The luminous pearl is a rare treasure, which is called "following the pearl", "hanging the pearl", "hanging the ridge" and "bright moon pearl" in ancient times, and its professional name is fluorite. It is formed by the accumulation of some luminous substances in the earth in the ore after millions of years, from the initial magma eruption to the later geological movement. Stones containing these luminescent rare elements, after processing, are what people call the night pearl, and the scientific name is fluorescent stone, which often has yellow-green, light blue, orange and other colors. When the fluorescent light shines under the white fluorescent lamp, it will emit beautiful fluorescence, which is obviously weak in the day and strong at night.

What is the 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. In ancient times, the "night pearl" was also called "night pearl" and "bright moon pearl". The famous "Night Pearl" includes Picking Pearls, Hanging Plums, Stone with Heavy Pricks, Jade with Phosphorus and so on.

The "Night Pearl" circulated among the people in our country has peculiar luminous performance, which can emit various colors of glittering and translucent brilliance in a dim environment. The "Night Pearl" is the most mysterious, rare and precious treasure in China's 5,000-year history of civilization, which is privately owned by the imperial power. The 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 comparable to that of the "Heshi Wall".

Classification of night pearl

"Night Pearl" can be divided into two categories according to the different matrix materials.

1. "Night Pearl" of animals and plants: It is well known that there are luminous people in the animal kingdom, such as the famous fireflies. Su Jaw's Duyang Miscellany in the Tang Dynasty records that in the first year, Nanchang offered 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 pearl: From the point of view of solid physics, the matrix materials of mineral luminous pearl are all active crystalline phosphors in inorganic salts.

The so-called active crystalline phosphor refers to the crystal that has the ability of "emitting light" 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 commonly used phosphors, all of which are divalent metals (Ca. Sr？ Compounds-sulfide, selenide, telluride, silicate, aluminate, tungstate, phosphate and halophosphate. "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 acceded to the throne, and princes have returned to the DPRK. As a "treasure of the town house", the night pearl once accompanied the emperor and his children and grandchildren into the palace. Therefore, in ancient times, the night pearl became a symbol of a country's supreme, supreme, supreme and respected rights and wealth. In people's traditional consciousness, the night pearl covered with a thick mysterious veil personifies the authority of the emperor; It is also as sacred and deified as heaven, earth, sun, moon and stars.

Because the night pearl is rare and shrouded in a mysterious color, the world has a very strong desire and curiosity about it. In daily life, many relatives and friends, as well as treasure lovers and collectors often 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 shallow interpretation of the mystery of the night pearl.

Rare mineral characteristics of the night pearl

In the world, there are thousands of minerals in nature, among which more than 20 minerals 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. The luminescent time of these luminescent minerals is long or short, and there are strong or weak differences. The most representative is fluorite with phosphorescence. It contains various rare elements, which are purple, pink, green, dark green and mottled. During the crystallization of fluorite minerals, a unique rare earth element enters the crystal lattice and forms its own light source "luminous center". Its Mohs hardness is 4~4.5. Its stone appearance is colorful and colorful. After processing, the small ones are beaded and the large ones are spherical. Under the thick night, the beads are like starlight, and the ball is like a bright moon spitting silver. Moreover, some high-quality fluorite phosphorescence pearls are bright and lasting, which is the legendary "night pearl".

The magical legend of night light

During the Eastern Han Dynasty, Xu Shen proposed that "the beauty of jade has five virtues." In the early Spring and Autumn Period, Guan Zhong proposed that "jade has nine virtues." At the end of the Spring and Autumn Period, Kong Qiu proposed that "jade has eleven virtues". The theory of jade virtue of various philosophers has provided a powerful spiritual pillar for our country to love, worship, give, appreciate, play, learn and hide jade for thousands of years. In view of this situation, the night pearl is the king of treasures in the gem world. In order to monopolize and monopolize this exclusive right, ordinary people dare not care about 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 lot of information about the night pearl, decorated it and packaged it, making it more fascinating and confusing. The scholar of Hong Men Hall said: "The universe has 36 days, and there are 72 demons under it, which is 108 heaven and earth. The pearl of the night gathers and breeds the bright light of the sun, moon and stars in the sky, the moisture of the wind, the rain and dew in space, the brilliance of the mountains and rivers on earth, and the brilliance of the essence, spirit, soul and god on earth. Moreover, in legend, the Night Pearl preaches that it is rare, rare, noble, gorgeous and mysterious because of its 36 colors, 72 chardonnay and 108 light. So, is there anything magical and precious in the world that can rival the night pearl?

Identification of the authenticity of the night pearl

Natural luminous pearls are extremely rare. We can not only use the scientific detection instruments of precious stones, but also identify their authenticity according to their many characteristics.

Natural night pearl

(1) bright 15 minutes later, light gray fluorite that can continuously emit light for dozens of hours.

(2) Phosphorescence can not only produce the imitation effect of the night pearl.

(3) Bright colors, translucency, permanent active luminescence without any illumination, and large light energy.

