&Because the "Jade Cong King" is so famous, when people mention Liangzhu jade, they will inevitably think of Liangzhu Jade Cong.
Its lingering shadow can always be seen in antique trading venues of various sizes. In fact, jade of this exquisite grade is absolutely impossible to appear in private transactions. The reason is very simple: there are too few items. Therefore, whenever you see a jade cong of this level, no matter how high or low you are, you should not spend money to collect it. This is the author's advice.
As an ordinary collector, you still have the opportunity to see or collect Liangzhu jade congs that were made by master craftsmen. The author summarized the Liangzhu culture jade congs
When appraising the jade congs, you only need to keep one thing in mind: no matter whether it is authentic or not, Neither the cooked pits handed down from ancient times nor the raw pits unearthed will be as beautiful as the photos in the description.
If they really look beautiful, you have to be more careful. The authentic Liangzhu jade cong needs to have the following characteristics :
.The decorative picture is based on the angle line between each two planes of the cong as the axis of the picture, and the same style of decoration is symmetrically carved. For example
For example, the angle line carves out the nose of an animal face. , mouth, and two eyes carved on the planes on both sides.
.The form of the combination of gods and beasts is quite strict and standardized. Specifically, a jade cong can be divided into several sections, and each section is divided into two groups: the first group
carves the facial patterns of gods and humans; The second group carves animal masks, and this combination is never chaotic.

. It is divided into two types of decoration: complex and simplified: the eye sockets on both sides of the complex type are composed of three groups of concentric thin lines divided by three groups of thin negative lines, and the middle eyeball is reduced
The bulging eyes in simplified form can only be summarized as a circle with a single negative line.
.The upper and lower two sets of patterns are respectively raised by the method of reducing the ground level to protrude the main part of the pattern. The ground reduction is polished very smoothly.
.The fine Yin lines are very shallow with a knife. According to traditional saying, the thin negative lines of the Liangzhu Culture were carved with so-called "hippocampal teeth". Regardless of whether it is true or false, we can observe through a magnifying glass that the knife marks are shallow and uneven. The complex lines have a macroscopic feeling of "fineness", but upon closer inspection, there are inevitably obvious irregularities caused by manual work. This is the characteristic of the genuine article.

For general collection transactions, jade congs are mostly in the size of two or four sections. The identification of this kind of jade cong mainly involves using a magnifying glass to carefully observe the line features of the animal's face. Due to the soft texture of the jade used in the Liangzhu Culture, the detailed lines are easily worn away or blurred. This relationship between vagueness and complete disappearance and clear existence is natural. In this kind of relationship, the product will act extremely unnaturally. At the same time, we should also pay attention to the relationship between the bas-relief and the shovel. As for the color, shape, etc., for counterfeiters, they can generally do it.

The above two sets of pictures are partial comparisons of authentic and fake animal mask patterns taken by the author. It can be clearly seen that the negative lines of the fake Liangzhu Culture jade cong are not only
clear, but also reveal The cutting speed of the knife is very fast, and the negative lines are clear and smooth, which are the marks carved by sharp tools.
