Don’t mistake “real” jade for “A-grade” jade. Let me teach you how to identify it!

It is a genuine product and it also includes returns and exchanges. Most jade lovers think it is okay to go in and take a look. Then after going in, they find that the bracelets are of good quality and the price is not expensive, so they tend to spend what they think is a reasonable price to buy a jade bracelet. When they get home and identify it, they find it is a B-grade bracelet. Then you will run back and ask the seller, why did you sell me a B-grade bracelet? Didn’t you say it was 100% genuine?

Yes, it is the real thing, but it is not A-grade goods. These tricks really deceive people.

Even if you find out it’s a B-grade product, if it’s a not-too-expensive bracelet, you won’t spend so much time going back to return it for a return or exchange.

If it is an expensive bracelet, you will run back, but even if you run back it may not be of any use, because she said it is 100% authentic, she did not say it is 100% A grade, so there is a trap here, no matter it is B grade or B+C grade, they are made from jade, but it has been chemically treated, it is not other jade, it is just jade that has been artificially treated, its essence is still jade, so when people say it is real jade, they are not lying, these dealers are taking advantage of the loophole and playing a gray area.

It’s like when people sold palladium in the past, they would say it was platinum. This is not wrong. Platinum includes palladium, and platinum and K white can also be called platinum. Therefore, it is very important to understand jade A, B, C, and B+C goods. If one of our customers comes here today and takes a piece of jade, how do you prove that it is genuine jade?

Therefore, we have to use professional identification methods to convince him, so that he knows that you are professional in this area. People like to make friends with professionals. Who knows, your deal may be closed and it may also bring you customers. It is your expertise that makes you friends.

The so-called B-grade jade is low-grade jade that has been processed by artificial chemical and physical methods, such as strong acid rinsing and filling with glue, which can remove impurities, increase its transparency, and make the original color more beautiful.

What is the biggest difference between B-grade and A-grade products?

That is to say, the internal structure has changed, so what are the changes in the B goods? In fact, B-grade jade is also called processed jade, which means that some impurities and colors that affect the beauty of jade are removed, and the cracks are filled to increase transparency.

So how do you identify B-grade jadeite? This may sound a bit old-fashioned, but it bears repeating!

(1) Look at the network cracks

The low-hardness resin glue in the gaps between the mineral particles is polished to form a network of concave grooves and fine lines that surround each crystal particle.

(2) Glue-filled cracks

a. Under reflected light, the cracks can be seen through a microscope as a flat surface with weak gloss;

b. An open fissure that is very clear on the surface but not clearly extending into the interior.

(3) Glue filling pits

Because jade contains mineral components that are easily corroded by acid and alkali, such as chromite, mica, and albite, they are dissolved during the processing to form large voids. The voids are filled with a large amount of resin glue, forming pits during the polishing process.

(4) Clean background

When viewed through a window or fluorescent light, the white part of B-grade jadeite does not have any gray or yellow color, and the green part appears particularly bright and pure.

(5) Relative density

The relative density of B-grade jadeite is generally smaller than that of natural jadeite, and it floats in diiodomethane molten heavy liquid. Some natural jade will also float in the 3.32 heavy liquid and feel light.

(6) Ultraviolet fluorescence

B-grade jadeite has a weak to strong bluish-white fluorescence.

(7) Tapping

After being filled with glue, the spaces between the mineral particles of jadeite are filled with glue, and it makes a dull sound when tapped lightly. Of course, as counterfeiting methods become more sophisticated, this method is no longer applicable!

(8) The surface reflection is not clear

(9) Infrared spectral characteristics

a. Hydrocarbon peak: absorption peaks at 2870, 2928 and 2964 wavenumbers, among which the absorption at 2964 wavenumber is stronger than that at 2928 wavenumber.

b. Alkenyl peak: absorption peaks at 3035 and 3058.

c. Finger-shaped peak: When there is more resin glue in B-grade jadeite, in this case, the peak system composed of 4 absorption peaks at 2430, 2485, 2540 and 2590 wave numbers becomes more obvious, like a finger shape.

Types of B goods on the market:

Bean-type high emerald green color glue-injected jadeite: Bean-type high emerald green color glue-injected jadeite means that the color is real, but it is injected with glue to improve its transparency and clarity. This kind of B-grade jade with high emerald color and injected glue is currently called high B-grade jade in the market.

Then many jade lovers will ask, why does emerald green jade need to be injected with glue? Originally it was a bean-type jadeite, but the base color was grayish and impurities had penetrated into it, so the emerald green color could no longer be seen. The glue injection treatment can improve its transparency and clarity, allowing its emerald green color to be well displayed.

How to identify it?

①A-grade jadeite will more or less contain some impurities and rust; however, this high-quality B-grade jadeite is very clean and does not contain these impurities and rust.

②The color of A-grade jadeite is concentrated; while the color of high-quality B-grade jadeite is diffuse, brighter and more transparent.

③The color of A-grade jadeite is uneven, the white areas are white; while the white areas of this high-quality B-grade jadeite cannot be made white and appear more transparent.

④The transparency of A-grade jade is uneven, the green part is more transparent, the white part is whiter, and it appears to have more cotton wool; while the transparency of high-quality B-grade jade is uniform everywhere, the transparency of green and white is consistent, and the white part is not white, and appears very transparent.

Many jade lovers have not had much contact with jade, so it is still difficult to understand these identification methods. San Ge will teach you the simplest method. Find a jade merchant with a good reputation, pay attention to the product photos he posts on the Internet or in the circle of friends, and look at them every day. It won’t take much time, and your eyes will be able to intuitively judge the authenticity of the jade!
