1, jet is nephrite, so the first item is to identify whether it is nephrite;
2. Black jade contains a lot of other minerals. The real black jade should be completely black and opaque, and the spotlight should not be jasper green.
"What is the real jet? In fact, the name of jet is called by color. There are jet with white jade and jet with jasper. These two different kinds of jet can be called jet. The value of nephrite is higher than that of white jade, and the value of jasper is lower than that of white jade. High-grade jasper (finished product with average thickness) will appear bright blue without strong light, and the all-ink jasper with good texture is not the high-grade jasper; There are many all-ink jasper with poor texture, which are mostly used as stone. The jet with white jade bottom (or blue white jade bottom) is slightly different from ink, ink gathering and full ink. Mo Dian Mo Yu is what Xuanzang, a monk in the Tang Dynasty, called "Jade Jade". Someone asked before, "Do you have purple jade and hetian jade? The photo displayed is "Jade". If you look at it with a strong light and a magnifying glass, you can see that countless tiny graphite dots are evenly distributed, so the appearance is gray instead of purple, and Hetian jade is not purple.
Black jade with white jade bottom (or blue white jade bottom) is slightly different from ink, ink gathering and full ink.
Only a few white jade have good quality and full ink color. In fact, the so-called "blue and white jade" in the original stone market often appears in the so-called jet. Blue and white jade is a kind of white jade or blue and white jade with black stars, moire or stripes, which can be called "blue and white jade". If blue and white jade is black (gray) and white, some people call it black and white jade. Of course, the black part is jet black, and the gray part is jet black.
The jet at the bottom of jasper is bright blue.
There is also a black kava stone, which is full of ink, but not hard enough to be called jet.
There are many kinds of jet. Because it is naturally formed, the texture (commonly known as meat quality) of each jet is difficult to be the same. We can roughly divide it into four types:
◆ Black jade and white jade bottom: This kind of jade is black jade, black and white are very distinct, the stripes are clear for the top grade, and some are mixed with black and white, which is inferior. Of course, the hardness, chromaticity, density, wettability (oiliness) and appearance of jadeite will all affect the value of jadeite. There are also blue and white jade or mixed jade, collectively referred to as blue and white jade. Good blue and white jade is also valuable. At present, there are few jet jade on the market, and the price is very expensive. The market is out of stock, and no similar jade can be found.
◆ jet and jade bottom: According to customers, this kind of jade is commonly known as jet or turquoise jade. This kind of jade is unique in that it is black and blue in color under the irradiation of light or sunlight, which is very beautiful. It is also called color number difference, because the background color is jasper. If there are a lot of black ingredients, it is called black jasper. If blue is more than black, it is called turquoise. In fact, it belongs to the same kind of jade, and the names are divided according to the number of colors. This jade is on the second or third floor of Yuan Qi Building, Dunhua South Road, Taipei. You can see that there are jasper counters, but the jasper they sell is Canadian jasper. Creative, I heard that it sells well, but the quality of Canadian jasper is not as good as Hetian jade. The biggest difference between Canadian Jasper and Tian Jasper lies in density and moisture. Hetian jade is moist, oily and feels good, while Canadian jasper is not moist and dry to the touch.
◆ Momo Rain Land: This kind of jade is a whole piece of jade, which is pure black inside and outside. No other colors are mixed. Nowadays, there are very few black jade, and pure black jade like ours is very rare, so black jade is now bought and sold in grams.
◆ Gobi Moyu: As the name implies, this kind of jade is produced in the Great Gobi and is also graded. But the particularity of Gobi jet lies in its hardness and density. After hundreds of millions of years of wind, frost, rain and snow, jade is very good, but Gobi jet is really hard to find, especially good Gobi jet, which is really hard to get, so good Gobi jet is expensive.
★ The above four kinds of jet are only rough classification and simple description, and there are many kinds. Every kind of jet must also be graded. From color, density, moisture, appearance, size, etc. , and subdivided into the best, top, middle and bottom. Due to different grades, the prices are different.
Jade features: dense and moist, full of color, crystal clear and transparent. Cotton ink in jade is the natural growth texture of jade, which embodies the beauty of nature and is the basis for distinguishing quality from authenticity [edit this paragraph] jet has a rich history. Since Qin and Han Dynasties, jet has been mined. According to the county records, "minerals are located in the north of the county, and miners from all counties come here to carve and ponder, named jet." It is also the famous "hometown of stone carving" in China. Fuping Moyu and his works also have a glorious history in the history of Chinese civilization. Anbeilin, known as the largest treasure house of stone carving art in China, has more than 700 pieces of cultural relics, of which more than 80% are made by Fuping Moyu, Qin Lisi's Engraving Stone on Yishan, Cao Quanbei in Heyang, Ou Yangxun's Huangfushengchen Monument [2] and many pagodas in Yan Zhenqing.
