1. Colombia

Colombia is the largest emerald producing area, and high-quality emeralds account for the majority of the world market; Chivor Mine and Muzo Mine are the two most famous emerald mines in Colombia: Chivor Mine was developed as early as 1537 , the emeralds it produces have a bluish tone, longer crystals, and fewer inclusions, so their brightness and clarity are higher than ordinary emeralds; the emeralds produced in the Muzo mining area are the most highly regarded, and the emerald crystals produced in the Muzo mine are shorter. , but the color has a higher saturation. One of the emeralds known as "Muzuo Green" is famous for meeting the strict requirements. It needs to have a deep emerald green with bluish light that is difficult to imitate. If it reaches the same quality as "Muzuo Green" As for the color, the authoritative identification agency GRS will note MUZOGREEN on the attached page of the certificate, or add an * after VIVID GREEN. The same color has not yet been seen in other producing countries, which shows the rarity of Colombian "Muzo Green" emeralds.

Due to the high iron content in the geology of the mining area, the emeralds produced are bright green or green with blue, and contain flaky biotite. Or columnar hornblende inclusions, slightly grayish in tone. The Mohs hardness produced in Zambia (7.5-8) is also higher than the hardness produced in Colombia (7-7.5), so it is suitable for cutting into smaller and high-quality gemstones.
