Where were trapiche emeralds first discovered?

Trapiche emeralds, characterized by their unique star or hexagonal patterns created by distinct growth lines, were first discovered in Muzo, Colombia. Muzo has a historical reputation as one of the premier sources of high-quality emeralds, and it is particularly known for producing these distinctive trapiche varieties. The geological conditions in this region allowed for the formation of these unique emeralds, making Muzo a significant location in the world of colored gemstones. The other locations mentioned, such as Coscuez and Sandawana, are known for emeralds but are not the original discovery site of trapiche emeralds. Zambia is also a notable source of various emeralds, yet it does not have the historical association with trapiche varieties that Muzo does.
