Jadeite is composed of a variety of minerals and contains many components. The most abundant mineral in jadeite is jadeite. Its hardness is generally seven degrees. The hard and sharp tools will not leave traces on the jade, but some fakes. The hardness of jade is low, and the overall situation can be traced on it. The hardness of jadeite is also a way to identify true and false jade.
The main ingredient in the fine jadeite is jadeite, followed by omphacite and sodium chrome pyroxene. This emerald has a translucent texture and a warm color like water, making it ideal for making jade jewelry. Some of the main minerals in jadeite are omphacite, the color is very bright, and the jade has a black grain like tiger skin, but the transparency is not good.

There is also a jadeite main mineral is omphacite, the color dark transparency is not good, so the price of this jade is lower, because the surface light gives a greasy feeling, so it is become fresh oil green.
The hardness of jadeite is related to the formation of jadeite rock in jade. The magma inside the earth forms hard jade rock through crystallization. During the movement of the earth's crust, the jadeite rock is continuously stretched, and the crystal grains between jadeite are also combined. The hardness of the jade is getting higher and higher, and the hardness of the jadeite will be higher and higher. The final element is added to the hard jade ore, which is the color of the ore, which forms a beautiful jade. The hardness of glass is generally 5 degrees, and the hardness of jadeite is generally 7 degrees. Therefore, glass cannot be traced on the surface of jade. In fact, the hardness of jade cannot be used to evaluate the quality of a piece of jade. The hardness of nephrite is smaller than that of jade, but nephrite is also A kind of fine jade. Jadeite, which contains only jadeite, is the highest standard for jade in terms of density, hardness and refractive index.