(4) It is necessary to distinguish the fluorescence and phosphorescence of fluorite. Phosphorescence is the function of external light source, which can keep a certain luminous time after removal.

(5) Observe its luminous length, uniformity, half-life and afterglow.

Artificial luminous pearl

(1) The fluorescent powder is filled in the cracks of fluorite which does not emit light, and it only emits light locally or linearly.

(2) After the light-emitting part is illuminated, the time is short and fleeting.

(3) Filled with luminescent materials, the defects are clear, there are obvious traces, and it is easy for the naked eye to see through.

Due to the high value of pure natural night pearl, we should take a serious and earnest attitude when identifying the authenticity, and have the identification certificate issued by the authoritative national gem 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 wild speculations. Natural night pearl, its rare and peculiar factors, cultural connotation factors, 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 gemstone industry will also move from a market economy to the world. The luminous pearl of the king of jewelry will also go abroad as "the pride and darling of jewelry".

On June 20, 2002, the National Gem newspaper published an article entitled "What is the value of pearls? , the price is in the imperial city! According to the report, China Gemstone Association held a special seminar on the value evaluation of the night pearl. Experts attending the meeting made authoritative argumentation speeches respectively. According to experts, among all the jewels recorded in the book The Theft of Cixi Mausoleum in Qing Dynasty, a night pearl weighs 422 yuan and 70 cents, which is about 133.4375 grams. At that time, the price was/kloc-0.08 million silver. By the first year of Guangxu, the value of the night pearl had increased tenfold. In 37 years of the Republic of China, it increased by 100 times.

In the early stage of the seminar on the evaluation of the value of the luminous pearl, an American institution issued two evaluation reports on fluorite luminous pearl, one with an evaluation value of10.30 billion US dollars and the other with an evaluation value 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 the Giant Night Pearl" in the 33rd issue of Collection magazine mentioned that a light gray gem night pearl weighing 2800g can continuously shine for 72 hours after being illuminated by 15 minutes, and it has been confirmed as the largest and most 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 of 6.5438+0.8 million USD.

In addition, the 63rd issue of Auction Collection Weekly of China Commercial Daily published "Rare Night Pearl Shines Brilliantly", and Beijing Daily published "Publicity of the World's Largest Night Pearl: 40cm in diameter, with a valuation exceeding 10 billion".

Experts once said: because the night pearl conforms to the market economy, the buying and selling prices are 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 accepted 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 1.22 g was valued at $7.4 billion. During the discussion, the experts agreed that it 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 historical records of past dynasties, the night pearl was called "luminous jade", "bright moon pearl", "hanging chestnuts", "hanging spines", "following pearls" and "Qi Ming in the world" in ancient times. There are not many reserves of phosphorescent fluorite in the world. China accounts for 35% of the world, 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 history and foreign history. There are eulogies and records in novels, operas and poems. Because of its rare, rare 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 all drooling over the night pearl, which has formed a "collection fever of night pearl". 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, deceiving the world and harming others. First, it messed up the jewelry market and desecrated the sacredness of the night pearl; Secondly, it destroyed Baode, Yude and Rende, the ancestors of China people have been passed 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 brilliantly in the world!

Due to the different activators in active crystalline phosphors, active crystalline phosphors, namely "luminous pearls", can be divided into two categories:

(1) luminous luminous pearl: it does not need any external energy excitation, but can be excited by itself as long as it contains activator, such as radioactive isotope14c.3h.147pm.226ra.232nd. ..

② Long-lasting luminous night 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.

Outline of the Story of the Night Pearl (1983)

During the summer vacation, Xiaoli came from Shanghai to visit relatives of Sangqiao Brigade, which is rich in pearls, and was welcomed by many small partners such as Tao Tao, Pingping, Trot Station, 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 their eyesight, so Tao Tao took the lead in leading her friends to the mountains to find snakes. On the way, Xiaoli was surprised and afraid. 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 given by the child, but her eyes still didn't get better. My friends are 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 to eat. Tao Tao touched a big clam shell in the river and found a big pearl in it. He jumped for joy. They think it is a huge pearl, which will definitely make grandma Chen shine. Who knows, grandma Chen opened the box and saw that there was no night pearl at all, but a glass marble. The children recognized these marbles as Afa's and went to Afa for pearls. Afa denied it, Afa Niang was unreasonable, and the children had to leave in frustration. One day, Xiao Li saw in the newspaper that the famous ophthalmologist in the provincial capital had restored the sight of more than 100 patients, 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 "changing the bag", and she was always uneasy. He wanted to give it to grandma Chen privately, but he fell into the goose grass basin and was swallowed by the big white goose. Afa Niang carried the white goose to sell, Afa came to retrieve the big white goose and take 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 "Night Pearl" and admitted her mistake. Grandma Chen wants to give the "Night Pearl" to Dr. Zhong. Dr. Zhong refuses to accept it. He said excitedly, "I saw the real night pearl." This is the heart of children! " .
