1, what is the night pearl "night pearl" is in the dark, the human eye can see clearly, natural, can shine on its own jewelry. In ancient times, "Night Pearl" was also known as "Luminous Bi", "Bright Moon Pearl" and so on. The famous "Night Pearl" includes "Sui Zhu", "Hanging Dawn", "Heavy Thorn Bi", "Jade of Stone Phosphorus" and so on. The "night pearl" circulated in China's folklore has a strange luminous performance, which can emit a variety of colors in a lightless environment. The "Night Pearl" is the most mysterious, rare and precious treasure in the 5,000-year history of Chinese civilization, and is privately owned by the imperial power. "Night Pearl" has a deep historical background and cultural connotation.
2. According to historical records, the night pearl in the allusions of the dynasties and dynasties has appeared as early as the prehistoric Yan Emperor Shenjia, such as the king of the Shennong clan with stone balls known as "night mines". The Spring and Autumn Warring States Period, such as the "Hanging Dawn" and the "Wall of Weeping Thorns", are of great value, comparable to the clan bi. At that time, only the great official Tao Laigong (Fan He) and The Price Dun (great merchant in the Warring States period) could afford to buy it. The Jin Dynasty once used the "Wall of Weeping Thorns" as bait to "fake heads and Yu to make up". Doctors of Chu, Qin, Wei and other countries once used the pearl of the night to imply philosophy and discuss major national events. Qin Shi Huang buried the Night Pearl and "replaced the anointing candle" in the mausoleum. Empress Dowager Han's younger brother Guo Quan "hung pearls and hanging in all directions, seeing the stars during the day and the moon at night" to show off his wealth. Wu Zetian gave Xuanzong the jade dragon in the night pearl, and Xuanzong returned to his son (Sejong) a clear pearl, illuminating a room. When Tang had a car, a night pearl called "Water Drop" sold for hundreds of millions of dollars. During the Song Dynasty, the imperial family was particularly happy with the night pearl, of which the Night Pearl of Genghis Khan was stolen in Taiwan, and then the case was solved and returned to the original owner. Yuan Ming sent officials to Sri Lanka to buy ruby night pearls and garnet night pearls. The Cabinet of the Ming Dynasty once had several emerald night pearls, and the night was as bright as a candle. Some people regard it as a treasure, and some people abandon it as a treasure. In ancient times, some people did not know treasure, and once abandoned the bay of the hanging dawn at night. An old farmer in Wei Guo got a pearl with a diameter of a foot, and when he saw the night light, he threw it into the far field. Some people also regard the night pearl as a "curse of water" and "hit the sand and gravel". Although some are just legends, the Pearl of the Night has become a culture of its own in the history of our country with its beauty, nobility and mystery.
3, why can the night pearl shine What is the substance of the night pearl, and why can it shine? Luminous pearl is a fluorite mineral, and the reason for the luminescence is related to its containment of rare earth elements, which is caused by the movement of electrons related to the mineral. When the electrons in the mineral are stimulated by external energy, they enter the high-energy state from the low-energy state, and when the external energy stimulation stops, the electrons turn from the high-energy state to the low-energy state, and the process will emit light. Rare earth elements enter the fluorite lattice, which can emit light for dozens of hours after the fluorescent lamp, and the hood is glowing during the day, which cannot be seen during the day and seen at night. Those who carve fluorite into pearls are called night pearls, and those who carve jade plates are called night pearls. Therefore, the luminous pearl is not a pearl produced by the pearl mussel. The vast universe, there is no wonder, the mystery of the night pearl, is also a mystery of eternity. Since ancient times, people have often admired, amazed and confused people to talk about the night pearl. Some ancient literary works and some folk legends often paint the night pearl with layer after layer of mystery, and make up one after another gripping mythological stories. For example, there is a myth, legend says that the night pearl can illuminate the "dragon official like day..." The night pearl is also called "luminous wall", "luminous stone" and "glowing stone" in ancient Folk in China, and it is said that it is said that it is an extremely rare treasure in the world that can emit a strong light at night. The famous British scholar Joseph Needham recorded in his tome "History of Science and Technology in China" that ancient Chinese loved the night pearl produced in Syria, and it was nicknamed "Peacock Warm Jade". It is said that some people in India refer to the pearl of the night as the "snake's eye stone". According to the Japanese gemologist Reiki Toshi in 1916 in his compilation of the "Gem History", the Japanese night pearl is a special red crystal, known as the "sacred gem". The Pearl of the Night was originally collected from ore, but its distribution on Earth is extremely rare and difficult to mine, so it is particularly precious. Some ancient depictions of it have a strange flash of "side-view color blue; front-view color white". It is said that in ancient Greece and Rome, individual emperors embedded it in the palace or worn it on the crown, and some queens and princesses decorated it on jewelry or placed it in the bedroom, and used it as a national treasure to promote and praise. What kind of treasure is the Night Pearl? Ancient and modern Chinese and foreign statements are quite inconsistent. According to some experts, the night pearl is not as mysterious as some people boast, but several special minerals or rocks, which are processed by people to become bead-shaped. The light emitted by the night pearl does not illuminate the Dragon Palace as if it were day, as in the mythical legend. The luminous light is a larger night pearl, and in the dark, people can clearly view the prints at a distance of half a foot from it.
