The night pearl is a rare gem, which was called "following the pearl", "hanging the pearl", "hanging the ridge" and "bright moon pearl" in ancient times. Usually, the luminous pearl refers to fluorescent stone and luminous stone.
It is formed by some luminous substances in the earth after tens of millions of years, from the initial volcanic magma eruption to the later geological movement, gathered in the ore. After processing, the stones containing these luminous rare elements are what people call the night pearl, which is often yellow-green, light blue, orange and other colors. Fluorescent stone under white fluorescent lamp will emit beautiful fluorescence, which is obviously weak in the day and strong at night. In addition, some handicrafts also use the characteristics of fluorite to make some ornaments called "Night Pearl".
"Night Pearl" is a kind of natural gem, which can be seen clearly by human eyes in the dark and can glow by itself.
pearl
Pearl is an ancient organic gem. Mainly produced in mollusks such as pearl shellfish and Pinctada; The calcium carbonate-containing mineral (aragonite) beads produced by endocrine function consist of a large number of tiny aragonite crystals. According to the research of geology and archaeology, there were pearls on the earth 200 million years ago.
Question 2: Are there any pearls more precious than the night pearl? Strictly speaking, pearls are the night pearls.
Question 3: Is there really a night pearl in the world? Just when Changsha people lost their appetite for the fake night pearls that frequently appeared in the antique market, recently, Liao, director of the Provincial Collection Association and connoisseur of antique sundries, said that he saw a real night pearl: a gem and jade cold-light night pearl! The best in the night pearl! There is a magical story of a night pearl in the legend of Dayu's water control. Confucius' Shangshu and Sima Qian's Historical Records also describe the night pearl, which is an ancient and mysterious treasure. But is there really a pearl in the world? What does this "Best Night Pearl" look like? The reporter was full of doubts and went to find out on the evening of July 16.
The mysterious old lady grew up with a luminous pearl.
One day in late June, Liao, a connoisseur of miscellaneous antiques in Changsha, received a mysterious guest at work. Accompanied by five men and one woman, an old lady in her sixties took a 15-hour bus from Longshan County to Changsha, carefully untied a small black cloth bag from her waistband and handed it to Liao with both hands. When I opened it, it was a khaki ball with a diameter of 4cm and a weight of 125 g. Being enclosed in a black cloth bag for a long time, the ball can see a faint green light. Liao didn't care about this ordinary ball. The old lady said that she and her family have been observing at home for half a year, and they are shining every night. Jishou asked someone to identify him, and no one dared to draw a conclusion. He was also called an old fool by his son. He really doesn't want to. So I came to the provincial capital for expert appraisal, whether it was true or not, but I got my wish. The medicine agricultural hoe dug a "stone head".
The origin of this ball is quite complicated. In the summer of 2000, a 70-year-old medicine farmer surnamed Xiang in Longshan collected medicine in the mountain. When he went down with a hoe, he dug out a broken little black jar with a ball covered with mud. The old farmer washed it with mountain spring water, and when it was round, he took it back as a fun "stone head" (Longshan dialect, referring to stones) for his little grandson to play with. The little grandson rolled the ball into a bullet, and when he was tired of playing, he gave it back to his grandfather, who threw it into the drawer at will. Until the night of December 27th, 2002, the lights at home were not on. I went to the old man to look for candles and open the drawer. There is a slight green light inside, which turned out to be the "rock head" shining. Feel novel, bring the herbs to your county and spread them on the pillow to enjoy. A friend named Yang stopped by in the evening, saw it, and told him a friend named Zhou, who was cooking in a small workshop in Changsha. When Zhou went back to his hometown, he thought, I heard that there are so many fake luminous pearls hot-pressed with fluorescent powder in Qingshuitang, Changsha. Maybe it's true. If it is true, it will be worth a lot of money, so I bought it in partnership with my cousin named Liu. This cousin, surnamed Liu, is the husband of a mysterious old lady, so there is a scene where the old lady comes with a luminous pearl at the beginning of this article. Gems, jade, cold light and luminous pearls are the most precious.
According to legend, Genghis Khan has a luminous pearl, which is named "Zhu Zhen in Kowloon" because it is placed in a box with nine dragons. This pearl was exchanged for a diamond by a businessman in Taiwan Province province. In the Qing Dynasty, the phoenix crown of Empress Dowager Cixi was also inlaid with nine luminous pearls, about one centimeter in diameter. After the death of Cixi, the pearl in her mouth was stolen from Dongling by warlord Sun Dianying, and then fell into the hands of * * * politicians, whose whereabouts were unknown. In short, there are many historical legends about the night pearl, but it is difficult to verify because there is no real thing. What is certain is that the Night Pearl does exist, and it is a rare treasure.
