How to correctly distinguish the shell of jadeite original stone

1, look at Songhua. The pine flowers on the original jadeite stone shell are all green, like dried moss, one by one. The distribution of pine flowers is also varied, with different sizes and colors, and the rare one is white pine flowers.

2. The jadeite in this shell is mostly tight and smooth, which is a symbol of poor internal meat quality, loose and sparse, and changeable. The white salt sand skin looks similar to the yellow salt sand skin, but the color is changed to white. The surface is covered with sand and has a strong graininess, which is the best performance of white sand.

3. Black sand: The skin is black and covered with a layer of wax shell. Black sand is produced in almost all sites, but the best quality is the black sand in Pagan and Nanqichangkou, which is also the shell feature of high-color jadeite. Old elephant skin: gray and white, it looks wrinkled and rough, like elephant skin. There seems to be no sand, rough hands.
