Mr. Ma, I would like to ask for an appraisal of whether it is a jade A cargo, thank you!

Hello, follow your three questions.

Answer them one by one.

1. This is undoubtedly a cargo You can rest assured.

Under natural light, the orange peel effect of A goods is obvious, and there is no doubt that it is genuine.

The material is basically to the ice species.

2. The small pit is a reasonable existence for the normal A goods polishing pit.

When the finished product is produced, it will be waxed.

After wearing it for a while, it will sometimes appear.

But you won't have much of this kind of material, so don't worry.

3. In the case of no cracks, the price is still relatively acceptable.

If you have any questions, please continue to ask.

I hope to choose as satisfied Thank you.

There are many types of jade, including mixed species.

The ice species is okay, but it can't be said to be a goods, because jade is a thing, it is a person, and if you like it, it is a goods.

2300 is also reasonable, not too expensive.

The potholes can only be said that the manual is not good, not too good.

I am a senior salesperson working in Chow Tai Fook, and I don't know how to ask questions.

Hello, your jadeite does not have the properties of jadeite such as water head and jadeite.

It should be used with other substances, such as white stone, etc., to pretend to be a jadeite after injection, which does not contain jadeite ingredients, and is not jadeite B goods.

Because it is full of gelatin, it is prone to small pits.

There are too many fakes out there now, so you need to be cautious when buying.

What are the identification characteristics of jadeite A goods, the following is introduced from eight aspects: jadeite, natural color, strong luster, high hardness, high density, no abnormality on the surface, crisp sound, no abnormality in composition, and generally jadeite A goods can be basically identified from these eight aspects.

Jadeite A goods identification - jadeite, natural color, strong luster.

Emerald: When the jadeite grains are coarse, the jadeite is clearly visible to the naked eye, and when the grains are fine, the jadeite can only be seen with the help of a 10x magnifying glass. The jadeite with very fine grains of high-grade glass-bottomed jadeite must be magnified about 40 times with the help of a microscope to observe the jadeite.

Natural color: The color of natural jadeite spreads along the direction of the texture, the colored part and the colorless part are in a natural transition, the color shape has a beginning and a tail, and the color looks like it grows from its fibrous tissue or granular crystal (commonly known as colored root), calm but not empty. The green color does not change red under the Charles color filter and is gray-green.

Strong luster: the polished surface has a glass luster or sub-glass luster, the refractive index is high, and the high-grade jadeite is like a mess of autumn water, which is transparent and beautiful.

Identification of jadeite A goods - high hardness, high density, no abnormality on the surface.

High hardness: The hardness is higher than all other jade.

Denser: The density is suspended in diiodomethane.

No abnormality on the surface: under the gem microscope, the surface of most natural jadeite is "orange peel structure", when the grains or fibers of jadeite are coarse, although there are some rough uneven or concave patches on the surface, but the surface of the non-concave is smoother, and there is no reticulated structure and filling. There are also a small number of natural jadeite, due to geological stress and weathering, can produce obvious cracks and reticulated structure, observed under the microscope, and the cracks formed by acid corrosion are very similar, but such jadeite, there is no glue inside, with the help of a pull spectrometer or infrared light meter, can draw accurate conclusions.

Jadeite A goods identification - the sound is crisp and the composition is not abnormal.

The sound is crisp: Hit two pieces of jade and jade against each other, or hit the object to be measured with a jade piece, if it is a goods. It emits a crisp "steel sound", and if it is not a goods, the sound is dull, however.

Listening to the sound is only for reference, as if the craftsmanship is "superb" B goods, as well as most of the C goods, in the ordinary people's sound, its sound is almost no different from natural jadeite.

No anomalies in composition: The main chemical composition can be quickly and accurately determined with an electron probe

Sodium oxide (Na2O): about 13%;

Aluminium oxide (al-knife,): about 24%;

Silicon dioxide (Si02): about 59%.

1. There are several ways to identify a cargo jadeite: observe whether there are impurities. Since jadeite is formed in nature, if it is a cargo, there will inevitably be some impurities, such as black, yellow or gray body, while the treated B cargo, there are few impurities, because it is corroded by the strong acid silver.

Look at the color root. 2. A jadeite blisters do not reflect white light. A jadeite is pure natural jadeite, **, flashlight irradiation will not reflect white light. B Bracelets reflect white light and front oaks. B goods bracelet is the artificial processing of jadeite that has been cleaned and bleached, covered up cracks, injected with glue and polished.

3. You can also use the water drop method to identify the authenticity of a jadeite. The surface of a cargo jadeite contains oil, and after the water droplets drop on the top, the water droplets will be in the shape of dew and hail beads, which will not disperse quickly, while the fake A jadeite will quickly dissipate when it encounters water droplets.

To distinguish whether jadeite is a goods, the most rigorous and objective is to buy, be sure to bring a natural jadeite A certificate issued by an authoritative appraisal agency to buy, no certificate of jadeite, do not buy.

