Jade has different "colors", so be careful when spending money

The formation of jade can be divided into two stages:

1. The stage of forming the "bottom", which is called the diagenetic stage in geology

2. The color formation stage, which is called the mineralization stage in geology

How the chromium-containing solution enters the second stage is a very important issue that has a great impact on color quality.

Some jades are worth tens of millions, while others are worth only tens of thousands. This is related to its color, type, and quality. The way that jade green is formed largely determines the relationship between jade color, type, and quality.

Analyzing from the raw materials, the color of jadeite can be divided into three types: root color, group color, and bean color.

1

Root color jadeite——color formed by filling

Root color jade

1. Jadeite with bright color, full water head and fine texture is root color

2. The root color is formed by filling method.

3. The chromium-containing solution enters the jade along the existing rock cracks, crystallizing as it flows. The dynamic crystallization is mostly fibrous.

4. The formation of filling-type root color is due to the direct precipitation of minerals after the chromium-containing mineral liquid comes into contact with solid jade. The cooling speed is relatively fast, resulting in a finer texture and more uniform color.

5. Crystals formed by filling are often arranged in a direction parallel to the extension direction of the cracks. Crystals formed by filling are often thinner and more transparent.

6. The green color formed by filling often has no exchange relationship with the surrounding jade "bottom", so the boundary is relatively neat and clear.

Group color jadeite——color formed by replacement

Group color jadeite

1. Group color jadeite is a color formed by substitution, that is, the color formed by mutual replacement, distributed in irregular clusters or spots.

2. The color shape is irregular, and the boundary line between the color and the base is irregularly jagged.

3. The crystals formed by replacement are generally not oriented, with poor light transmittance (compared with the root color), and often form jadeite with color but no species.

4. Under the method of replacement formation, there will always be some unreplaced surrounding rock ("bottom") in the ore (green). This is the reason why the group-color jadeite cannot be full color.

5. The crystal grains of group-colored jadeite are usually coarser and the color is darker.

3

Bean-colored jadeite——color formed by penetration

Bean-colored jadeite

1. There is a kind of green that is formed by both filling and replacement, forming a green color that looks like fine veins are impregnated.

2. There is also a large area of ​​green formed by infiltration, but the color is not concentrated enough and is rather scattered.

3. The color formed in this way is most common in coarse bean-type jadeite, and the crystal grains are coarser.

4. Bean-colored jadeite is mostly used to make bracelets because of its large size.

5. The reasons for the color formation of jade in nature are very complex. In some cases, it is formed by staggered formation, and root color can also appear in bean color.

To sum up, if you can understand what type of color a finished product belongs to, you will have a professional basis for judging the value of a piece of jade.

The characteristics of root color jade are fine quality, good water head and uniform color, so it is very valuable.

The round-colored jadeite has medium-sized particles, medium water content, and darker color. It is second most valuable. The most common ones include white-based green.

The grains of bean-colored jade are coarser, the color is not concentrated, it often appears in large areas, and its value is lower.
