The easiest way to identify jadeite, the easiest way to identify jadeite

The hardness of natural jadeite is high, so the surface of jadeite is not destructive when carved with a knife, but if you use a knife to carve the cushion color jadeite, the diaphragm on its surface is easy to fall off. The luster of artificial jadeite is relatively dull, its color appears dull and impure, there is no sense of layering, and there are cracks on the surface of the color. The sound of two artificial jade bracelets colliding is rather dull.

Fake jadeite contains small bubbles that are not easy to spot, so you need to use a magnifying glass to observe them. --Quoted from experience.

There are many ways to identify jadeite, but now there are endless counterfeiting methods on the market. Therefore, the buyer must have some basic jadeite common sense and be able to have the ability to distinguish the real from the fake. Some jadeite has been unearthed in Yunnan, China, but it cannot meet the needs of the domestic market, and most of it is imported from Myanmar.

You can use a rope to hang the jadeite in the air, and then knock the jadeite with your hand, the natural jadeite will have a crisp sound, and the artificial jadeite sound is more muffled, this method requires a long time of practice to appreciate the difference.

Natural jadeite does not undergo any in-house processing, but is only sanded and carved on the outside. True jadeite can see obvious color roots in the sun, the color roots from light to dark, the color will slowly fade, but you can still clearly see the direction of the veins. A large amount of pigment is injected into the jadeite on the market, which has caused damage to the internal structure of the jadeite, and some color roots can be seen, but the structure is disordered and complex and discontinuous.

There is also a simple and crude method. Put the jadeite on the fire and roast it, if it is not dyed black, it is **, but it will cause damage to the jadeite, do not use this method easily.

The easiest way to identify jadeite How to distinguish the authenticity of jadeite with a drop of water.

Here's how:

1. Look at the jadeite, which is the unique feature of natural jadeite, and the counterfeit products made of imitation glass and porcelain are not jadeite.

2. Listen to the sound, gently knock on the natural jadeite will make a louder and crisp and pleasant sound, and the counterfeit will make a very dull sound, but not all jadeite jewelry is applicable, and the bracelet is more suitable.

3. Weigh the weight, just weigh it in your hand, generally natural jadeite will have a feeling of pressure on the hand, giving people a heavy feeling, fake imitations such as water foam are relatively light.

Notes:

It is best not to put jadeite and other jewelry together, otherwise it may cause jadeite and other jewelry to wear and tear each other. When wearing jadeite jewelry, do not wear jadeite and other hardness jewelry in the same part, otherwise the jadeite may also be damaged due to bumps.

When wearing or preserving jadeite, it is necessary to pay attention to regular cleaning, because after long-term wear or storage, the surface of jadeite is easy to accumulate dust or other impurities. The jadeite can be sent to the jadeite shop for cleaning, or it can be gently brushed with a soft brush, or the jadeite can be wiped with a soft cloth dipped in a small amount of water.

The easiest way to identify jadeite is to look at the luster, internal structure, fluorescence reaction, and so on.

1. Look at the gloss.

Swing the jadeite left and right in the sun, carefully observe the luster of the jadeite surface, and identify the authenticity of the jadeite. Natural jadeite has a good vitreous luster, and the luster is not very strong. The jadeite after artificial dyeing and glue injection treatment has a strong resin luster.

2. Internal structure.

Observe the jadeite from the reflective surface of the jadeite under the sun, and look at the internal structure of the jadeite, the surface of the natural jadeite will appear with stars or flakes of flash, similar to the shape of a fly's wings and hail. In places where natural jadeite is not polished well, there is a high chance of fly wings.

3. Fluorescence reaction.

In a relatively dark environment, use a purple lamp to irradiate the jadeite to see if the jadeite has a fluorescent reaction. Generally speaking, natural jadeite has a better color under the irradiation of purple light and does not fluoresce. The artificial jadeite after artificial dyeing and glue injection will have a strong fluorescence reaction and appear blue-purple color.

