A type jade (A jade)


natural, untreated jadeite jade
only beeswax is used to fill the stone's microscopic surface pores
 

Dyed jade has existed but in early 1980's a new kind of jade appeared in the markets of East Asia. This material had a light, bright body colour and good translucence. A "spidery" texture could be noticed when viewed under magnification. Prices were too reasonable for such 'appearant) quality. This marked the beginning of what has since been called "B" jade, which continues to be by far the most common form of treated jade.
