The Emerald

 

Emerald is a beryl that gets its green color from chromium. Mineralogically, two varieties can be highlighted: the common beryl with a cloudy and poorly colored appearance and the noble beryl, transparent and with beautiful colors, to which the emerald belongs.

Until the 16th century the only known emeralds were found in Egypt. Later, with the conquest of America, the Spanish unveiled the precious emeralds that are produced in South America.

Emerald producing countries.

First of all, a clarification, since you have to differentiate between origin and provenance.

Origin means the country where the mine is located and origin is where it is marketed and handled. Thus, for example we can have an emerald whose origin is a mine in Colombia and its origin is India because it is here where it has been carved and commercialized.

The most important deposits in the world are in Colombia, where 55% of the commercialized emeralds are produced and also the best quality specimens emerge. The sites of Muzo, Coscuez and Chivor stand out.

The second producer would be Brazil with its Canaiba and Socotó mines, followed by Zambia and Pakistan.
