal or bubble. It must be mentioned here that crystal inclusions indicate a natural garnet while bubbles indicate cheap synthetic.
All About Inclusion In Gemstones
Inclusion in gems is important in different ways, which solidifies the understanding of the gems. It has been categorized in the following ways:
• Inclusion as a flaw for gem’s clarity
• Inclusion as a source of information
• Inclusion as beneficial components
What Are Considered To Be Inclusions:
• Uneven colour distribution
• Fissures and fractures
Buy gemstones of your choice from online retailers and shops. However, ensure that they provide you with gemstone certificate of authentication. This will tell you how natural is your gemstone.
Remember, synthetic gemstones can have an adverse effect on your overall well-being. You could also give the gemstone for verification at the gemological institute.
