How to identify the authenticity of jade: If you use these 4 methods, you will be wrong

"Jade from the Ming and Qing Dynasties" can be said to be one of the biggest scams in the jade industry. In 2013, there was a scam that old jadeite from the Ming and Qing dynasties could not be identified as A-grade jadeite. At that time, some dyed jadeite and green glass appeared in the market under the guise of "old jadeite from the Ming and Qing dynasties". These counterfeit products were sold at high prices.

In 2015, someone spent 600,000 yuan to buy this so-called "old jade from Ming and Qing Dynasties", but it faded soon after. This attracted social attention, and gradually the "old jade from Ming and Qing Dynasties" faded from people's sight.

Now the question is, how to identify it?

Speaking of this, those jade friends who like jade but don’t know how to appreciate it are in tears. Today, we will introduce 8 super practical identification methods.

Share it with everyone.

"Look first, touch second, weigh third"

1. Eyes are the windows to the soul. As long as you have a pair of discerning eyes, you can see 90% of jadeite!

①, Look at the "fly wings" of jadeite:

"Fly wings" are the small shiny surfaces seen on the surface of jade under the sunlight, like small wing-shaped shiny particles. This is a unique characteristic of jade, and the size of the shiny surface is related to the size of the jade particles. For example: it is easier to see "fly wings" in bean-type jadeite, but you cannot see "fly wings" in glass-type jadeite, because the particles of glass-type jadeite are very fine and no small shiny faces can be seen on the surface. Therefore, a large number of "fly wings" can be seen on the cut surface of rough jade, but they are not easy to see on the polished surface.

"Fly wings" is one of the important signs for identifying A-grade jadeite, but it is not the only sign.

②, Look at the "orange peel effect" of jadeite:

The "orange peel effect" is that when A-grade jade is observed through reflection on the polished surface, it will have surface features similar to those of orange peel with bumps and depressions of different sizes and directions. The "orange peel effect" is only prominent in A-grade jadeite, and the boundary between the ridges and troughs gradually transitions smoothly; the ridges and troughs in B-grade jadeite do not transition smoothly, but are separated by a crack, like a spider web-like crack pattern, which is called "acid etching network pattern", which is obviously different from the "orange peel effect".

③. Look at the glossiness of jadeite:

The identification characteristic of natural A-grade jade is that it has a distinct glass luster, which is like the reflection of the surface of glass. The luster is very bright, which is particularly prominent in high-grade jade. However, in some inferior jade, it manifests as a waxy luster.

④. Look at the color of the jadeite:

There are many colors of jade, the most valuable of which is green jade, also called "emerald green". As a result, various artificially colored jades are flooding the market. The color of jade is natural, moist and translucent; while dyed jade lacks luster, giving people a "dry" or "lack of water" feeling. Although the surface of the coated jade is also very smooth, it does not have the orange peel effect and has a sticky feeling.

2. Touch: Humans have highly developed touch nerves and can perceive a lot of information

Jade conducts and dissipates heat quickly, and will feel cool for a short period of time when placed on the face or on the back of the hand. Jade has high hardness and a dense and delicate structure. After polishing, it can have a very high surface finish and feels noticeably slippery to the touch.

3. Weigh: If you know the weight, you will feel the pressure of jade!

The density of jadeite is 3.34 g/cubic centimeter, which is higher than similar nephrite, Dushan jade, Xiuyan jade, Australian jade, Malayan jade (dyed quartzite), hard sodium jade and grape jade. But it is lower than Qinghai jadeite (grossular garnet), Tessawo stone (hydrogrossular garnet), etc. Therefore, if you weigh an A-grade jadeite in your hand and feel it hits your hand, congratulations, it is an A-grade jadeite!

4. Speaking of this, I can't help but think of a density measurement method.

We all know that the density of jade is 3.33g/cm^3. Today, Consultant Zhao has specially brought an identification method for jade fans. Due to the lack of more professional instruments, we can just use folk science. The advantage is that it is more down-to-earth, and jade lovers can identify it by themselves at home.

Prepare the materials:

1. A balance scale (with a minimum accuracy of 0.01),

2. An open beaker (a plastic cup is used instead due to the poor conditions), a thin rope,

3. Distilled water,

4. Grade A jade bracelets, Grade B and Grade B+C jade bracelets, and several flower pieces. (PS: There are plenty of Grade A jades available to Consultant Zhao, but it was difficult for him to find Grade B bracelets. In the end, he borrowed a pair of Grade B jades that were handed down from his ancestors to conduct the experiment.)
