An emerald is one of the most valuable gemstones in jewelry. It has been revered and treasured for more than 4,000 years by pharaohs, emperors and kings.
The name emerald comes from the Greek “smaragdos” and means “green stone”.
The emerald belongs to the beryl family, in Greek “beryllos” and means “green-blue stone.” In addition to the green variety, which is the emerald, the beryl family has other well-known varieties such as aqua blue or pink morganite. Emerald owes its color to traces of chromium, vanadium and iron in its composition, whose varying concentrations offer an extraordinary range of green, from light to dark intense with different shades, brown, yellow or gray.
Emerald hardness in the Mohs scale is 8, so it is consider a very hard gem, discussed above diamond has 10 on this scale.
It is a very hard stone, but very fragile at the same time, because on the inside we can find cracks fractures and inclusions. This feature makes it delicate when carving.
Small visible inclusions and fractures within the rock are the marks that occur when the stone is formed and often called the “garden” of the emerald. Through the typical “Emerald” carving (carved stepped equidistant) it is aimed to accentuate the color of the stone.
The country par excellence with the highest quality in the emerald is Colombia; in deposits Chivor and Muzo. Other countries that are major producers of emeralds are Brazil, Russia, Zimbbawe and Zambia.
Of all the producing countries, we can say without doubt that the more appreciated variety and better quality can be found in Colombia.
