Jadeite origin
Myanmar material, dangerous material and Russian material
One, origin
Jadeite formation conditions are very harsh. To be in the low temperature and high pressure, by the continental and oceanic plate movement under the tens of millions of years to form
become. Therefore, so far, only in Burma, Guatemala, Russia, Kazakhstan, Japan, the United States six countries have found. Currently, 95% of the world's commercial-grade jadeite comes from Myanmar, and 5% from the rest of the world. Next, let's take a look at the differences between the different origins of jadeite.
Two, Burma
Burma produced jade, superior texture, green color, comparable to the beauty of emerald, is the world's only high-quality jadeite jadeite country, so jadeite is also called Burma jade. We usually say that the jade is mainly pointed out from the Myanmar jade.
Three, Guatemala
Because in recent years, Myanmar's emerald resources more and more tight, Myanmar emerald prices continue to rise, Guatemala emerald emerged as the second largest source of gem-grade emerald.
Today, we will take you to learn more about Guatemalan jadeite.
1, "dangerous material" jade is
Guatemala jade, referred to as "dangerous material" jade, is a new category of emerald in recent years into the market. Its refractive index of 1.65-
1.67, relative density of 3.33-3.34, the main minerals for the jadeite, similar to the Burmese jade.
2, "dangerous material" jadeite color
Dangerous material jadeite color is rich and diverse, covering green, black, purple, pink and other colors. The most common on the market is green and blue tones. The overall color of Dangerous Material Jadeite is darker or bluish or greyish-blue because of the high content of iron ions and titanium ions. Dangerous material jadeite and Burma jadeite still have some difference.
Four, Japan, Kazakhstan, Russia and the United States
1, Japan
Currently the world's earliest jadeite processing is the Japanese excavation, but the vast majority of the Japanese jadeite small amount of poor quality, strictly speaking can only be called jadeite.
2, Kazakhstan
Kazakhstan's jadeite deposits were discovered in the late 1950s, but due to market and quality reasons, there is no scale
commercial mining. The vast majority of coarse particles, no water
3, Russia
Russian jadeite, also known as "Russian material", only a few can be issued jadeite certificate. The vast majority of Russian jade is far from reaching the level of commercial gemstones, at most, can only be regarded as "jadeite rock".
4, the United States
The United States jadeite raw stone texture is relatively dry, and the structure of the coarse, so most of them can only be used to do carving materials. It is also not up to the level of commercial gemstones. And Americans are not cold to jade. These places produce jadeite will rarely appear to reach the gem level of jadeite, most can only do carving level of craft raw materials, compared with the quality of Myanmar jadeite there is a big gap.
