Emeralds are green precious gemstones that are mined in various geological settings. They are minerals in the beryl group of silicates. For more than 4,000 years, emeralds have been among the most valuable of all jewels on Earth. Colombia, located on the continent of South America, is the country that mines and produces the most emeralds for the global market. It is estimated that Colombia accounts for 70-90% of the world's emerald market. While commercial grade emeralds are quite plentiful, fine and extra fine quality emeralds are extremely rare. Colombian emeralds over 50 carat can cost much more than diamonds of the same size.
The Colombian departments of Boyacá and Cundinamarca, both in the Eastern Ranges of the Colombian Andes, are the locations where most of the emerald mining takes place.
Although the Colombian emerald trade has a rich history that dates as far back as the pre-Columbian era, the increase in worldwide demand for the industry of the gemstones in the early 20th century has led prices for emeralds to nearly double on the global market. Until 2016, the Colombian emerald trade was at the center of Colombia's civil conflict, which has plagued the country since the 1950s.
For thousands of years, emeralds have been mined and considered one of the world's most valuable jewels. The first ever recorded emeralds date back to ancient Egypt, where they were particularly admired by Queen Cleopatra. In addition to their aesthetic value, emeralds were highly valued in ancient times because they were believed to increase intelligence, protect marriages, ease childbirth, and thought to enable its possessor the power of predicting future events.
An ancient Colombian legend exists of two immortal human beings, a man and a woman—named Fura and Tena—created by the Muisca god Are in order to populate the earth. The only stipulation by Are was that these two human beings had to remain faithful to each other in order to retain their eternal youth. Fura, the woman, however, did not remain faithful. As a consequence, their immortality was taken away from them. Both soon aged rapidly, and they eventually died. Are later took pity on the unfortunate beings and turned them into two crags protected from storms and serpents and in whose depths Fura's tears became emeralds. Today, the Fura and Tena peaks, rising approximately 840 and 500 meters, respectively, above the valley of the Minero River, are the official guardians of Colombia's emerald zone. They are located roughly 30 km north of the mines of Muzo, the location of the largest emerald mines in Colombia.