Causes of jadeite formation:

1. It is believed that it is the desilicination product of the residual granite magma intruded into the ultramafic rock by magma under high pressure conditions.

2. It is believed that the primary albite is formed by the decomposition of jadeite during regional metamorphism, and it is believed that under the compressive torsional stress and low temperature caused by plate collision, albite first forms blueprint schist with a low degree of metamorphism, and further metamorphoses into jadeite.

3. It is believed that it is formed by metasomatization of granite and pale gabbro under the pressure of 12 14kPa and under the action of hot water solution with high chemical potential of sodium.

4. Opinion: According to the discovery of the water-bearing methane jadeite three-phase inclusions in jadeite rock, it is believed that jadeite is crystallized by a near-jadeite silicate melt, and it is believed that this melt originates from the alkali-bearing pyroxene layer widely existing in the mantle at 300 400 km.

The practical identification methods of jadeite are as follows:

1. Observe the color discrimination method.

Color is a very visually striking thing, so when we see jadeite at first glance, we usually focus on its color, and then we can carefully observe whether its color is pure and uniform. The purer the color, the more variegated the jadeite and the more natural the color transition, the better the quality will probably be.

2. Hand feel discrimination.

Generally speaking, the density of real jadeite is relatively large, so you will feel heavy when you get it in your hands, and there is a hint of coolness, which is very round and comfortable to the touch. But fake jadeite is different, they are usually relatively light, there is no sense of weight in the hand, and there is even a plastic feeling to the touch, so you can use your hands to weigh more.

3. Listen to the sound discrimination method.

There is an old way to identify jadeite, that is, gently tap the jadeite, and then listen carefully to whether the sound it makes is crisp and beautiful, the crisper the sound, the higher the probability that it is true, because the imitation of counterfeit jadeite is usually filled with gelatinous inside, and it is difficult to produce this natural crisp sound.

4. Look at the emerald discrimination method.

Jadeite has its own jadeite, this jadeite is relatively easy to observe, if it is a real jadeite, as long as you look closely you can find that there is a flash of light similar to a fly's wings on its surface. This feature is difficult to imitate, so the success rate of using this method will be relatively high.

Precautions for buying jadeite

1. Don't magnify the flaws too much.

Jadeite is a mineral aggregate formed after tens of millions of years, and the formation process is very long, so it is inevitable that it will be invaded by some impurities or other elements in the environment, and there will inevitably be some so-called defects inside, such as cotton dirty spots and so on. When buying jadeite, you should also pay attention to not magnifying these flaws too much, and have a certain inclusive mentality, but don't be too improvised, put the form flat, and like it.

2. Be assertive.

The jadeite market is a very deep circle, mixed people and mixed jade are the need to take more precautions, see the favorite jadeite in the heart to have a suitable **, do not listen to the people next to you chatter to affect their own judgment.

Jadeite can be identified by practical methods such as hot water soaking, touching texture, and burning the flames.

1. Soak the jadeite in hot water, the natural jadeite will not fade when soaked in 60 degrees hot water, if the color fades, it proves to be fake.

2. Take the jadeite in your hand, first ** the color of its surface, and then touch it with your hands, the natural jadeite feels smooth, and the pattern is very delicate, while the fake jadeite is rough to the touch, and the pattern is very messy.

3. Burn the jadeite with a flame, if the jadeite does not fade, then it proves that it is a natural jadeite, and if it fades, it proves that it is a fake jadeite.

Precautions for buying jadeite:

1. Buy with your own financial ability, especially for beginners, and rational consumption is very important.

2. Jadeite with unclean and impurities is generally not recommended to buy, because jadeite with an unclean foundation affects the appearance.

3. It is best to see the color of the jadeite in natural light, and avoid observing the inside of the jadeite under strong light.

4. The transparency of jadeite is called "water head" in the industry, and the water head is transparent, translucent or transparent, slightly transparent, opaque, and the higher the transparency of jadeite, the better the quality. Conversely, the lower the transparency, the worse the quality.
