Which treatment process commonly enhances the appearance of jadeite?

The treatment process that commonly enhances the appearance of jadeite is dyeing. Jadeite is often enhanced through the application of various colors to improve its visual appeal. This treatment allows different hues to become more vibrant or to create a specific color that may be more desirable in the marketplace.

While options like bleaching, heating, and polishing can affect the appearance of jadeite to some degree, they do not specifically relate to the common enhancements typically applied to jadeite. Bleaching may remove impurities but does not enhance color, heating may change the texture or transparency but isn’t directly aimed at enhancing color, and polishing improves surface luster but does not add or change color. Thus, dyeing is the most relevant treatment method for enhancing jadeite's appearance, making it a widely accepted practice in the industry.
