The emerald trade in the region was a trade of masses, very wide and very lucrative, until the control of big Emerald companies changed. Emeralds were then all bought by the same owners of the companies leaving few gemstones for sale to regular traders, eventually the trade went from thousands to a few very wealthy hundred. Despite the fact that most of the emeralds from Muzo are bought by a few number of traders, Muzo emerald gemstones are still a huge percentage of the emeralds traded in Bogota, a place in which the change in the control of the mines in Muzo had not such a negative impact.
Muzo emeralds are known for their beauty, and within the trade they are known for their color and size, given that many of them do not have such an outstanding crystal clarity, although many emeralds extracted from Muzo have shown exceptional clarity, this is not a common characteristic within Muzo Emeralds, unlike emeralds from Chivor or Gachala which are known for being the clearest of them all.
Muzo emeralds are widely popular within international traders because of the longevity of deposits in the area and also because in the past when a Colombian trader sold an emerald to an international trader they use to say the gemstone was from Muzo, that happened for various reasons, one of them was because they did not know the true origin of the gemstone and because they thought they could sell the gemstone at a higher price if the buyer thinks it is from Muzo.
