Jadeite
Chemical composition: SiO2:58.28% Al2O3:23.11% Na2O:13.94% CaO:1.62% MgO:0.91% Fe2O3:0.64%, and also including other impurity metal, such as, Cr, Ni and so on.
Shape : Fibrous in shape to cause the body intensivly, the original raw material takes the form of lump, hypo-raw material is mostly emerald stones.
Color: Colourless , white , green , jade green , yellowish green , brown and red , lilac , pinkish-purple, among them green for " cui " and " Fei " to be red. It is because that Emerald color all due to the impurity of metallic element, such as including Cr , Ni for green , including Fe as red.
Physical performance : Hardness: 6. 5-7, proportion 3. 25-3. 36, commonly as 3. 33, the body of emerald lump is dense and wilful , glass gloss, opacity and even semitransparently.
Producing form to be divided:
The material of new mountain: It is meaning that produced in the original rock or grown the emerald originally. Its material jadeite doesn’t have rind or is called jadeite without epidermis .

MgO:23.83% Fe2O3:0.80%.
Shape: Fibrous dense into shape of lump, also take the form of riverbed cobble
Color: white ( including less impurity or purer ), sage green, hoar, green to be getting dark green which including a plenty elements of Fe, Cream-coloured , yellowish , yellowish green , brown , lilac and so on.
Physical performance : Hardness: 6-6. 5, proportion 2. 90-3. 02, it is usually 2. 95, fine-smooth and tenacity.
Producing form to be divided as below:
Original material: Mean growing the ore originally of nephrite
Mountain edge material: Mean the nephrite quarried in the riverbed.
Others : The original nephrite is not far away the Glacier carrying.
Main producing area: Xinjiang of China , New Zealand , Russia , Italy ,etc.