According to relevant data, there are five kinds of luminous pearls, one is phosphorescent fluorite luminous pearl, which needs heating in a dark room to emit weak white light. One is calcite and diamond infiltrated with rare earth elements, both of which only emit weak white light. There is also a kind of pearl night pearl, which reflects light rather than shines. The most valuable are precious stones and emerald luminous pearls, which can emit green light. Besides fluorite, the first four kinds of luminous pearls are thermoluminescence, because they absorb higher external energy and then slowly release it with lower energy to form light. Gem is photoluminescent, even if the indoor light is very weak, it does not need illumination and heating, and the fluorescent green light gradually becomes stronger from weak. The appraiser stayed up for eight nights.
Liao didn't dare to be careless after accepting the great trust of the old lady. Observe the ball from 8: 00 p.m. to 3: 00 a.m. for 8 consecutive nights, and do not heat or heat the observation ball in the dark. And gathered people who observed and witnessed together at different times, and made a bold conclusion: this ball from Longshan is the cold light pearl of the gem! It is different from the fake luminous pearl and fluorite luminous pearl hot-pressed with fluorescent powder on the market.
On the evening of July 16, the reporter invited several colleagues to witness the whole process of the Night Pearl in a specific darkroom of the Radio and Television Center. At about 8: 30 pm, Liao took it out of the black cloth bag and the black paint box respectively ... >>
Question 4: Is the luminous pearl a light source? It is not generally believed that the night pearl is a special kind of pearl, but scientists have denied this view through research. Although pearls are crystal clear and round, bright in color and dazzling, they can't be "night pearls". The main component of pearls is aragonite (CaCo3), which is wrapped by many aragonite slices, and the large aragonite slices of pearls reach 1000 layers. Aragonite flake has strong reflection, which makes pearls look crystal clear, but it has no luminous function (some pearls contain a small amount of rare earth elements, which can produce fluorescence under external excitation, and it is impossible to emit light without external energy). On the contrary, because aragonite will turn into calcite, the color of pearls will turn yellow and lose its luster. Some people think that emeralds, red crystals, special diamonds, snake eye stones and Syrian peacock jade from India all contain fluorite minerals, which can become luminous pearls. Fluorite, whose chemical composition is calcium fluoride (CaCo3), can be excited to emit visible light under the irradiation of external energy (ultraviolet rays, X-rays, etc.). However, the essence of its luminescence is that the mineral lattice first absorbs high external energy, and then emits visible light with low energy when the surrounding light is dark. After the applied energy stops, it will take some time for the excited electrons in the crystal structure to fall back to the original ground state at a certain speed, so they can continue to emit visible light in a short time. But it has no luminous function itself.
Question 5: What is the material of the night pearl? I remember reading it on Bao Bo Art Network. This kind of pearl is basically the same as ordinary pearls. Natural pearls are foreign impurities absorbed by mussels. However, this impurity contains certain radioactive elements for some reasons, forming a special kind of pearl. When these radioactive elements decay, they emit rays. After the radiation hits some substances inside the beads, these substances will glow. Light energy comes from nuclear energy. Generally, these elements have a long half-life, so they can emit light for a long time. It seems that the method of artificial night pearl in that book is to intentionally implant radioactive substances into mussels.
Question 6: How is the night pearl formed? According to the expert appraisal of China Gemstone Association, Shenzhen Night Pearl is a fluorite mineral. The reason of its luminescence is related to the rare earth elements contained in it and the related electron movement in minerals. When the electrons in minerals change from low energy state to high energy state under the action of external energy, when the external energy stops, the electrons change from high energy state to low energy state, and this process will emit light. Rare earth elements enter the fluorite lattice and can emit light for dozens of hours after being irradiated by fluorescent lamps. It glows during the day, but it is invisible during the day and visible at night. Those who carve fluorite into pearls are called night pearls, and those who carve jade plates into pearls are called night pearls. Therefore, the luminous night pearl is not a pearl produced by pearl mussels.
