Muzo and Chivor are two of the most famous emerald mines in Colombia and the world, known for the exceptional quality of their gems. Muzo emeralds are distinguished by their intense, deep green color and high purity, making them highly prized in the market. Chivor emeralds, on the other hand, typically have a bluish-green hue and superior transparency, giving them a brilliant, crystalline appearance. Both regions produce emeralds with a hexagonal crystal structure and, in many cases, contain natural inclusions known as "jardines," which can increase their value by demonstrating their authentic origin.
