1. At present, the jade market price is about 600 ~ 1000 yuan, which is the normal selling price, and generally does not exceed 1000 yuan.

2. Grams. At present, the jade market price ranges from 100 to 150 yuan, which is quite common in the jade market.

3. Hello! A new jadeite (A) bracelet, with a granular and fibrous interwoven structure, costs 4000 ~ 5000 yuan.

4, glutinous jade bracelet, the foundation is relatively delicate, look at the weight bar, there is no crack as small as 1,000 yuan.

Green, fiber columnar interwoven structure, refractive index 1.66, absorption spectrum: jadeite characteristic spectrum!

The seeds are tender, cotton is abundant, the water head is general, the color is light and tends to be flat. Carver standard, but not brilliant, the size is not too big. The whole jade pendant belongs to the middle and low grade. At present, the jade market is 96 grams, and the normal price is around 400 ~ 600 yuan.

The seeds are tender, rich in cotton, with average water head, light color and rough carving. The advantages are solid materials, regular shape and large size, and it belongs to the middle and low-grade practical wearable pendant. 3 1 1 At present, the market price of jadeite is about 600 ~ 1000 yuan, which is the normal selling price and generally will not exceed 1000 yuan.

Color: refers to the color of jade. Of all the colors of jadeite, green has the highest value. And the change of color, we call it "three colors", and red represents blessing; Green means money is wealth; White represents longevity.

This is the Emerald A bracelet, the texture is a little poor, and the water plants are also a little poor. If it is not cracked, the value is about 1000.

The structure of columnar particles and fibers is a special structure of jadeite, which means that the interior of jadeite is made up of many columnar particles, granular crystals and fibrous filaments intertwined and densely piled up under the polarization microscope. Generally, the finer the jadeite, the more delicate it is, and the less visible it is.

The number of this experiment is: the identification certificate of jadeite (A) flower.

Jade bracelet A goods 5 1.03g, fiber interwoven structure to granular fiber structure, refractive index 1.66, full. ...

1. The newly bought bracelet was tested by Guangdong Gold, Silver and Jewellery Testing Center, and the certificate can be found online. Among them, the total mass is 60.0 1g, the refractive index is 66 (spot measurement), the optical characteristics are heterogeneous aggregates, and the enlarged inspection shows the granular fiber interwoven structure. Note: infrared detection shows the characteristic absorption peak. Appraisal result: Jade (a). The salesman said it was made in Myanmar.

2. There are usually three kinds of jadeite inspection results: columnar granular fiber structure, granular fiber structure and fiber interwoven structure. The crystal of jadeite is the coarsest in columnar particles, followed by granular particles, and the fiber interwoven structure is the most delicate, which is a necessary item to observe the physical composition and structure of jadeite.

3. The refractive index of jadeite is about 66, while the refractive index of green nephrite that looks like jadeite is 6 1~63, and the refractive index of timely jadeite that pretends to be jadeite is 54. So as to distinguish the species with different refractive index from jadeite.

4. Compared with jadeite, there is no problem in describing density and refractive index. If there is nothing wrong with your certificate and it matches the bracelet, then it can be judged to be true. But if anything goes wrong in any of the above links, it's hard to say. It is recommended to provide the natural light map of the window in kind, which is safer with the certificate.

Emerald certificate number is ha11120804697, total weight is 63. 1g, refractive index is 1.66 (spot measurement), and density is 3.33gcm3. ...

1, jade density 33, refractive index 66 is the meaning of a piece of jade. The density of jadeite is generally between 30 and 36 grams per cubic centimeter, and most jadeite is about 33 grams per cubic centimeter, so the general appraisal certificate will write 33. If it is less than 33, it proves that it contains more impurities.

2. The material and water head of Jade A goods are generally lower than the average level, which has no value and collection value. Below 300 yuan, it is not worth buying more. Haven't you heard a word? If it doesn't open for half a year, it will open for half a year. It's a jewelry store.

3. The serial number of this experiment is: Jade (a) bracelet identification certificate.

4, dear, this is the Jade A bracelet, the texture is ok, it is exquisite, the head is good, and the value can be around 6000.

Emerald pendant, refractive index 1.66, total mass of 8.07g, granular fibrous interwoven structure, is it A? price

1, waxy jade with dark green floating flowers on white background, is A goods. It belongs to common low-grade jadeite. About 300 to 500 is suitable.

2. For the time being, the value can only be calculated at the price of 4 grams of pure gold. Although that piece of jade is A-quality, but the enlarged inspection structure is granular fiber, it is estimated that the quality of jade is not high-grade. The price of jadeite has a lot to do with its water sculptor. The parameters are different, the prices are very different, and there is no picture, so it is impossible to judge.

3. Jade pendant with waxy background, the foundation is ok, the carver is rough, the size is not large, and there are no cracks of about three figures.

What does the refractive index 1.66 (spot measurement) of the jade bracelet represent?

1, the refractive index of jadeite is about 66, while the refractive index of green nephrite that looks like jadeite is 6 1~63, and the refractive index of timely jadeite that impersonates jadeite is 54. So as to distinguish the species with different refractive index from jadeite.

2. Jade, whether bracelets, pendants or beads, as long as it is made of jade, has a refractive index of 66, which is the physical characteristic of jade.

3. The refractive index of jadeite is about 66, while the refractive index of green nephrite that looks like jadeite is 6 1~63, and the refractive index of timely jadeite that pretends to be jadeite is 54. So as to distinguish the species with different refractive index from jadeite. Under normal circumstances, jadeite will be marked with refractive index as long as it carries a formal certificate.

4. The refractive index of jadeite 66 represents that jadeite is genuine. Refractive index is an important factor to identify the quality of jadeite. The refractive index of jadeite is the ratio of the propagation speed of light in air to that in jadeite.

5. The refractive index of jadeite is between 650 and 670. Most jadeite after bleaching and filling have a slightly lower refractive index. The refractive index is about 1.65 (spot measurement).