Question 7: The night pearl is one of the most famous treasures in ancient China. It is also called amphibole and luminous jade in China. Legend has it that it is a natural treasure that can shine at night. In fact, the luminous pearl not only exists in Chinese civilization with a long history, but also can be found in ancient Indian civilization, ancient Greek civilization and ancient Jewish civilization. The earliest record of the night pearl in China is the Warring States Policy in the Spring and Autumn Period and the Warring States Period: the king of Chu once sent messengers to the king of Qin for two treasures, one of which is the night pearl, that is, the night pearl. It can be seen that the value of the night pearl is no less than that of jade, which is generally owned by the royal family. There is also a description of the Night Pearl in Historical Records: Qi Weiwang and Wang Wei met in the suburbs, and Wang Wei boasted that he had ten "pearls with an inch diameter", each of which could get on the bus twelve times before and after. The bright moon and pearl, three feet in diameter, shines thousands of miles. Although this is an obvious exaggeration, it also reflects the important position of the night pearl to some extent. With the night pearl, it is equivalent to having great wealth. It is said that there is a kind of night pearl in Qin Shihuang's sacrificial offerings, which is used to "replace ointment candles" in the mausoleum. The most famous luminous pearl in modern times is the commemorative luminous pearl in Cixi's mouth. Empress Dowager Cixi was buried in Yuling in the east of Qing Dynasty after her death. There are a lot of rare treasures in her funerary objects, including the priceless night pearl. Legend has it that the night pearl can produce cold and prevent heatstroke, so after Cixi's death, she put it in her mouth to prevent the corpse from rotting. 1928, the warlord Sun Dianying broke into the mausoleum of Cixi, destroyed the coffin and stole most of the buried treasures, including this precious luminous pearl. Sun Dianying's confession is recorded in Shanpu's "The Treasure Robbery of Sun Dianying in Dongling": "She (Cixi) has a luminous pearl in her mouth, which is divided into two pieces. When it is closed, it is a ball, transparent and dull. When it was closed, it showed a green cold light, and her hair could be seen within a hundred steps at night. I heard that this treasure can keep the body from melting. No wonder after Cixi's coffin was split open, Lafayette seemed to fall asleep. It's just that when I see the wind, my face turns black and my clothes are not suitable. " As the most enjoyable Empress Dowager Cixi in history of qing dynasty, Cixi tried her best to find all kinds of rare treasures all her life, but she never thought that it was this most famous treasure that took her life after her death. At that time, after the grave robbers opened Cixi's coffin, they scrambled to grab the funerary objects in the coffin. At first, they didn't care about Cixi's body, but when they rummaged around, they found that her mouth was shining with dark blue light, and someone exclaimed on the spot that it might be a priceless pearl. Sun Dianying's adjutant, surnamed Liu, quickly put his hand into Cixi's mouth, trying to dig out the luminous pearl, but the smooth beads slipped into Cixi's throat and could not be taken out with great difficulty. So, adjutant Liu simply took out a sharp knife and stabbed it into Cixi's mouth. Then he viciously cut a knife left and right, and cut a big hole in her mouth before taking out the night pearl. It is said that the night pearl is as big as an egg, and the blue-green light illuminates the faces of onlookers. Only this luminous pearl was entrusted by Sun Dianying to Dai Li to give to Song Meiling. Later, it was said that the Night Pearl was brought to the United States by Song Meiling, and its whereabouts were unknown. In fact, in addition to this buried night pearl, Cixi has nine others, and because they are slightly smaller, they are embedded in the rockhopper. 1900, when Eight-Nation Alliance invaded China, Empress Dowager Cixi took four night pearls from her rockhopper in order to please foreign invaders, and ordered a maid-in-waiting surnamed Wang to leave the palace and give them to foreigners. It is rare that the ladies-in-waiting are young, but they have a patriotic heart. She couldn't bear the national treasure to fall into the hands of the invaders, fled with pearls, remained anonymous and struggled. Before she died, she gave the little pillow with the night pearl to the Wu couple who had been taking care of her. Before she could explain the secret, she stopped breathing. It wasn't until they cleaned their pillows at home that the Wu couple found the pearls inside and immediately gave the national treasure to the local people unconditionally. According to these records, there seems to be no doubt about the existence of the night pearl, but there are different opinions at home and abroad. Some experts even verified that the night pearl is not as mysterious as people imagined and boasted. It is only composed of several special mineral rocks. After people's processing, it has become a round pearl shape. There are generally three opinions about the nature of the night pearl: First, the night pearl is a fluorite mineral, and the reason for its luminescence is related to its rare earth elements and the related electron movement in the mineral. When the electrons in minerals are influenced by external energy, they change from low-energy state to high-energy state, and when the external energy stops, they change from high-energy state to low-energy state. & gt
Question 8: Is this the night pearl? Be careful that it contains radioactive substances!
In my impression, the night pearl is called the' night pearl' because it is the eyeball of a boa constrictor or a big pearl. This thing you show looks like a stone or something. I think we should pay attention to unknown luminous objects! Be careful of substances that are harmful to your health. If necessary, find someone to identify what radiation is.
Question 9: Are these night pearls valuable? This is true for the night pearl, which is very valuable; The bidding price in the general genuine market is around 10000; Above this price, there can be a large supply in the market!
