"Bright" jade after being corroded by strong acid and strong alkali - B-grade jade

The problem of B-grade jade in the jade industry seems to have never stopped. No matter how fast the times progress and how sufficient the knowledge is, there is always a group of vendors who cheat ignorant consumers under the guise of integrity and cheapness, and there is always a group of consumers who have never understood the knowledge of jade but are particularly fond of it and suffer greatly from it.

Mr. Lu Xun once said in his short story "Call to Arms": "Either explode in silence or perish in silence." In view of this, Brother Xuan will talk to you about some basic knowledge about B-grade jadeite.

In the jade industry, people often hear three terms: A-grade jade, B-grade jade, and C-grade jade. Grade A refers to natural jade, grade C refers to dyed jade, so what is the grade B jade we are talking about today?

B-grade jadeite refers to low-grade jadeite bricks that have been cleaned with strong acids and alkalis to remove internal impurities and stains, making the originally inferior brick material jadeite become clear and translucent, and then the vacuum negative pressure method is used to inject resin, paraffin and other substances to fill the internal gaps. This makes the difference between low-grade jade and high-grade jade appear smaller. A low-grade jadeite that the manufacturer then sells as high-end jadeite to make high profits.

B-grade jade is mainly composed of natural jade, but some unscrupulous people use the method of "removing the dross" to make it into a kind of jade that has no difference in appearance from high-quality jade. The main reason why it can prevail in the market is that some people who love jade do not have enough knowledge about jade and its price is lower than that of high-end jade. A simple example is that for the same pair of shoes, when the appearance difference between the genuine and pirated ones is almost the same, there will always be people who are fooled unintentionally.

Anyone who has bought jade knows that no matter how big or small the jewelry merchant is, when you purchase jade, the merchant will proactively state that they will issue a jade certificate. At this time, if someone buys B-grade jadeite, and does not promptly re-inspect the jadeite jewelry after getting it and wears it for a long time, symptoms of skin discomfort such as itching in the wearing area may occur.

What to do if you purchase B-grade jadeite that has not been re-inspected and adverse physical reactions occur has always been a problem that bothers everyone?

People only realized later that they had been cheated and the jade they bought was not genuine. At this time, you must first take out the certificate issued by the merchant when you purchased it, and check it to confirm whether the jade in the jade certificate column is A grade or B grade, because if it is A grade, it proves that the merchant has deceived the consumer and passed B grade off as A grade. The situation can be reported and resolved through formal channels. However, if the certificate indicates that it is a B-grade product, then at this time, if there is no other evidence, many people can only swallow their bitterness in silence - they cannot express their pain in words.

Since the fillers used in making B-grade jadeite are mostly resin, the damage to the body of most people is not too great, but there will always be some damage. Furthermore, the reason why B-grade jade is hated by people is mainly because it deceives some people who truly love jade in a way that does not match its actual value. This kind of behavior may bring temporary benefits, but it will actually hit the entire jade market and those who love jade.

Finally, I would like to share with you some simple identification techniques for distinguishing A-grade jadeite from B-grade jadeite. First, check whether the density in the certificate is 3.33. The density range of jadeite is concentrated between 3.25 and 3.43. If the density in the certificate is less than 3.25, it is definitely not A-grade jadeite. Secondly, you can use a magnifying glass to observe the texture structure of the jade you purchased. A-grade jadeite has a smooth surface, small sand holes, and inverted triangles or polygons at the connection between the mineral crystal particles. B-grade jadeite has round, deep, and black sand holes and mineral spots. Finally, you can try knocking on the sound of jade. A-grade jade will have a clear and long sound if there are no cracks, while B-grade jade will have a dull sound. Of course, the best situation is to take some time to go to a regular institution for a re-examination. There are risks in playing with stones, so be cautious when buying jadeite.
