Inclusions in Emeralds

Inclusions in Emeralds

If you look at the emerald under a microscope, you can see that it contains various characteristic inclusions.

 

Studying the inclusions of natural emeralds suggests insights into the geological formation of their place of origin.The main component, "beryllium," is a rare earth element in the upper part of the continental crust.Emeralds are formed in an unusual environment where "Be" is combined with "Cr".The main production areas are Brazil, Colombia, Madagascar, Russia, Zambia and Zimbabwe.In these environments, minerals present in host rocks and rocks formed at the same time as emeralds can be inclusions.In addition, the technique of adjusting the color tone of emeralds during the generation process has continued since the ancient Greek era.

 

In contrast, synthetic and artificially treated emeralds often show inclusions that are evidence of an artificial growing or processing process.

The main artificial treatment of emeralds is to improve transparency.Make scientific adjustments to adjust the index of refraction of the stone.The trail of this treatment is often the flushing effect seen when examining stones under a microscope with flattened bubbles.As a result, artificial emeralds are more transparent than natural emeralds.
