The authenticity of jade

Answer 1

To identify the authenticity of jade, one could start from the following aspects:

** 1. Color **
1. ** Natural jade color characteristics **
- The color of natural jade was naturally formed. The color was natural and evenly distributed. For example, Hetian jade, a high-quality white should be warm and shiny, not a dazzling cold white, but a soft white with a "fat feeling." If a piece of jade was as white as a piece of paper, it might be a "fake white jade" that had been treated with whiteness.
- For jade and other jades, if the color was too thick, stiff, and not as natural as the color of natural jade, it might have been processed or forged.
2. ** Fake Jade Color Specialties **
- Fake jade was dry, dull, and lifeless. It was like jade that was made of glass. Its color was often too transparent and perfect, and it did not have the natural feeling of natural jade.

** 2. Hand feeling **
1. ** True Jade Touch **
- True jade had a certain density, and holding it in his hand would give him a corresponding feeling. For example, Hetian jade had a high density. When held in one's hand, it would have a heavy feeling, and it would have a slight cool touch. It would have a cold and warm feeling.
2. ** Fake Jade Touch **
- Fake jade might seem light when held, like a glass imitation of jade. It felt rough and almost did not have the cold feeling of real jade.

** 3. In terms of structure **
1. ** Observing the structure of the real jade with light **
- For Hetian jade, you can use a small flashlight or a mobile phone flashlight to observe the jade. There was a fiber interwoven structure inside the real Hetian jade, like layers of fat fibers.
- Different jades had their own unique natural structure when observed by light. For example, if the jade was processed by acid corrosion (B grade jade), some grid-like patterns that were not found in natural jade might be seen in the structure.
2. ** Fake Jade's structural characteristics **
- Inferior fake jade was either too transparent or the fiber structure could not be seen at all (for jade with fiber structure characteristics like Hetian jade).

** 4. Sound **
1. ** True Jade's Voice Attribute **
- Good Hetian jade would produce a crisp echo when struck, especially the best seed material. When struck, one could hear a long and deep tone. As for the other jade pieces, they were hung up with thin threads and knocked lightly with a hard object. The sound of the real jade was crisp and pleasant, and the aftertaste was melodious.
2. ** Fake Jade's voice characteristics **
- The low-quality fake jade was mostly a dull "plastic sound" or a metal-like "hard sound".

** 5. Other special identification methods **
1. ** Hetian Jade's Water Drop Test **
- The surface of Hetian jade was extremely dense and smooth. If a drop of water was dropped on its surface, the water drop would remain round and not spread easily. If it was a fake jade, the water droplets would disperse very quickly.
2. ** For the pore identification of Hetian Jade Seed Material (For Hetian Jade Seed Material)**
- ** Pore shape and size **: The pores of the natural seed material are traces left by running water. They are small on the outside and large on the inside. They have a certain depth and are shaped like the pores on human skin. They are delicate and smooth to the touch. The pores of the sandblasted seed were large on the outside and small on the inside, showing the shape of an open trumpet. In the beginning, the pores of the sandblasted seed were rough and shallow, but after improvement, they were too small.
- ** Direction and angle of erosion marks **: Natural seeds are formed by being washed in the river for a long time. The erosion angle of each position will change according to the shape of the original stone, and it looks smooth and natural. The sandblasting machine carried out a flat impact, and the angles of the pores were often the same. Even if the shape of the jade stone changed at the corner, the sandblasting marks remained the same, which seemed unnatural.
- ** The relationship between the degree of pore exquisiteness and jade quality **: The finer the jade quality of Hetian seed material, the finer the pores. The pores of different parts of the natural seed material have significant differences. Even if the quality of the jade stone was poor, the pores might be processed to be extremely fine. The appearance of overly well-proportioned pores on the raw materials should be vigilant.
- [Over-naturalness: The pores of the natural seed material are naturally formed in the water. The changes are smooth and natural. There are no traces of deliberate creation.] Although the sandblasting imitation seeds could be adjusted, the changes were step-by-step, and the details were often abrupt.
- ** The relationship between the skin color and the pores: The skin color of the natural seed material and the pores are produced simultaneously, and it is difficult to distinguish the order. The surface skin color and the pores are integrated into one. Sandblasting imitation seeds were first sandblasted and then dyed. The skin color often floated above the pores, and sometimes there would be deposits in the potholes.
3. ** Hardness test (applicable to some jade)**
- When the jade was slid across the glass, the glass would leave obvious scratches, but the jade itself would not leave any marks. However, this method was not suitable for all jade, and it might cause some damage to the jade, so it needed to be used with caution.
