It's obvious that the certificate is fake! The easiest way to identify jadeite

Whenever we talk about buying jadeite, Teng Pu Pavilion always reminds everyone to "carefully distinguish the real from the fake"! In the eyes of my friends, I am an expert on jadeite raw stones. I can tell the authenticity of jadeite at a glance. These are the experience and skills accumulated over more than 20 years. I will share them with everyone in Teng Pu Pavilion regularly, so that everyone can quickly and truly understand the jadeite raw stones, avoid detours, and let friends who like jade have a correct understanding when purchasing jadeite products, and don't be deceived and waste money! This is also the original intention of our Tengpu Pavilion!

Every time when talking about buying jadeite, Teng Puge always reminds everyone to "carefully distinguish the real from the fake"! But for most laymen, even if they have looked at the jadeite dozens of times, they still can't find any problems. What can they do? In fact, it is enough for most jade enthusiasts to understand the following knowledge about jade!

1. What is genuine jade?

Generally speaking, what we call genuine jade is Grade A jade, which is pure natural jade that has only been carved and polished without any chemical treatment, and has not been artificially falsified by high heat or high pressure. The color has not been dyed or electroplated. It is called "genuine color" or "real color." Depending on the degree of jade processing, jade can be divided into A-grade jade, B-grade jade, C-grade jade and B+C-grade jade. Grade A jadeite refers to natural jadeite that has not been artificially processed, while grade B jadeite is jadeite that has undergone a certain degree of optimization treatment such as bleaching and glue filling, and grade C jadeite is jadeite that has been artificially dyed.

2. How to identify the authenticity of jadeite?

First of all, we need to look at the texture. Many fake jades are acid-washed, which will have a significant impact on the surface and interior of the jade. After B-grade jade is rinsed with hydrochloric acid, there will be some uneven pits and a network of patterns on the surface of the jade, which are also called tortoise cracks. With the help of scientific instruments, it can be found that the internal structure of acid-washed jade is very loose. The surface of A-grade jadeite products will be uneven, which is known in the industry as the "orange peel effect." The coarser the jadeite mineral particles, the more obvious the orange peel effect will be. Cracking and orange peel patterns are important methods for identifying the authenticity of jadeite.

Looking at the color of jadeite, it is rare for natural jadeite to have uniform color distribution. Usually the distribution is uneven and the color depth is also inconsistent. The dyed jade is uniform and even in order to cater to people's pursuit of color, some merchants dye it into "full green jade". Artificially dyed jade has its internal structure destroyed, so the color accumulates and settles in the gaps, and the boundaries are blurred and diffuse, without the natural transition like natural jade.

Then you can also use instruments to identify it. Under the Charles filter, some dyed green jadeite will turn red; under ultraviolet light, some dyed red jadeite will emit yellow-green or orange-red fluorescence. Natural jade has no fluorescence under ultraviolet light.

Of course, these methods of identifying natural jade and artificial jade are not necessarily applicable to all jade, and should be used flexibly during the identification process. When purchasing jadeite, asking the seller to issue a formal invoice and appraisal certificate is also one of the ways we can avoid being cheated. In addition, based on many years of experience in the jade industry, we have summarized a complete set of effective jade identification methods. Comments and exchanges are welcome.
