Ms. Zhang of Xuanwei City, Yunnan Province, has recently suffered a lot of losses,
She wanted to identify whether the jade bracelet that had been handed down from the ancestors was true or false.
Because I don't understand the knowledge of jadeite jade,
She just heard people say you could wrap a hair around it.
The burning hair was real, so she did it, and the result...
The good emeralds burned out very obvious traces,
Later, experts identified this as a fine a-goods jade bracelet,
After such a burn, most of the water inside is taken away, and the loss is estimated to be millions!
Ms. Zhang cried and fainted after hearing this...
Fang Damin, director of the gold and silver jewelry inspection department of the Harbin Quality Inspection Institute, said that this method has been circulating in the folk for a long time, but it is too unreliable, which is actually the principle of heat transfer. However, when the fire burns the hair to a certain ignition point, the hair will also burn out. And in addition to jade, as long as the surface is smooth and the hair is tied tightly, many materials can make the hair burn continuously, like glass products, stainless steel products and so on.
There are many ways to identify the authenticity of jadeite, many of which can only be used as a reference, and the best way is to identify with an authoritative professional organization.
The following will tell you about the method of identifying the authenticity of jadeite without instruments, for reference only!
This is identified by the color gloss of the surface.
The color of natural jadeite looks very natural, whether it is green or red jade, yellow jade...
The colors are very evenly distributed, if you see the appearance seems to be bright and spicy, most of them are artificial dyeing, such as scorpion color. The so-called scorpion color is the method of artificial heating and heating, so that its internal limonite loses water and turns into hematite, so that the jadeite turns red.
Identified by weight.
Because the density of jadeite itself will be relatively large, we can put jadeite in the hand up and down a few times, feel that there will be a heavy downward pressure feeling, there may be real jadeite.
When the fake jadeite is in the hand, it will be a feeling of light fluttering, and there is no feeling of downward pressure.
Identification by hardness.
Jadeite is very hard. The hardness of jadeite is unmatched by other jadeite types and glass. Jadeite can be scratched glass, and it is doubtful if it cannot be scratched
Identified by tapping sounds.
Gently tapping the natural jadeite, it emits a crisp and pleasant "steel" sound, and if it is an artificial treatment, it emits a low and muffled sound;
There is a judgment of whether there is green or not.
Some expert monographs believe that the important feature of natural jadeite that distinguishes it from other jadeite (wrapped jadeite b goods) is that natural jadeite has "green" (commonly known as "fly wings"), that is, the crystal flash phenomenon within jadeite, which is the flash of mineral crystal surfaces. Microscopic jadeite generally cannot see "jadeite", so "jadeite" cannot be used as a characteristic sign of natural jadeite.
Identification is by soaking in hot water.
We can put the jadeite in boiling hot water, and after a while to see if there is any discoloration in the water, or rub the jadeite with a cloth to see if there is any color that falls, if it is real jadeite, it will not fall off the color.
Some dyed fake jadeite will soak the fuel after soaking in hot water, and there will be a significant discoloration phenomenon.
Use a magnifying glass to view its tangentials.
For some jadeite with incisions, you can use a high-powered magnifying glass to view the incisions, and there will be obvious irregular breaks on the real jadeite cut surface, and you can also see the delicate structure inside.
When you look at the fake jadeite cut surface with high magnification, the incision is still shiny and bright, which is obviously a fake jadeite that has been artificially processed.
Some of the following dizzying jadeite terms, let's take a look at it, maybe when to use it!
1. Price
We often hear terms such as "this price is in the small five", "this value is six", similar to the small three, the fourth, the fifth of these terms represent what does it mean?
First of all, the third, fourth, and fifth represent a price range, not a specific value. The small, medium and large represent the beginning of the price number 1-3, 4-6, 7-9, and the following three, four, and five represent the number of digits of the price. In this way, we can quickly know that the third grade is 100-399, the fourth grade is 4000-6999, and the fifth is 7000-7999. If you think a certain item is only worth about 800 yuan, you can say "this price is in the third year".
2. What is Cuigen?
On an all-green emerald ornament, see a little or a thin strip of slightly darker green, and this slightly darker green is a gradient transition to a relatively lighter green inner color root.
3. What is Jade?
Also known as fly wings, it is a phenomenon peculiar to jadeite. Jadeite is formed due to the fact that the jadeite crystals that make up jadeite have two sets of complete cleavage. When jadeite ruptures under external force, the fracture surface and adjacent grains rupture along the cleavage under strong mechanical stress to form a cleavage surface.
4. Head
The head of water refers to the degree of transparency of the emerald. It is often described as long, short, good and poor. The head of the water is long and the head foot is highly transparent, and the head of the water is short and the difference between the head of the water is low. There is also a saying that there is a fraction of water, divided into one point of water, two points of water, three points of water, when the light hits the surface of the emerald, the depth that can enter the interior can be divided into: 3.3mm depth for one point of water, 6.6 mm of depth for two points of water, 9.9 mm depth of three points of water.
5. Dry
Refers to the poor transparency of jadeite, generally coarser grain jadeite, is the opposite of water and water head good.
6. Species
Species are also called "seed fractions". This is a vague concept, and the names are various. For example, according to the transparency division of "high transparency, then good seed", on the contrary, the difference between the species; the transparency is called "old pit species", poor transparency is called "new species", transparency between the two is called "new and old species"; there are also "glass species" (transparency is very good), "ice species" (better transparency) and other names. According to the type of deposit, there are "old pit species" (that is, seed material) and "new pit species" (that is, mountain material). According to the quality of color and transparency, there are "flower blue seeds", "oil green seeds", and so on.
7. What is Eight Three Jade?
"Eight Three Jade" is a new jade species first discovered in 1983 in an unnamed mine in Myanmar. A few years ago, due to people's lack of understanding of it, the name of this jade species in China is quite confusing, it is not sold in papers or news reports, known as "climbing jade" (or "climbing stone"), "Bashan jade", "eight three flowers blue" or "eight three kinds", by the late 1990s, it has been called "eight three jade" in China's precious jade industry.
8. Sheet color

12. Out of the water
It is the last process of jadeite polishing, that is, the process of final polishing. It is often polished with a cowhide belt to polish the jadeite, and she appears smooth and shiny
13. Will emerald green be long?
Some people who wear jadeite will find that after a period of time, the green or green root of the emerald has spread, and the color is more uniform and vivid. This is due to the activation and migration of color-producing elements inside the emerald due to body temperature and body fluids. Generally speaking, the degree of change is related to the quality of jadeite and the health of the wearer.
14. Why does the contestant have to knock on the bracelet?
This is an easy way to check whether the bracelet has cracks and identify the jadeite b goods, the sound is crisp and pleasant for the perfect a goods, and the dull sound is b goods or cracks.
15. Is good jade cold?
To be precise, it should be good jade with good thermal conductivity, placed in a cool place with glass, which cool hand which is jade, placed in the sun, which hot hand which is jade.
16. Buy jadeite to choose color or water?
There is a saying that "look at the water first, then look at the color". Specific to each person should be according to their own preferences. Emeralds with good water color are rare and the price is staggering.
17. Is jadeite only produced in Myanmar?
