What are the main reasons for the formation of emerald? Jade is How's that? There are many magical folk legend; geologist've been referring to it as a mystery, it has been considered as emerald and diamond, are deep in the crust several thousand degree heat and high pressure conditions, crystal formation, it is not true; the United States many Geophysicists have done a lot of simulation experiments in the laboratory, combined with jade deposits found around the world, the actual situation, they believe that jade is not formed under high temperature conditions, but in the middle ─ pressure at very high temperature conditions Deteriorating causes.
The Government of Myanmar jade auction held every year, attracted many buyers. Tohoku University, Professor Ichiro Sunagawa, "saying the stones" (1983) was published a book, more specifically pointed out that the jade was 10 000 at atmospheric pressure and low temperature (200 - 300oC) formed. We know from the surface to the deep Earth, The depth of the more higher the temperature, the greater the pressure. But Jade is under high pressure at low temperature crystallization, of course, impossible in the deeper part, then the pressure really come from? This pressure is due to crustal movements caused by the formation of extrusion pressure, has now been confirmed that the distribution where there are emerald deposits in the region, are more intense crustal movement zone.
There is another factor: the formation of any place where jade found both sodium feldspar igneous intrusion (in ─ basic rock). The chemical composition of albite as NaAlSi3O8, so you can guess ─ Jade is in the low temperature and high pressure conditions, sodium feldspar from the silicon to the role of the rock formed. Jade is customary, also known as Myanmar jade, jadeite produced in Burma, Japan, the Soviet Union, Mexico, California, Deng Jun births jadeite, but quality and output is far less than Myanmar. Area north of Myitkyina in Myanmar, the largest jade deposits in reserves, have long emerald gem mining, the supply of the world.
So people a long time before Burma produced only know jade, jadeite therefore as a synonym for Myanmar jade, and jadeite is the scientific name, and the Burmese jade is the expert jargon. Habits, also known as Burma Jade Jade is jadeite produced in Burma, Japan, the Soviet Union, Mexico, California, Deng Jun births jadeite, but quality and output is far less than Myanmar. Area north of Myitkyina in Myanmar, the largest jade deposits in reserves, have long emerald gem mining, the supply of the world.

How to distinguish white jade and white
White jade on the market, adding more water to mix. Some operators will not be called white jade white jade white jade, the objective of misleading the consumer.
In China gemstone wholesaler , white is jade a particular species is the specific name of the white nephrite. Nephrite because produced in Hotan, Yutian, etc., so often referred to as Hetian, in nephrite. Nephrite containing mineral and chemical composition due to differences lead to different colors, so there nephrite jade, jade of points, there are jasper, black jade and so named because of the soft jade color varieties.
The main mineral nephrite tremolite and actinolite, the ratio between the two levels vary widely, followed by even a small amount of other minerals, when the soft jade in the tremolite content of more than 95%, because of tremolite low in iron white, this white is white nephrite, jade is a high-grade jade, which like to Make suet are known as "mutton fat jade" is very expensive nephrite variety. Their precious white jade very popular.
In short, white jade, white jade is mainly tremolite; dominated by the formation of other mineral jade, white and must not be known for its white color. Why, then, will happen "at will" named "white" mean? There are two reasons, first, some operators do not know the composition of white jade refers specifically tremolite nephrite, but according to the color name; the other, deliberately not referred to as white jade, white jade, or impurities, which is a wrongful act.
In the jade market, often referred to as two white jade white jade.
First, quartzite class jade, white color, smaller, look like white jade, the last so-called "Beijing jade" is a fine-grained quartzite, Department of china jewelry Geology and Mineral Evaluation of the "whetstone" mine, very fine particles, but can not say the white jade, jade quartzite class than the white high hardness, therefore showing more white shiny glass, in the absence of case detection equipment can thus differentiate.
Second, jade calcite type, appearance similar to white, case of the market on the so-called "Afghan White Jade" is formed by the calcite, jade, in fact, a kind of marble, but color is white, translucent, often carved cabbage, moral symbols " 100 Assets. " This jade hardness is very low, ordinary knife that can be engraved action, is not difficult to recognize.
Of particular note is that some second-hand market, often posing as white or jade glass, glass to see the size of uncertainty in the usual Youyi round bubble. As long as you can see a bubble is definitely not white. However, some glass and no air bubbles, so no bubbles are not necessarily real. To be sure to buy the real thing, or should we look for the detection of jade china jewelry wholesale department to detect, because some white jade resembles white, not to rigorously test, it is difficult to make accurate judgments.