4, the essence of the night pearl In the world, there are thousands of mineral species in nature, of which there are more than twenty kinds of minerals, which can emit visible light under the stimulation of foreign energy, which is the luminescence of minerals. For example: fluorite, diamond, spodumene, emerald and other rare minerals. These luminous minerals have a long and short luminous time, and there is a difference between strong and weak. The most representative is a type of fluorite with the phenomenon of phosphorescence. It contains a variety of rare elements and is purple-red, pink-green, emerald green, dark green and spotted cloud white. In the crystallization process of fluorite minerals, there is a unique rare earth element that forms its own light source "luminous center" when it enters the lattice. It has a Hardness of 4 to 4.5 on the Mohs scale. Its stone appearance is colorful and colorful. After processing, it is processed into a small bead shape and a large ball shape. In the thick night, the beads are like stars twinkling, and the balls are like the moon spitting silver. And some high-quality fluorite phosphorescent beads, strong light, constant light does not fade, this is the world's legend of the "night pearl".
5. The largest night pearl in Shaanxi is known as the "Natural History Museum". During the National Day, Xi'an exhibited a pearl of night. This pearl of night is 1.6 meters in diameter and weighs 6.2 tons, and its whole body is green, smooth and glossy, as cute as a large emerald. Its light cannot be seen during the day, but at night, it naturally emits a fluorescence from green to white in the darkness, like a bright moon. This pearl of the night has been rated as the guinness of the shanghai world. It is reported that this night pearl was found by a miner in Yunnan, which was irregular in shape at the time, weighing more than 7 tons, and later became round after polishing.
6. The classification of the night pearl "night pearl" can be divided into two categories according to the different materials of the base body. １． Flora and fauna "Night Pearl": There are luminous people in the animal kingdom such as the famous fireflies, which are well known to everyone. Tang Dynasty Su Jaw's "Duyang Miscellaneous Compilation" records that in the first year of the Tang Dynasty Zongbao calendar, Nanchang State dedicated "Night Ming Rhinoceros". There are many luminous people in the plant kingdom, such as the "Compendium of Materia Medica" records that the "Muwei Xizhi", "Ginseng Zhi", and "Qiming Jiuguang Zhi" in the Ganoderma lucidum are fluorescent.
２． Mineral gemstone night pearl: From the perspective of solid state physics, the matrix material of the mineral "night pearl" is the activated crystalline phosphor in the inorganic salt crystal. The so-called activated crystal phosphor refers to the crystal that obtains the "luminous" ability due to the crystal lattice lattice distortion, and this distortion is mostly caused by the matrix containing certain heavy metal impurities (activators). For example, a small amount of Cu in ZnS can emit yellow-green phosphorescence, which is called the matrix, and Cu is called an activator. Due to the difference in activating the activators in the crystalline phosphor, the activated crystalline phosphor is also divided into two categories: (1) the permanently luminous night pearl: it does not need to be excited by any external energy, but relies on its own activator, such as 14C. ３Ｈ． １４７Ｐｍ． ２２６Ｒａ． ２３２Ｔｈ． Isogenic isotopes that emit light by spontaneous excitation. (2) Long afterglow storage type night pearl: the activator in the phosphor is not radioactive, and it must rely on external sunlight, ultraviolet rays and other light sources to excite it to emit light. At present, there are no less than 100 kinds of phosphors commonly used, and their chemical composition, in addition to alkali metal halides, are compounds of divalent metals (ca, sr, ba, cd, mg, zn) - sulfides, selenides, tellurides, silicates, aluminates, tungstates, phosphates and halogen phosphates. "Night Pearl" - this rare treasure, there have been many magical and beautiful legends throughout the ages, especially reflected in classical dramas, movies, novels and courts, involving many genres of Night Pearl. Since the emperors ascended the throne in ancient times and the crown prince returned to the dynasty, the night pearl has accompanied the emperor and the dragon son and grandson into the palace as the "treasure of the town and the country". Therefore, in ancient times, the night pearl became a symbol of the supremacy, supremacy, supremacy, supremacy, and supremacy of a country. Cloaked in a strong mysterious color, the night pearl is in people's traditional consciousness, which is both personified with the authority of the emperor and the holy and spiritual like the sun, moon, and stars of heaven and earth.
