Which jadeite type typically exhibits the highest level of value and quality?

Type A jadeite is recognized for exhibiting the highest level of value and quality among the classifications of jade. This classification indicates that the jadeite has not undergone any artificial treatment or enhancements. Type A jade is typically characterized by its natural color, clarity, and texture, which are important factors in determining the stone's overall quality and desirability. The absence of chemical treatments or dyes means that it retains its natural properties, making it particularly sought after by collectors and buyers.

In contrast, Type B jadeite has been treated through polymer impregnation to enhance its color and durability, while Type C jadeite undergoes both dyeing and treatment, which can diminish its natural beauty. Polar jade, although valuable, is typically assessed differently and may not reach the same prestigious status as Type A jadeite when considering jadeite specifically. Therefore, Type A represents the pinnacle of authenticity and quality in jadeite, contributing to its high value in the market.
