The night pearl is a rare treasure, which was called "following the pearl", "hanging the pearl", "hanging the spine" and "bright moon pearl" in ancient times, and its professional name is fluorescent stone. It is made of some luminous substances in the earth after millions of years, from the initial magma eruption to the later geological movement, and gathered in the ore. The stone containing these luminous rare elements, after processing, is what people call the luminous pearl, scientifically called fluorescent stone, which often has yellow-green, light blue, orange red and other colors. When the fluorescence is taken under a white fluorescent lamp, it will emit beautiful fluorescence, which is obviously manifested by weak day and strong night.
What is the night pearl?
"Night Pearl" is a natural jewel that can be seen clearly by human eyes in the dark and can glow by itself. In ancient times, the "night pearl" was also called "luminous jade" and "bright moon pearl". The famous "night pearl" includes "following the pearl", "hanging Li", "the stone with heavy spines" and "the jade of stone and phosphorus".
The "Night Pearl" circulated among the people in our country all have strange luminous performance, which can emit glittering and translucent brilliance of various colors in a dull environment. The "Night Pearl" is the most mysterious, rare and precious treasure in China's 5,000-year history of civilization, and it is privately owned by the imperial power. "Night Pearl" has a profound historical background and cultural connotation.
According to historical records, during the Spring and Autumn Period and the Warring States Period, the "Night Pearl" has been regarded as a "famous vessel in the world", and its precious value is on a par with that of the "Heshi Wall".
Classification of night pearl
"Night Pearl" can be divided into two categories according to the different matrix materials.
1.Animal and plant "Night Pearl": It is well known that there are luminous people in the animal kingdom, such as the famous fireflies. In the Tang Dynasty, Su Jaw's Duyang Miscellaneous Compilation recorded that in the first year of Tang Daizong's Baoli, Nanchang presented a "night-bright rhinoceros".
There are many luminous plants, such as "Mu Wei Xi Zhi", "Shen Cheng Zhi" and "Qi Ming Jiu Guang Zhi" in Ganoderma lucidum recorded in Compendium of Materia Medica all emit fluorescence.
2. Mineral gemstone luminous pearls: From the perspective of solid physics, the matrix materials of mineral luminous pearls are all activated crystalline phosphors in inorganic salts.
The so-called activated crystalline phosphor refers to the crystal that obtains the "luminescence" ability due to the lattice distortion of the crystal lattice, and this distortion is mostly caused by some heavy metal impurities (activators) contained in the matrix. For example, a small amount of Cu in ZnS can emit yellow-green phosphorescence, which is called matrix and Cu is called activator.
At present, there are more than 100 kinds of phosphors in common use, and their chemical components are all divalent metals (Ca. Sr? Ba．Cd．Mg．Zn．) compounds-sulfide, selenide, telluride, silicate, aluminate, tungstate, phosphate and halogen phosphate. "The Night Pearl", a rare treasure, has many magical and beautiful legends throughout the ages, especially in classical dramas, movies, novels and palaces, and there are many genres involving the Night Pearl. Since ancient times, emperors have ascended the throne, and princes have returned to the DPRK. As a "treasure of the town", the night pearl has accompanied the emperor and his sons and grandchildren into the palace. Therefore, in ancient times, the night pearl became a symbol of a country's supreme, supreme, supreme and revered rights and wealth. In people's traditional consciousness, the night pearl covered with a thick mystery personifies the authority of the emperor; It is also as holy and deified as heaven, earth, sun, moon and stars.
Because the night pearl is rare and rare, it is shrouded in a mysterious color, so the world has a very strong desire and curiosity for it. In daily life, many relatives and friends, as well as treasure lovers and collectors frequently ask me questions about the night pearl. In order to help you understand the basic knowledge of the night pearl and solve the mystery of the night pearl, my article will be used as a discussion and superficial interpretation of the mystery of the night pearl.
Rare mineral characteristics of the night pearl
In the world, there are thousands of kinds of minerals in nature, including more than 20 kinds of minerals, which can emit visible light under the excitation of external energy, which is the luminescence of minerals. For example: fluorite, diamond, spodumene, emerald and other rare minerals. These luminous minerals have long or short luminous time, and there are strong or weak differences. The most representative is fluorite with phosphorescence. It contains all kinds of rare elements and is purple, pink, green, dark green and mottled. During the crystallization of fluorite minerals, a unique rare earth element enters the crystal lattice to form its own "luminous center" of light source. Its Mohs hardness is 4~4.5. Its stone appearance is colorful and colorful. After processing, it is small and bead-shaped, and large and spherical. In the thick night, the beads are like starlight, and the ball is like a bright moon spitting silver. Moreover, some high-quality fluorite phosphorescent beads are bright and persistent, which is the legendary "night pearl".
