In jadeite classification, what does Type C refer to?

In jadeite classification, Type C specifically refers to dyed jadeite. This classification indicates that the jade has undergone a treatment process where dyes are introduced to enhance or alter its color. This type of jadeite may exhibit vibrant colors that may not occur naturally in the stone, making it visually appealing to consumers.

Dyed jadeite differs significantly from natural jadeite, which is left untreated and retains its original color and qualities. Bleached jadeite, while processed to lighten its color, is categorized separately and is often referred to as Type B. Old mine jadeite, on the other hand, indicates jade sourced from older or historical deposits and does not inherently relate to the treatment or classification concerning dyeing. Therefore, Type C's designation for dyed jadeite reflects its specific treatment process, setting it apart from other forms of jadeite.
