Myanmar jade jade true and false eye recognition
First, Burmese jade is also known as jade jade
It was once popular in the late Qing Dynasty and the early Republic of China: for example, a jadeite tube of the Minister of the Ministry of Internal Affairs of the Qing Dynasty, worth 13,000 gold. In the mid-1930s, Beijing Jade King Tie Yuting had a bracelet and sold it to Shanghai Du Yueyu for 40,000 silver dollars.
Due to the high hardness of the jade jade in Myanmar (also known as water species), it is bright and bright. And the good jade color is bright and peaceful, with high preservation and collection value, so it is called "the king of jade". It is loved by many people who love jade and jade. Japan and New Zealand also regard jade as the "national stone" of the country. Because jade jade is produced in the vicinity of China, and most of the finished products are processed in China, and the Chinese have a special preference for jade jade, Western countries generally believe that jade is China's “national jadeâ€.
Second, the color of Myanmar jade jade
The color of Myanmar jade jade is slightly different due to the different customs of the region. In the jade kingdom of Myanmar, the jadeite is divided into three categories and 12 levels. The domestic jewelry industry has subdivided it into more than 30 grades according to its different colors. The general tone of the color of the jade can be roughly divided into the following six.
1, white. It is basically free of other impurity elements. 
2, red. Containing the chemical element iron <Fc3+> <commonly known as 翡>. 
3. Green. Containing more than 2% of chromium <Cr> <commonly known as Cui>. 
4, black. Contains 2% or more of chromium <Cr> and iron <Fe2+>. 
5, yellow. Contains elemental é’½.
6, purple. Containing elemental chromium <Cr> iron <Fe>cobalt <Co>. 
In particular, the green color of Burmese jade, in addition to its bright color, very durable, it can be worn regardless of identity, status, age, gender. Therefore, it is in line with the Chinese's implicit, peaceful, gentle and intimate personality. The demand for society is rising. Prices have also doubled and even increased by a hundredfold. At present, the price of a green and green bracelet on the international market has reached more than 10 million yuan. Even the jade-colored jade jewelry, as long as it is a real A goods, water head, craftsmanship, color coordination, but also expensive.
Third, the market's Burmese jade products and simple identification
Regardless of the amount of minerals or the amount of mining in Burma, good jadeite is very limited. Therefore, some speculators and merchants who are profitable are “thinningâ€. A lot of fraud, fraud, and profit from it. Even in Myanmar in the Emerald Kingdom, fakes are always available. Fake stones and fake ornaments can be seen everywhere.
At present, the types of Burmese jade that are popular in the market are classified according to the true and false grades, and there are mainly the following four categories.
A goods, both natural texture and natural color. The identification method looks at the following three points. 
(1) Think twice and act with discretion. Due to the relationship between mineral deposits and mining volume and specific conditions for people's large demand. There are currently few good jade jade on the market. In particular, the colors are green and the variety of the ground is very small. 
(2) Generally, varieties such as sapling green, bok green, ochre or violet flower are common. 
(3) Under the light, the texture is fine, the color is soft, the stone pattern is obvious; the slight impact, the sound is crisp and sweet; the handcuff has a heavy feeling, which is obviously different from the rest of the stone.
B goods, there will be black spots commonly known as "dirty" jade, soaked and corroded with strong acid, remove the "dirty" and "cotton" to increase the transparency, and then use high pressure to penetrate the epoxy resin or substitute filler into the strong acid corrosion In the micro-crack, it acts to fill and consolidate the crack.
(1) B goods at the beginning of the color is good, carefully observed, the color hair hangs evil, observed under the lamp, the color transparency is weakened. 
(2) B goods gradually lose their luster in two years, and they are covered with cracks and become very ugly. This is caused by the destruction of the original quality by strong acid. 
(3) Density decreases and weight is reduced. A slight impact, the sound is boring, and the crisp sound of the A goods is lost.
C goods are completely artificially colored. 
(1) At first glance, the color is not correct and evil. 
(2) Under the lamp, the color does not exist naturally in the interior of the jadeite crystal, but is filled in the crack of the mineral, showing a network distribution without color roots. 
(3) Observed with a Charles filter, the green color turns red or colorless. 
(4) Scrubbing with strong fading, the surface color can be removed or turned brown.
D goods, D goods posing as jade jewelry mainly have the following two categories. 
(1) Jade class. That is, other jade is posing as jade. There are mainly Thai jade and Malaysian jade, Nanyang Dushan jade, Qinghai jade, dense jade and Australian green jade and Dongling stone. The difference between the above jade and the jade of Myanmar: one is low hardness, the other is low density (light weight), and the gloss is weak. 
(2) Green glass and green plastic. Most of these alternatives are ugly and the gloss is very weak. The relative density is very light, the hardness is low (the nail can be inscribed), and there is no cold feeling.
The above method is only a little experience and experience of the author. It is really necessary to identify with technology and advanced technology. Such as high magnification magnification observation, measurement density and thermal conductivity, infrared spectrum Raman test.
