Type A jadeite is characterized by which of the following?

Type A jadeite is characterized as natural jadeite that is enhanced solely with a surface coating of wax. This treatment involves applying wax to improve the stone's appearance and polish, effectively enhancing its luster and depth of color without altering the composition or structure of the jadeite itself.

This method distinguishes Type A jadeite from other types, which may involve more invasive enhancements, such as the use of dyes or stronger chemical treatments. The key aspect of Type A jadeite is that it maintains its natural properties and integrity, making it highly prized among collectors and gem enthusiasts. The focus on minimal and less invasive treatment aligns with the often strict definitions in the gemological community regarding the classification of jadeite and its various treatments.
