Which treatment process commonly enhances the appearance of jadeite?

The treatment process that commonly enhances the appearance of jadeite is dyeing. Jadeite is a type of jade that can be treated to improve its color and overall aesthetic appeal. Dyeing involves the application of colorants that penetrate the stone, allowing for more vibrant hues and uniformity in coloration, which may not occur naturally.

While bleaching, heating, and polishing can alter the appearance of some gemstones, they are not standard practices for enhancing jadeite. Bleaching can remove imperfections or stains but is not typically used specifically for jadeite. Heating may enhance some properties in certain gemstones, but it does not apply to jadeite in the way that dyeing does. Polishing contributes to the stone's shine and smoothness but does not significantly change or enhance its color. Thus, dyeing stands out as the primary method used to enhance the visual characteristics of jadeite.
