Emerald species, and then how to distinguish between kinds of old and new in emerald? The Emerald Square concluded that mainly depends on whether the emerald succulent delicate close. New pit jade material loose structure, and some like winter flesh, and some like chaff radish, their background more to creamy white, gray, light green, ore looks like coarse salt particles with the pressure in the the kinds of old jade Even head difference, the structure is still very close. How to distinguish between new and old species? I think it can be observed from 4:00:

    3, see grayscale, usually head to good old kind of jade always with a little gray If you hit the water, the kind of old and not a little gray feeling old kind of jade, the price is quite delicate, not a few thousand to solve the problem 's. (Of course, this price also depends on many aspects, such as the level of purchases of raw materials, finished products made carving, the size of the finished product, the work is good or bad, the finished shape the rules or not, as well as the inclusion, in short, than the average the old kind of jade expensive)

    4, see the fluorescent, good old water JADEITE sometimes feel Fasan Zhao a light inside from the Emerald soft connotation. I have not seen a new kind of jade from the light.
