How to quickly and easily identify the authenticity of jade

Today we received some idle jade from a jade friend who asked us to help recycle and convert it into cash. These jade bracelets had appraisal certificates when they were purchased by my friend, so when he sells them for cash now, he never considers whether they might be fakes, and only considers the price. I didn't expect to find out it was B+C goods the first time I received it. As a team of jade appraisers, we will teach everyone how to quickly and easily identify the authenticity of jade.

First, shine an ultraviolet fluorescent lamp on the jade in total darkness to observe whether there is fluorescence. This is a quick and simple identification method to distinguish whether the jade is dyed or injected with glue. A-grade jadeite will not have any fluorescent reaction under ultraviolet fluorescent light, at most it will be slightly illuminated by the bulb. However, B+C jadeite has a blue and white fluorescence under ultraviolet fluorescent light. This is the fluorescent reaction of epoxy resin, which is very obvious. As long as there is a fluorescent reaction under ultraviolet fluorescent light, no matter what color the fluorescence is, it means it is not A-grade jadeite.

Secondly, observing the luster of jade is a quick way to identify the authenticity of jade. Natural jade has a glassy luster, Hetian jade has an oily luster, Xiuyan jade has a waxy luster, and water jade has a resinous luster. B+C jade is close to a resin luster and shows more of an epoxy resin luster. For example, the luster of these jade bracelets today clearly has the luster of epoxy resin, and when you look through the light, you can see the slight purple color of the material inside, which shows that they are B+C jade. The light transmittance of jade is consistent with the color of the jade itself, and no other colors will appear.

Finally, shaking the jade with your hand and observing its surface is also a quick way to identify jade. The density of jade is relatively large, and it will feel heavy in the hand. If the jade is acid-washed and injected with glue, its weight will be reduced and it will be lighter in the hand. If you observe under magnified conditions, you will see acid-etched reticulation on the surface of B+C jadeite, and the green part will have no color roots.

In fact, the easiest way is to take it to the quality inspection station for re-inspection. If it is B+C jadeite, the quality inspection station will not issue a certificate. It will directly tell you that it is processed jadeite, and you don’t have to pay. If it is natural jade, the appraisal fee is only about 10 yuan. It is a good choice to buy it for peace of mind.