7, the magical legend of Yeming During the Eastern Han Dynasty, Xu Shen proposed that "jade, the beauty of stone, there are five virtues." In the early Spring and Autumn Period, Guan Zhong proposed that "jade has nine virtues." In the late Spring and Autumn Period, Kong Qiu proposed that "jade has eleven virtues". The saying of the virtue of the various families has provided a powerful spiritual pillar for china to love jade, worship jade, ritual jade, appreciate jade, play with jade, identify jade, and hide jade for thousands of years. In view of this, the Night Pearl is the treasure of the treasure and the king of the treasure in the treasure stone industry. In order to monopolize and monopolize this special right of successive emperors, ordinary people did not dare to ask questions, and even did not have the right to witness the style of the "Night Pearl". In order to please and cater to the favor of the emperor and generals, many literati and inkers collected a large number of materials about the night pearl, decorated and packaged it, making the already sacred and mysterious night pearl even more mysterious and confusing. The literati and wise men in the Hongmen Gang said: "There are 36 heavens and 72 heavens in the universe, for a total of 108 heavens and earth." The pearls of the night were picked up and bred, the light of the sun, moon, and stars in the sky, the moisture of the wind and rain in space, the glory of the mountains and rivers on the earth, and the spirit, god, soul, and spirit of the world. And the night pearl also preached in the legend: the night pearl is rare, rare, noble, gorgeous, mysterious because it has 36 colors, 72 xia, 108 lights. Talk about the nearest night pearl to us, the most famous, it is estimated that cixi mouth contains "Meiling jewelry shoes" it. According to the person who stole Cixi's tomb, that is, Sun Dianying, this bead is divided into two pieces, and when closed, it is a round ball, which is transparent and lightless, and when it is closed, it reveals a green cold light, and the hair can be seen within a hundred steps at night. In addition, there are records that it weighs four, two, two, and seven cents (133.4375 grams in total). No, it was the treasure she had placed around her that made her coffin open early. As for Song Meiling putting it on her shoes, she had only heard of it, so it was not known whether she was for beauty or to belittle the last Empress Dowager Xi who had brought calamity to the country and the people. Moreover, this woman, who was extremely regrettable in reality and rumors, once removed the four night pearls on the crown of the phoenix, intending to give them to the invaders in order to try to make peace. Fortunately, the palace maids around her actually had the heart to protect the national treasure, so that these four beads were lost to the people. It was discovered in 1964 and donated to the state free of charge.
8, the authenticity of the night pearl to identify the natural night pearl is extremely rare and rare, we identify its authenticity, in addition to the use of gemstone detection instruments for scientific identification, but also according to its many characteristics for identification.
Natural night pearl
(1) Light gray fluorite that must be illuminated for 15 minutes and can continuously emit light within dozens of hours.
(2) It has the phenomenon of phosphorescence, which can produce a quasi-effector of the night pearl.
(3) The color is beautiful, translucent, without any light, that is, permanent active luminescence, and the luminous energy is larger.
(4) Be sure to distinguish fluorescence and phosphorescence from phosphorescence, phosphorescence phenomenon is an applied light source, after removal can also maintain a certain luminous time.
(5) Observe its luminous length, uniformity, and half-life, and the length of afterglow.
Artificial night pearl
(1) Fill the fluorite cracks that do not emit light in themselves, and only emit light locally or linearly.
(2) After the luminous part passes through the light, the time is short and fleeting.
(3) Filled with luminous objects, flawed, there are obvious traces, naked eye viewing, relatively easy to see.
Due to the high value of pure natural night pearls, when identifying authenticity, it is necessary to hold a serious and serious attitude, and there should be an appraisal certificate issued by the national gemstone authoritative testing institution as the basis.
