The jadeite is natural Burmese jade. It is well known in the trade as 墨翠. It looks black, however, it is green when light shines through.Despite that, there is also a difference in quality. For a jadeite which is very translucent with even green seen under the light, it can be in thousands and above, depending on the size. Whereas for those that are less translucent, with little green seen under the light, they can be in hundreds and below.This piece is of good quality. Green can be seen at every part (thick and thin) of it when light shines through. It is translucent and clean. In addition, the guanyin is very well carved.
