Historical allusions
Successive dynasties Allusion The Pearl
Night-luminescent PearlNote: according to historical records, as early as in prehistoric Yan Di The family of God has been appeared overnight pearl, as he has a stone ball king known as "night mine". The Warring States era, such as" Hang Li "And" vertical The spine of the wall ", very valuable, comparable jade. At that time, only the big authoritative Tao Gong (Van together) and valence meal (merchants during the Warring States period) two people could afford to buy. Jin had "vertical The spine of the wall "Bait" vacation and Yu to compilation". Chu, Qin, Wei's doctor had borrowed pearl moral philosophy, discuss state affairs. Qin Shihuang buries the Pearl, taking in the tomb " Paste the candle ". Han The queen Younger brother Guo Kuang "Hanging pearl and four vertical, and as a star, such as" night looking to show off their wealth. Wu Zetianci and his ERON in Pearl, Xuanzong and return to the child (Sejong) a clear beads, light room. Tang has a car, a name" Drops of water "Pearl, the price of hundreds of millions of. Song and Yuan Ming, the royal family is particularly fond of the Pearl, which Gen Gi Khan pearl, in Taiwan had been stolen, after investigation, to its origin owner. Yuan Ming had sent officials to Sri Lanka to buy Ruby Pearl and garnet pearl. The cabinet of Ming Dynasty had several blocks Emerald Pearl, the night is bright as a candle.
Luminous reason
Vast The universe Nothing is too strange., pearl, mystery, is also a eternal mystery. Since ancient times, the ancient people often with love, surprise, be very much puzzled by mood, Ye Mingzhu Indulge in elaborating on . Some ancient literature and folk tales, often to the Pearl apply a layer of a layer of mystery, invent another exciting myth. For example
Night-luminescent Pearl(6)There is a myth, legend, the "dragon pearl shines as the day......" .
According to classification
According to the material points
"Pearl" in accordance with the matrix of different materials can be divided into two categories.1Animals and plants "pearl"The animal world: such as the famous The firefly All the world knows. The Tang Dynasty Su jaw "Du Yang miscellaneous code" in Tang Dynasty, people first, Nanchang country offer "Yeming rhinoceros". The plant kingdom with luminous a lot, such as " Compendium of Materia Medica "Records of Ganoderma lucidum" beruas Xi Zhi "," Shen Cheng Zhi "," seven Jiuguang Zhi "fluorescence.
2 Mineral Gemstone pearl: from Solid state physics Angle of mineral "Pearl" of the base material is Inorganic salt Class of crystals in the activation of crystalline phosphor.
The so-called active crystalline phosphor is due to crystal lattice distortion and obtain "luminous" ability of the crystal, and this kind of distortion, and mostly due to matrix containing some Heavy metal Impurity (activator) caused by. For example, ZnS containing a small amount of the Cu Can emit yellow-green phosphor, this ZnS as matrix, Cu as activator.
According to the phosphor points
Due to the activation of crystalline phosphor in different activator can be activated amorphous phosphor is the "Pearl" is divided into two categories:1,Permanent luminous Ye Mingzhu: without excitation using any external energy, but by their own containing activator, such as 14C.3H. 147Pm.226Ra.232Th., radioactive Isotope The excitation and emission, energy.
The rare earth luminous pearl2,Long Yu Hui light-storing luminous pearl: in activator not radioactive, must rely on outside of the sun, Ultraviolet rays Light source Excitation In order to light. This common phosphor than 100 kinds, their chemical composition in addition to Alkali metal Halide, are Two price Metal (Ca, Sr, Ba, Cd, Mg, Zn) compounds -- Sulfide , selenide, telluride, Silicate , aluminate, tungstate, Phosphate And Halogen Phosphate.
Among them, Silicate And aluminates Rare earth Light storage luminous pearl because of using new Rare earth luminescent materials As the main raw material of non-toxic harmless, no radiation, environmental health, has been widely used, For example Stone imitation pearl, rare earth rare-earth luminous ball (the ball).