The magical legend of the night light
During the Eastern Han Dynasty, Xu Shen put forward that "the beauty of jade and stone has 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 put forward that "jade has eleven virtues." . The theory of jade virtue of various schools has provided a powerful spiritual pillar for our country to love jade, worship jade, gift jade, enjoy jade, play jade, learn jade and hide jade for thousands of years. In view of this situation, the night pearl is the king of treasures in the gemstone industry. In order to monopolize and monopolize this exclusive right, the ordinary people are afraid to ask for it, and even have no right to witness the elegance of the "night pearl". In order to please and cater to the favor of emperors and princes, many literati collected a large number of materials about the night pearl, decorated and packaged it, making the already sacred and mysterious night pearl more fascinating and confusing. Scholars in the Hong Men Guild said: "There are 36 days in the universe, and there are 72 underground demons, which is *** 108 heaven and earth. The pearl of the night picks and breeds the bright light of the sun, the moon and the stars in the sky, the moist of the wind, the rain and dew in space, the brilliance of the mountains and rivers on the earth, and the brilliance of the essence, spirit, soul and spirit in the world. Moreover, in the legend, the Night Pearl preaches: The Night Pearl is rare, rare, noble, gorgeous and mysterious because it has 36 colors, 72 sunsets and 108 light. Therefore, what magical and precious thing in the world can rival the night pearl?
Identification of the authenticity of the night pearl
The natural night pearl is extremely rare. We can identify its authenticity not only by using the scientific detection instruments of gemstones, but also according to its many characteristics.
Natural night pearl
(1) Light gray fluorite that can continuously emit light for dozens of hours after being illuminated for 15 minutes.
(2) Those with phosphorescence phenomenon can not only produce the quasi-effect of the night pearl.
(3) Beautiful color, translucency, permanent active luminescence without any illumination, and large luminous energy.
(4) It is necessary to distinguish between fluorescence and phosphorescence of fluorite. Phosphorescence is the effect of an external light source, and it can maintain a certain luminous time after being removed.
(5) Observe its luminous length, uniformity, half-life and afterglow.
Artificial luminous pearl
(1) Filled with fluorescent powder in fluorite cracks that do not emit light by themselves, only local or linear light is emitted.
(2) After the light-emitting part passes through the illumination, the time is short and fleeting.
(3) Filled with luminescent materials, the flaw is clear and there are obvious traces, which are easy to see through with naked eyes.
Due to the high value of pure natural night pearl, we should take a serious and earnest attitude when identifying the authenticity, and should have an identification certificate issued by the national authoritative gemstone testing institution as the basis.
The Value and Evaluation of the Night Pearl
As the old saying goes, "things are rare." A pure natural night pearl, since ancient times, can be said to be asking for a price. Natural night pearl, its rare and exotic factors, cultural connotation factors, value preservation and appreciation factors, make it priceless.
After China's entry into WTO, all walks of life should be in line with international standards, and China's gem and jade industry will also enter the world from the market economy. The luminous pearl of the king of jewelry will also go abroad as a "jewel pride and darling".
On June 20, 2002, the national gem newspaper published an article entitled "Pearl Value Geometry? , the US price is in the imperial city! " According to the report, China Gemstone Association held a special seminar for the value evaluation of the night pearl. The experts at the meeting made authoritative argumentation speeches respectively. According to the experts, among all the jewels recorded in the book "The Theft of Cixi Mausoleum" in the Qing Dynasty, one of the night pearls weighed 422 yuan and 7 cents, which was about 133.4375 grams. At that time, it was priced at10.802 million silver. By the first year of Guangxu, the value of the night pearl had increased tenfold. By 37 years of the Republic of China, it had increased by 100 times.
In the early stage of the seminar on the evaluation of the value of the luminous pearl, an American organization issued two evaluation reports on the fluorite luminous pearl, one with an evaluation of10.30 billion US dollars and the other with an evaluation of 280 million US dollars, and solicited the opinions of experts in the gemstone industry in China.
There is another report: The article "The Emergence of Giant Night Pearl with Rare Treasures" in Collection Magazine No.33 mentioned that a light gray gem night pearl weighing 2,800 grams, which can continuously glow within 72 hours after being illuminated by 15 minutes, has been confirmed as the largest and priceless rare treasure in the world at that time. It was sold for 40 million RMB for the first time, and then sold to a French collector at a high price of18 million USD.
In addition, the 63rd issue of Auction Collection Weekly of China Commercial Daily published "Rare and Precious Night Pearl Shines" and Beijing Daily published "The World's Largest Night Pearl Publicity: 40cm in diameter, with an estimated value of over 10 billion".
