Muzo is a mining area in Colombia and a famous emerald producing area. The emeralds in this mining area are of excellent quality and are synonymous with top emeralds, which are deeply loved by emeralds lovers, but Muzuo and Muzuo are different. Emerald is the color grade of emeralds, representing the highest quality emeralds produced in Colombia. Muzuo Green is a color grade. GRS, an international authoritative jewelry appraisal and testing organization, defines Muzuo Green as a more advanced color than bright green, which has a certain range of hue, saturation and lightness, and has certain requirements on cutting mode, direction and proportion. The most important point is that there is a requirement of origin and it must come from Colombia. It can be seen that the conditions for being rated as Muzuo Green are harsh.

Making wood green is also a symbol of top emeralds in the market, and it is also the pursuit of emerald investment collectors. Wood green is a color level, and emeralds from other places also have gems that can reach the color level of wood green. However, the name Muzuolv is limited by the place of origin, so emeralds from other places of origin cannot be rated as Muzuolv even if they reach the color level of Muzuolv. Now there is a term in the market: Wharton Green, which was put forward by Guild, a jewelry appraisal and testing institution. It also represents the highest quality emerald color. The biggest difference from wood-based green is that Wharton green has no restrictions on the origin, which means that emeralds from any origin can be rated as Wharton green as long as they reach the color level of Wharton green.

Wood green represents the best color and the highest quality place of origin, so as long as it is wood green, the price of jade is higher.