Qinchuan, 800 miles in central Shaanxi, is known as the "Open-air Stone Carving Art Museum". A large sculpture group, a large number of stone carvings, statues and horse nails, from Qiaoling 15 meters high and 40 tons of huabiao to the mysterious wordless tablet in front of Ganling, and the national treasure "Six Horses in Zhaoling", are all made by Fuping Moyu. In Qing Dynasty, Li Hanlin Silver Capital was made in Tang Ling. Mo Yu's Nine is also! [Edit this paragraph] Before the legend of Mo, a fairy suddenly landed in the county (now Fuping County). This fairy is not only graceful and beautiful, but also has some skills of Shi Chengyu.
Yang Pin County is a place with beautiful scenery. As soon as the fairy arrived in Yang Pin County, she was fascinated by the charming scenery here: Baling jathyapple, Baofeng Stone Man, Phoenix spreading its wings, golden millet morning bell, cave book sound, golden rooster crowing, golden turtle longevity and Longquan Waterfall flowing. Fairy can't swim all the time and can't see enough. Unconsciously fascinated by the beauty of the world, I never want to go back to the Heavenly Palace. Every day, fairies enter the pine forest, play in streams, visit temples, climb dangerous peaks, float in the air, leave leisurely and freely. Really happy. Over time, people found that wherever the fairy rested, the stones turned into beautiful jade with bright paint and ink. Because the fairy is crazy about beautiful scenery and free life, she actually lives in Phoenix Mountain. During the day, the fairy turned into a graceful rock and witnessed the endless beauty of the world. Become a fairy at night and sing and dance softly. Since the arrival of the fairy, Phoenix Mountain has suddenly become a place of singing and dancing, with birds singing and flowers fragrant, and the mountains are green and green, surpassing Suzhou and Hangzhou. Because of this, Tang Zhongzong chose Zhong Ling, a beautiful land of geomantic omen, as his graveyard.
Since the fairy came to Phoenix Mountain, all the stones on the mountain have become Baoyu. Masons have gone up the mountain to stone, chisel jade and carve statues. Their sculptures are lifelike, delicate and touching, black as paint, bright and clean, and many merchants come here. Wen Xun, Emperor of Han and Tang Dynasties, also used Fuping Moyu to build his own tomb. The black jade carving of Phoenix Mountain swept through Guanzhong and became famous all over the country.
At the foot of the Phoenix Mountain, there is a land owner Diao, who loves money like life and has a vicious heart. I heard that there lived a fairy who could recognize Shi Chengyu on the Phoenix Mountain. He thought: if you can bring the fairy home, won't all the hard stones in his house become beautiful jade? The more he thinks about it, the more beautiful it is. He tossed and turned until he didn't sleep a wink all night. At dawn, he took the rope and hid it in the cave where the fairy lived. He stared at the eyes of two thieves like a mouse, waiting and waiting until the sun set and the fairy came back. The fairy took off her black veil, spread it on the slate, and slept with the clothes, trying to eliminate the fatigue of the day. Unexpectedly, just lying down, Diao Landlord suddenly jumped out of the darkness. When the fairy found someone in the cave, she was surprised and flew out of the cave and floated away. In her hurry, the fairy forgot the black veil on the slate. When the naughty landlord saw the fairy escape, he chased her all the way. From Phoenix Mountain to Xinfushan Mountain, from Jinfu Mountain to Jinping Mountain, I chased and chased, panting, my legs were weak, and I couldn't run any longer, but I didn't even catch the shadow of the fairy. Diao landlord's eyes turned, and he suddenly remembered the ink yarn left by the fairy in the hole and ran back desperately. When Diao landlord ran back to the cave, there was nothing in it.
It is said that this fairy is the niece of the Queen Mother. Mosha is a protective magic weapon given to my niece by the Queen Mother. This ink yarn has the ability to touch stones, that is, black, and Shi Chengyu. The queen mother heard that there were only four kinds of jade in the world, red, yellow, green and blue, and there was no jet, so she ordered her niece to come to the world to order jet to make up for it. Unexpectedly, I met this naughty landlord and left Mosha on the Phoenix Mountain. After the fairy left, the ink yarn melted like snow and gradually infiltrated into the rock. Since then, the stones all over the mountain have become black as a mirror. Phoenix Mountain has also become the famous hometown of stone carving in China.
