1, jadeite is common in the cross section of jadeite material, and the weight of the finished product is difficult to see. 2. Emerald is an important symbol to judge the authenticity of jadeite, but it should not be used to judge the finished product. 3. Anything that can be seen in the finished product shows that the structure of the object is very rough and the variety is very tender.

2. Jade bracelets have fluorescence, which is very rare. This is not fake, but caused by a substance in it. Sometimes, when we shake it, we will see a faint white light, very light. This is an optical phenomenon. Not every jade has it. Therefore, this is very rare.

3. There are many reasons for the fluorescence reaction of jadeite, including the following three situations: polishing powder residue. If there is purple polishing powder residue in the polishing process of purple jadeite, then this jadeite will have a fluorescence reaction under purple light, and the logo of "polishing powder residue" can be seen on the certificate.

4, colorless ice or glass jade earrings, necklaces, Yu Pei and bracelet products often have this phenomenon. Not every jadeite can appear, which is related to the pressure during the growth of jadeite. It can be regarded as a relatively rare phenomenon in jadeite, so no jadeite is definitely more expensive than jadeite.

5. The jade bracelet glows. The shiny thing is crystal. According to jadeite theory, crystal is the most important factor affecting seed moisture. The bigger the crystal, the worse the seed water. Due to long-term immersion in strong acid, the crystal has changed and no shiny crystal can be seen.
