How can a novice distinguish the difference between ABC jadeite

In fact, many people have a misunderstanding about jadeite ABC goods, thinking that it is a grade division.

In fact, jadeite ABC is not a classification of grades.

It is a classification of

A-grade jade refers to pure natural jade that has not been processed by humans. We call it A-grade jade.

B-grade jade refers to jade that has been acid-washed, bleached, and filled, which we call B-grade jade.

C goods: refers to the jadeite that has been dyed, which we call C goods.

Jadeite ABC goods are a common type classification in the market, so many people are concerned about how to detect and identify them.

In terms of jade appearance, the biggest feature of B-grade and C-grade jade is that its colors are overly bright. Especially the B plus C products, which have been filled and dyed. This type of jade has a very beautiful appearance.

Because counterfeiting must focus on the appearance, which must be beautified as much as possible, the colors, especially those of C goods, are relatively bright. However, B-grade jade has a characteristic that because it has undergone two processing methods, acid washing and filling, the structure of the jade will change greatly. When we select B-grade goods, the overall gloss will be obviously affected. The A-grade jadeite is generally called glassy luster.

Because B-grade jade is filled with colloids such as epoxy resin, its luster is relatively dull, and it will show an oily or waxy luster. The above are some rough ways to distinguish it by appearance.

As for professional identification, there are many methods. For example, when we detect, we will use infrared spectroscopy to analyze whether the jade contains gum. If it contains gum-like substances, it is definitely a B-grade jadeite that has been artificially processed.

Of course, there are many other identification methods, such as the density of jade. The density of processed jade is relatively low, while natural jade feels relatively heavy in the hand.

From the perspective of identification. It is not a simple process to observe A, B and C grade jade with the naked eye, so when conditions permit, you should seek the help of a professional testing agency for testing, which will be more authoritative.

The most typical B+C products on the market are those that everyone thinks are too fake, but there are a lot of them on the market now. There are indeed many people who have been deceived by selling this kind of jade under the banner of old jade from Ming and Qing dynasties. This has happened many times in our daily testing process. It is easy for many jade novices to be deceived.

I posted three pictures above. They are all ring faces. It is relatively difficult to identify jadeite ring faces, especially with the naked eye.

This ring face is relatively large. You can pay attention to the picture. Of course, the picture may not be that clear, but you can get a rough idea of ​​it through the luster in the picture.

The first two pictures taken separately are both natural jadeite, which have not been artificially processed. The third picture, which shows two jadeite together, shows that both jadeite have been processed. This is what we often call B plus C goods processing.

Just from the appearance point of view. The difference may not be big, but if you look closely and compare them side by side, the luster of the processed jade will be slightly weaker. You can find a certain feeling through constant comparison and practice.

If you encounter this kind of translucency, and the base of the jade has this kind of blue, green, or purple hue, you must be careful, as it is likely filled. This requires further understanding by everyone.

For B-grade jade, there is another way to detect it: a major characteristic of B-grade jade is that the structure of the jade is destroyed. After the structure is destroyed, there will be no obvious granularity inside the jade, because the structure of jade is a kind of structure that we call square crystal. There are a lot of particles in it.

Once treated with acid washing and filling, the particles inside the jade are destroyed, and then filled with colloidal substances. The gaps between the jade particles are also blurred. Therefore, there is no sense of grain when we look through the B-grade jade.

These two pictures are translucent pictures. From these pictures, we can clearly see that the structure of B-grade jade is very fuzzy, just like the so-called paste-like feeling. There is no obvious grainy texture.

Also pay attention to the first picture. Let me remind you that we need to see what color the light that comes out is. The light that comes out is blue-white. For natural jade, because the crystal particles are very dense, the light emitted when transmitted is warmer, generally a yellow or light yellow color. As for B-grade or processed jade, since it is filled with gelatinous substances, the refraction of light is different, and the light that comes out is cooler in color, generally bluish, purple or green.

Please note that I am not referring to its background color, but the light that comes through. So when you are observing, you should pay attention to the color of the light that comes through.

C goods are relatively simpler. From the perspective of identification, we observe with the naked eye, with the help of a magnifying glass, or directly with the naked eye. You can see that its color is distributed in a spider web-like pattern along the gaps between the particles, giving a spider web-like feel. This is a typical feature of dyeing. Another feature is that, as I told you, its color is very bright. Even too gaudy.

In fact, when it comes to testing this kind of jewelry, it is not a simple concept that can be explained to everyone and then mastered immediately. This still needs to be based on more watching and observation. In some specific cases, special instruments are also needed.

Of course, for testing, the most essential thing everyone needs is a magnifying glass. This kind of handheld ten-fold magnifying glass is often used when we do identification. So if you are interested in jewelry testing, you can prepare a ten-fold magnifying glass yourself.

For situations like the one I just mentioned, it would be relatively easier to observe under a ten-fold magnifying glass. As I just said, B-grade jade has another characteristic, which is called surface acid etching reticulation. From the perspective of identification, this is also an indicative identification of B-grade goods.

This category refers to the fact that because the jade is pickled, some grooves will be left on the surface, densely distributed on the surface. For this kind of jade, we can also use a magnifying glass to observe whether it is A grade or B grade. Generally speaking, such grooves will not appear on natural jade.

Natural jade may feel bumpy, but it does not have this kind of groove feeling.
