cause
The formation of hidden jade is very complicated. Four or five hundred million years ago, the physical and chemical reflection of underground magma occurred continuously, which made the composition of rock layers complex and diverse, and formed basaltic greenstone with rich mineral content. After the volcanic eruption magma cooled and solidified, the basaltic greenstone on the mountain rolled down the Yarlung Zangbo River due to crustal changes such as melting icebergs and earthquakes.
The stones left in this river have been repeatedly hit, washed and polished by snow and ice for thousands of years, forming a dark green or bright green jadeite stone with hard and bright surface, moist and delicate surface and different shades. Because the formation of hidden jade is complex, rich in trace elements and rich in stripes, it is very difficult to make artificial fraud. The unique attributes of Tibetan jade also exempt collectors from worrying about the authenticity of Tibetan jade.

Hidden jade is big and small, big like a stone, small like a fist like a pearl. There is a layer of dark green or dark black "Bao Gong Black" spots on the surface, dark green spots similar to frogs and snakeskin, and some yellow spots with cauliflower, so some people call them frog green and snakeskin green. Other color patterns are like Gu Mei Pride, and some have veins between Bai Shiying, forming patterns. This kind of jade is difficult to form, with high hardness and fine stone.
Extended data
Dark green jade is a kind of pure natural rock native to jade mine. It is the product of the integration of the essence of the sun and the moon and the aura of the earth for hundreds of millions of years. Because of its special pharmacological effects, it is called "Yao Wang Shi" by local people. Jade not only has magnetization function, but also has detoxification function. It contains not only jade components, but also 26 trace elements such as calcium, magnesium, iron, zinc and selenium.
It didn't have any function when it evolved, just a fog, which integrated many functional elements. Dark green jade is also called near dark green jade, and its primary colors are only white and green. White as leisure, comparable to suet jade; Crystal green, dare to compete with jade. Later, due to crustal changes, the metal ions and pigment ions of these minerals infiltrated and migrated along the cleavage cracks of jade due to the interference and erosion of surrounding minerals.
Over time, metal elements are oxidized and hydrolyzed, which makes them precipitate in jade and exist in the form of dispersed oxides, blending with the components of jade, making the original jade "black".
Because of the large proportion of magnets, graphite and biotite, and the active metal ions, dark green is the main color of jadeite. Although dark green jadeite has been unrecognizable by other intervention methods on the basis of primary colors, it is also famous for its special effects. But once the camouflage is stripped off, all the used dark green jadeite will gradually return to white green, and a jade cup will be as bright as green or as white as snow after long-term use, and black will no longer exist.
The restored dark green jadeite will have greater ornamental value and collection value. This is the truth that "people are matched with jade, and jade is priceless". Black in dark green jade is a secondary color, that is, it is not its true color. The secondary color pigment ions are very active and have great affinity for human body. After the raw ore is treated by mineral element catalysis and grinding resonance technology, the exchange of elements with human body will be faster
After these colored elements enter the human body, they can effectively remove impurities in blood, eliminate all kinds of toxins, promote blood circulation and strengthen hematopoietic function, thus delaying the aging process of human mechanism and preventing and treating various diseases. Every cloud has a silver edge, a dark green jade, which has been verified by practice, and its unique efficacy of treating diseases and preventing diseases really deserves its reputation! The primary minerals of dark green jadeite are rare in the world. At present, only Kunlun Mountain in China and Brazil in the United States have few reserves.
As early as 1700 years ago, dark green jade was widely used to treat diseases in China, and its minerals were mined. At the end of the 20th century, the primary dark green jade mine was discovered, with a reserve of about 36,000 tons. Because the available minerals are produced after a long time, the dark green jadeite primary ore is also a non-renewable resource, so it is extremely precious.
