Speaking of jade gambling stones, stones with white mist and white sand skin are one of the most popular jade gambling stones. Although the foggy jade stone is more gambling, it also adds a layer of decision and control to the gambling stone. Although fog can not directly affect the color, it is an expression of the old species of mountain and stone. Fog is also an important indicator for judging the quality, authenticity and authenticity of jade. It is also an important factor in determining the price. Therefore, understanding the formation and function of fog in jade stone is extremely important for the success of gambling. So what is "fog"? "Fog" refers to a layer of foggy opaque material present between the outer weathering shell and the inner jadeite, which is actually the result of the metamorphism of a jadeite mineral. In short, "fog" refers to the skin of jadeite. Weathered or oxidized) A semi-oxidized, slightly weathered jadeite layer between the interior of the jadeite (no weathering or oxidation) or meat. The fog of the jade stone is thick and thin, mainly white fog, yellow fog, black fog and red fog. People generally prefer white fog. One expert once said, "Where a stone with white fog is generally quite good, the water may be slightly higher, but overall it is good. And the white mist stone is generally good. It is white salt sand, mostly with good green, emerald or yang." So today we will talk about what is "white fog"? White fog generally appears under the yellow salt sand and black tungsten sand skin, the thickness is uncertain, but most of them are relatively thin. The white that is exposed after the outer skin is worn out, like the skin of garlic covered on the jade meat, called white fog. The color of the stone in this fog is light, but once the fog is removed, the color will be thicker. White fog is generally under the white salt sand and white pelicans. White mist is actually the product of weathering and diagenesis of jadeite gravel after weathering and sedimentation. It is the result of weathering and dripping of hard jade minerals. Studies have shown that the main mineral component of the white mist layer is jadeite, and there is no other mineral formation, so many experts and scholars believe that white fog is "during hydrothermal mineralization, late colorless jade along the fissure to the early colored emerald The product treated by percolation is then weathered and disintegrated along these fissures, and then the surface of the re-disintegrated gravel forms white sand, so from the surface of a gravel, there are white fog in some places, and some places do not." Obviously this reasoning is wrong, because many of the jadeite gambling stones are foggy, and all the jade white sand white mist stones are just impossible to disintegrate in the later white jade veins. The author believes that the gravel that forms the white mist and white sand is chemically low or almost free of iron, and the jadeite structure is dense. Therefore, in the process of weathering and leaching, there is no damage to the jadeite itself, but along the grain. The interfacial interface produces some micro-solubilization, which leads to the formation of fine voids in the crystal bond surface, which causes diffuse reflection under the optical, which makes us feel that the jadeite of this layer produces a white misty feeling. This may be the best explanation for the formation of white fog. Almost all of the white mist of jade is produced in the white sands of the jade gambling stone. There are also white fog under some white sands of the yellow sands or black sand skin, but this situation is very rare. The white sand and white mist of the jade gambling stone is basically the inner part of the jade meat. The color is very shallow and the water is good. It is a favorite among the Burmese jade gambling stones. Many bidders love this white stone because even This kind of stone has no color, and their water is very high. Moreover, this stone often has a scattered color (II stage jade) or veined emerald green (III stage jade) veins and veins. This is very white. The earthy jade and the bright emerald green are very good for planting water. Isn't that the high-end jade in our mind? And the main source of this white sand and white fog stone is the mouth of the wood in the old field. The picture below is the original type of stone, very good kind of water, white and pure ground color, bright and colorful green, so beautiful jade bracelet, how beautiful! Most of the white sand stones of the white sand are produced in the mouth of the wood. The most explosive stone is the veined greenish green belt (belonging to the third stage jade). The jade stone in the picture below weighs 2.45 kg, and the skin is yellow sand, but after washing it is white sand with white fog. The reserve price of the mark is Euro 168888. Finally, it is estimated by the mystery buyer with 500,000 Euro. More than RMB 2 million a kilogram, it is obviously used to make face materials. At best, this color is only medium-concentration apple green. Although it is not bright green, it is also the best jade stone that can be seen on the market. Another piece is the Mu Na stone that appeared on the public plate in October 2008, which is the original jade stone in the picture below. It weighs 5 kilograms, 600,000 euros, and the reserve price is 120,000 euros. It is a typical stage III jade, showing a green ribbon. But this stone is very gambling. According to conventional reasoning, this belt must be integrated into the inside, so the green part should not exceed 500 grams, even if there is 500 grams, that is, the unit price is more than 12 million yuan a kilogram, it is conceivable, If you want to cast this stone, at least from this price, forcing you to make a high-end jewelry-grade ring face, that is to say, with a single ring face 5 grams, the value of which is more than 100,000 yuan a face. The foggy jade stone is mainly from the old field. The stone of the four-way card in the old field has no fog, and the stone in the big valley has only a small amount of white fog. The stones in the Xinchang District, Xiaochang District, Houjiangchang District and Leifangchang District are rarely foggy. The top layer of Mosesa is generally white and very thin. There are also fewer cards, but it depends on the layer. However, many laymen believe that only the old stone is foggy, which is also inaccurate. Ok, we will talk about this for a while, then we will continue to introduce the yellow fog, black fog and red fog of jade stone and other gambling knowledge and tips.
