Type C jadeite is identified by which characteristics?

Type C jadeite is characterized primarily by its treatment process, which includes being dyed, often bleached, and sometimes impregnated with wax or polymers. This type of jadeite is not solely natural; the treatments are applied to enhance its color and appearance, making it more appealing in the market. The bleaching process helps to lighten the natural color, making it more suitable for dyeing to achieve vibrant hues. The use of wax or polymers fills in surface imperfections and enhances the shine of the stone.

Understanding the identification of Type C jadeite is crucial for anyone involved in the colored gemstone industry, as it directly impacts the value and authenticity of the stone. Recognizing its treated nature informs buyers and sellers about the potential quality and price points of the jadeite they are dealing with, differentiating it from natural, untreated jadeite (often categorized as Type A) or jadeite that has been given other forms of treatment or enhancements.