Daily identification: mainly look at the surface luster of jadeite jade. A goods gloss is generally strong glass luster. The luster of B goods is dull, generally looks waxy or resinous luster, the surface and shallow part are more transparent, and the further you go inside, the more cloudy it becomes. Illustration:

Hello, Mr. Ma is busy these days, and may not be able to see your question in time, so I will answer it on my behalf.

It can be checked.

This is a natural jadeite A goods bracelet, genuine.

The materials are less, no species and no color.

The appearance is plain and elegant, and the color is relatively average.

A goods are undoubted, the official website can be reviewed, and the national inspection qualification of the testing agency should be completely assured to wear it.

The identification of jadeite (a) goods by national appraisal institutions mainly includes the following items:

1. Shape 2, color quality 3, weight 4, specific gravity 5, photoculicity 6, refractive index 7, spectral characteristics 8, stone structure 8 must be inspected.

The spectral characteristics refer to the two absorption lines adjacent to 437nm in the near-infrared spectrum of jadeite. This is also the most authoritative jadeite feature, and others can be faked, but this is the only one that is difficult to break through.

The definition of jadeite by the state. On the basis of the composition analysis and physical property testing of a large number of jadeite samples in the market, jadeite is finally defined in accordance with the principles of science and operability

Jadeite or a mineral aggregate composed of jadeite and other sodium, soda-lime pyroxene (sodium chromium pyroxene, omphacite), which can contain small amounts of amphibole, feldspar, chromite and other minerals. Mill hardness, density, refractive index, point side.

As can be seen from the country's definition of jadeite; In fact, many of the stones are characterized by the proximity to jadeite. Such as albite. Chrome ore, jadeite, pyroxene, and many more.

When the structure or component ratio of a piece of "jadeite" deviates from the jadeite stone, some corresponding physical and chemical indicators will also change slightly. According to the country's definition of jadeite stone, it is not jadeite in the real sense, but it has most of the characteristics of jadeite, and it is still beautiful, many more beautiful than jadeite! Such as albite.

Merchants and manufacturers make unfavorable tests on their "jadeite" in order to avoid the national appraisal agency's mandatory inspection items for jadeite. As a result, some places have "copycat" testing institutions. According to the intentions of those merchants with ulterior motives, the "jadeite" that cannot pass the national appraisal agency", do a symbolic test, avoid the important and light, and omit the most important test items.

They are embarrassed to get their own benefits, taking advantage of the lack of professional knowledge of the majority of consumers, and deceiving consumers.

If you compare it, you should have the bottom of the play.

This jadeite pendant is also not good enough for gem quality, so it is not worth estimating. Just play around.

Natural jadeite A goods pendant.

The carved one is a leaf.

Glutinous species: The overall light oil is blue.

The quality of the water is very average.

The net price does not exceed 200

The general market transaction price is around 3-500.

Hope you didn't buy expensive.

If you have any questions, please continue to ask.

The jade jade market is deep, and it is not uncommon for tens of thousands of yuan of jadeite to be traded for hundreds of yuan, depending on the seller's mouth and the buyer's IQ.

The volume is small, and the visual inspection **** is about 2-300 yuan.

The three jadeite ornaments you provide, as you look at the piece, (excluding the beads with beads "may be 24k gold"), jadeite alone, ** will not be too high. It should be between 150-300 yuan.

The ** of jadeite is often evaluated in terms of pits, species, water, color, and carving. And the few jadeite ornaments you presented belong to the new pit glutinous species, and the water color is ordinary. Guanyin, Buddha, the bottom is clean, but there is no emerald color.

Although the safety buckle has a single emerald color, it is only implied by bean green. The carver belongs to the general goods of the big road goods. That is, regular engraving.

It does not belong to the category of exquisite carving.

In addition, the ** of jadeite is also related to the place of purchase. If these emerald pieces are purchased at the mall. Then the unit price can be bought for about 500 yuan.

Because the cost of the mall is large. The price is naturally high. If you buy it in the market and other places, then the unit price is about 150 yuan - 300 yuan.

In addition, it should be noted that the certificate identification you provide can prove that it is made of natural A goods. It is not directly related to **. All emerald signs are the same.

For example, a 10,000 yuan jade Guanyin, its point refractive index is and a 100 yuan jade Guanyin's point refractive index is also.

Natural jadeite A goods gold inlaid jade longevity lock pendant. Genuine and safe to wear!

Shopping malls are mostly sold at a discount, with a general texture of jadeite material in the middle of the place and then with a thin piece of gold to sell (generally a thousand feet of gold foil pressed into a gram of ** can be made into about square meters of pure gold foil paper, the thickness is.

In the case of no cracks, the actual price is within 300, and the jadeite part is generally planted with water, and the color is uniform.
