One and a half gambling
Ming material refers to the raw material that has been cut from the jadeite original stone, or the original stone that has been completely stripped, which is called "a good start" in the industry; Its characteristics are relatively clear, although it still has certain gambling, but the risk is relatively small.
Semi-gambling stone means that the original jade stone has been cut with a small mouth, or one or several small mouths have been wiped open, which is called "window opening" in the line; It is often manifested in the emerald green of the mouth, or the jade quality of "window opening" is better, or there is "yellow fog" (that is, yellow jade) under the skin of the mouth, but some mouths are neither green nor jade, and the jade quality is not good; This kind of semi-gambling stone, regardless of the performance of wiping the mouth, is more risky.
Gambling stone refers to the original jadeite stone with skin, which is hardly rubbed or only rubbed with a thin layer of skin. It is still difficult to see the jade quality and color inside the original stone, and it is difficult to judge its value. The industry calls it "gambling stone", that is, all gambling; It is characterized by relying on experience and eyesight, taking chances, or talking about the probability of winning a bet. Generally, the success rate is very low and the risk is great. There are adjectives such as "one knife is rich and one knife is poor", "the madman sells the madman and another madman is waiting" and "crazy stone", so it is very tempting and irritating.
2. The color of jadeite wool
Jade, the king of jade, has ever-changing colors, including green, red, purple, blue, yellow, gray, black, brown, cyan and colorless. Crystal clear and colorless, moist and aura; Crimson represents auspiciousness; Violet symbolizes nobility and elegance; With green, precious and luxurious, there is charm; Green, flying and purple represent Fu Lushou; Green, emerald, purple and cyan are considered as symbols of Fulu's birthday.
3. Jade quality of jadeite wool
To judge the jade quality of jadeite wool, there are glass seeds and ice seeds with crystal clear water head, wax seeds and bean seeds with thin water head. It is also necessary to consider the change of jade quality under the original stone, because jadeite is a multi-stage jade, which causes the change of jade quality and color, and it is also ever-changing, which is also the reason why the original jade stone is gambling and irritating.
4. Selection of Emerald Wool
Jade wool is a very distinctive jade raw material, and its basic selection principles are as follows:
Look at the color first. Emerald, emerald and violet have the highest value, and its green color is divided into one to ten colors, and the price difference is several times. Feise and violet are also more precious.
Second, look at the quality and transparency of jade. The water head is divided into one to ten points, and its value is several times higher every time it is higher than one point.
Three: look at impurities, low value.
Four: it depends on cracks, which have a greater influence on the numerical value. If processing can be eliminated, it is worth considering.
Fifth, it depends on the purpose. If you directly collect the original jadeite stone, you can consider not cutting or just cutting a small mouth or wiping your mouth with a good kind of colored gambling stone: First, due to the great risk of gambling stone, don't take the mentality of "getting rich with one stone" as the mainstay, and bet stone rationally; Second, we should pay attention to analysis, research and summary, and learn more and practice more; Third, pay attention to the fraud of gambling stones, such as fake skin and fake "window green"; Fourth, pay attention to Burmese nephrite with leather shell.
If it is a small ring fabric, the color water is definitely more graded; If you are making small pendants and bracelets, the colored water must be in place. If you are making jewelry, the color water of the jadeite wool used for middle and high-grade jewelry must be high-grade, and the jadeite wool used for middle and low-grade jewelry should be delicate and distinctive. If you buy jade wool for public auction of jade, try to choose bright materials and semi-gambling stones, which are better to sell.
Five jadeite wool selection risk
The selection of jadeite wool is an investment project, and the risks are generally relatively large. Experts' suggestions are: be rational, stress principles, accumulate experience, analyze and judge in detail; The risk of relying on luck is almost 99%, which is a story that happens almost every day in the gambling stone market.
Little knowledge of jadeite original stone mine mouth: Nanqishi mine mouth
Nanqi is one of the most important sites in Xiaochang District, located in the south of Damakan District and on the left side of Endo Lake. There are three layers of ore: the first layer of yellow sand skin, the second layer of yellow red sand skin and the third layer of black sand skin. The stones produced by Nanqi are yellow sand skin, yellow red sand skin and black sand stone. Emerald with green belt and yellow and green is a typical high-value variety in this respect. Emeralds with green color are mostly blue-green because of their high iron content; Yellow-green jadeite is rich in color and strong in layering. That kind of stone is generally older.
It should be pointed out that Nanqi is not tender, but a little tender compared with the varieties with skins. Because of the high iron content, yellow-green things are often formed, and the stone primary mines are all from Dumao Ganxi mining area. The reason why Nanqi wax shell is complete is because the stone is precipitated after long-distance transportation, and the shell is not scraped, which is easy to form a complete wax shell. Most of the black sand in the old field is unshaven stone, so it is not easy to form a complete wax shell.
Characteristics of the original stone in Nanqichangkou
1, the stones in Nanqi are foggy, thin, old and tender.
2. Nankishi stones are all small.
3. South Seven Green is blue, gray or even black. The color of the stone in Nanqi is red, indicating that it contains high iron content.
4. The powder scraped by Nanqi black sand is grayish green, which is called grayish black sand. (It seems that in my impression, the wax shell of Nanqi is generally complete, unlike the base of Mowan, which is semi-cemented, and the black sand is as thick and foggy as black paint. )
5. There are many glutinous bottoms in Nanqi Black Sand (there are many fine beans such as Lao Pagan and Mo Wanji).
6. The stones in Huangshapi are mostly water stones and water stones. Most of the stones in the black sand skin are turned upside down. The sand skin is thin and sometimes foggy.