Experts have said: Because the night pearl conforms to the market economy, the price of buying and selling is very random. At the same time, there is no reference to the pricing literature of the night pearl, and the collection value is much higher than that of diamonds, so the internationally popular diamond pricing formula is selected to evaluate the value of the night pearl. Results A fluorite luminous pearl with a diameter of 4 1.8 cm and a weight of 122 g was estimated to be $7.4 billion. In the discussion, experts agreed that: now is a market economy society, the survival of the fittest, and things are rare. Recognized value is only gradually formed in market transactions. In the final analysis, the market has the final say!
Houba
According to the historical records of past dynasties, the luminous pearl was known as "luminous jade", "bright moon pearl", "hanging Li", "hanging spine", "following pearl" and "the world's mingqi" in ancient times. The reserves of fluorite with phosphorescence in the world are not large. China accounts for 35% of the world's total, mainly distributed in Zhejiang, Jiangxi, Fujian, Inner Mongolia and other places.
The appearance of the night pearl has a long history, and its cultural connotation is very rich and its knowledge is extremely profound. For thousands of years, with the passage of long years, it has been interpreted as "night pearl culture" in China. The ancient night pearl has official history, long-term history and foreign history. There are eulogies and records in novels, operas and poems. Because of its rarity, rarity and priceless value, the Night Pearl not only formed oriental culture in Southeast Asia, but also had a far-reaching influence in Europe and America through the propaganda of oriental culture in the world, and gradually merged into the gorgeous colors of western culture. Western tycoons, businessmen and celebrities are drooling over the night pearl, forming a "night pearl collection fever." In order to promote Chinese jewelry culture, we should publicize the night pearl scientifically and correctly.
In recent years, in order to make money, some people make fake and shoddy night pearls, which deceive the world and harm others. One, it messed up the jewelry market and desecrated the sanctity of the night pearl; Secondly, it destroyed Baode, Yude and Rende, the ancestors of the Chinese people, who have been handed down to future generations.
I am convinced that in the near future, the country will rectify and purify the jewelry market, so that China's "night pearl culture" will shine in the world!
Due to the different activators in activated crystalline phosphors, activated crystalline phosphors, that is, "luminous pearls", can be divided into two categories:
(1) The luminous luminous night pearl: it does not need to be excited by any external energy, but can be excited by itself by radioactive isotopes such as14c.3h.147pm.226ra.232th..
② Long-lasting luminous luminous pearl: The activator in the phosphor is not radioactive, and it can only emit light after being excited by external sunlight, ultraviolet rays and other light sources.

The Story Outline of the Night Pearl (1983)
During the summer vacation, Xiaoli came from Shanghai to visit relatives in Sangqiao Brigade, which is rich in pearls, and was welcomed by many small partners such as Tao Tao, Pingping, Xiaopaozhan, Niu Niu and Afa. However, grandma Chen, who once raised them, suddenly went blind, which made Xiaoli and the children feel very sad. The children heard that snake gall can improve eyesight, so Tao Tao took the lead and led her friends to the mountains to find snakes. On the way, Xiaoli was surprised and scared. Later, they met a big snake, and the children were afraid. Fortunately, Aunt Pearl arrived in time to avoid a possible disaster. Grandma Chen ate the snake gall sent by the children, but her eyes still didn't get better. The friends were very disappointed. I heard that eating fish can increase nutrition, so the children came to the river to catch fish and touch shrimp for grandma Chen. Tao Tao touched a big mussel from the river and found a huge pearl in it. He jumped for joy. They thought it was a huge pearl, which would definitely brighten grandma Chen's eyes. Who knows, when grandma Chen opened the box, there was no night pearl at all, but a glass marble. The children recognized that the marbles belonged to Afa and went to Afa for pearls. Afa denied it, Afa Niang was unreasonable, and the children had to leave in dismay. One day, Xiao Li read in the newspaper that the famous ophthalmologists in the provincial capital had made more than 100 patients see the light again, so she told Tao Tao excitedly. In the evening, they made an appointment with other friends and rowed to the provincial capital to find Dr. Zhong's home. Early in the morning, Dr. Zhong was deeply moved when he saw the children sleeping on the street, and decided to go with them to treat grandma Chen immediately. Afa took the "Night Pearl" by "switching bags", and he was always uneasy. He wanted to give it to Grandma Chen privately, but it fell into the goose grass basin and was swallowed by the big white goose. Afa Niang carried the white goose to sell, and Afa came to get back the big white goose and took out the pearls, but Afa got a heavy slap in the face from her mother. Dr. Zhong cured Grandma Chen's eye disease, and Afa also handed over the "pearl of the night" and admitted his mistake. Grandma Chen wants to give the "Night Pearl" to Dr. Zhong. Dr. Zhong refused to accept it. He said excitedly, "I saw the real night pearl. This is the children's hearts!" .