Natural pearls are extremely rare and rare, we identified the authenticity of it, except by gem testing instrument science were identified, also can be identified according to many characteristics which have.
The natural pearl
(1) subject to light 15 minutes, can in dozens of Hours Light grey fluorite continuous light.
The world's largest pearl(5)(2) with Phosphorescence The phenomenon, which can produce pearl quasi effect.
(3) the colour is beautiful, translucent, without any light, is permanently active luminescence, and luminescence energy larger.
(4) we must distinguish between the fluorescence and phosphorescence of fluorite, Phosphorescence In the external light source, removed after certain time can keep emitting.
(5) to observe the light length, its uniformity, and Half-life , persistence length.
Artificial pearl
(1) filled with fluorescent powder in fluorite fractured itself is not luminous, only local or linear light.(2) through the light emitting part time short, fleeting.
(3) filling illuminant, flaw clearly, there are obvious signs, visual, easy to see through.
Because of the high value of pure natural pearl, in the identification of the authenticity of, be serious, serious attitude, should have a national gem authoritative testing organizations issued a certificate of authentication as the basis.
Fluorite.
Looking at the Chinese history , Jewels Emerge in an endless stream, but the unexpected is, in the Guangzhou Jewelry wholesale market, known as the "luminous jade", "Pearl" of the products meet the eye everywhere, up to ten thousand or twenty thousand yuan, down to hundreds of yuan every.Panyu Jewelry market, the most expensive is from" Jade "Concept evolved as the wholesale price of jade, but also thousands of yuan. The reporter saw a diameter of over 5 cm, Excellent singing or polished writing The so-called "Pearl" only needs 400 yuan, the Geological Bureau Testing Center, as the Fluorite Polished. Testing Center believes that: "in ancient times, Pearl White is fluorite."
Guangdong Bureau of geology Jewelry Testing Center Director Xiang Xianbiao think, the Chinese jewelry culture includes not only the real valuable part, also inevitably have a legend and exaggeration, and exaggeration of the part is often the business use, become misleading investors, the pursuit of profit. For this problem, we need to take an objective view.
Pearl: the night can emit light automatically. According to this characteristic, Geologist That night bright pearl is fluorite is a great possibility, because in China there are ancient gem mining capacity, only the fluorite has the characteristics of light automatically absorb sunlight. The higher content of fluorite in the geological storage of, not a precious gem resources.
Historical records of the fault esker slag water on the west side of the name, this Hubei Province The central region . Geologists therefore explores, in Hubei City of Zhongxiang Found near a large number of Kimberley rock China, can produce rare diamond mine (gem diamonds), Sui Houzhu is likely to Jin Gangshi .[2]
The world
In November 21, 2010 a weighing 6 tons, 1.6 meters in diameter, the value of 2200000000 yuan in the Pearl Hainan Wenchang City Jade Palace exhibition. According to insiders, the pearl is the world's largest one, is on public display for the first time meet with the people of the world.
The world's largest pearlOn that day, more than 200 pieces of natural art, many collectors collection of natural stone free exhibition in Wenchang Jade Palace, attracted a lot of public attention.
Into the jade palace, in different poses and with different expressions stone Baoyu a superb collection of beautiful things, there are all green, sleek and smooth pearl, the morphology of likeness of the Shenzhou 1 spacecraft "Shenzhou stalactites, Chang E flying to the moon", a translucent jade "Sleeping Beauty", and the magnificent stone etc.. A natural treasure, let the audience as the acme of perfection[3].
Vice chairman of China stone jewelry Association Zheng Baoshi Said, in the hall of the most eye-catching pearl, from China Inner Mongolia , material with fluorite mineral, found to be irregular in shape, and present 3 years of processing, can send a translucent light in the light is turned off in the dark environment. Industry experts estimate the value of 2200000000 yuan.[4]
