In 1971, Wang Zhankui, who lives in Chifeng, Inner Mongolia, saved a Mongolian old man who was about to freeze in the snow. After Wang Zhankui took good care of himself, the old man was pulled back from the death line. On the occasion of leaving the old man, the old man gave him a small box in order to thank him for his help. Because it is very common for the Mongolians to give gifts to each other in the local area, Wang Zhankui did not care, it was a small gadget, and it was put into the pocket of his clothes. When I got home, I forgot the gift, letting it "sleep" in the pocket of my clothes. Twenty years later, I found this gift inadvertently when I was sorting out the sundries. The gift is a small box made of very fine aggregate wrapped in yellow silk satin. After the box was opened, Pharaoh took out a small ball like a mudball under the thick wax seal, which looked very inconspicuous. At that time, Pharaoh still regarded it as a very ordinary ball. However, by chance, Pharaoh found that the ball could shine in the night and was placed in the fish tank of the old king's house. In the middle of the night, it was very clear that the fish was walking in the water. It was also true and illusory. After being stimulated by the camera flash, the night can use the "small ball" light to see the writing in the book. "Is this a baby?", "Is this a night pearl?" At the suggestion of a friend, Wang Zhankui took the ball to the Tianjin Jewelry Testing Center for identification. The result is that this ball is the meteorite diamond night pearl that fell from the sky. The expert estimated more than 30 million yuan, which is happy to break Wang Zhankui. However, in less than a week, the expert declared that this certificate of authentication was invalidated. The tens of millions of night pearls turned into small mud balls that were worthless, and Wang Zhankui decided to go to Beijing to do a more comprehensive appraisal. After the detection of infrared and electron probes, the appraisers confirmed that the ball was a diamond night pearl, not artificially bonded; and finally identified this meteorite diamond night pearl that was not only the night pearl but also fell from the sky. The experts were valued at more than $25 million. In order to thoroughly understand this magical "small ball", Tianjin International Gem Testing and Appraisal Center, Geological Identification Office of China University of Geosciences, China Academy of Geological Sciences, X-ray Testing Center of China National Petroleum Corporation, China Jewelry Association Jewelry Identification and Testing Center, etc. This night pearl has been tested by electronic probe analysis, backscattered electron image analysis, X-ray diffraction analysis and infrared spectrum analysis to determine its element structure and seek its cause. The test results show that: this night pearl is mainly composed of hexagonal diamond and wurtzite, and the spherical type is naturally formed. In view of the fact that the diamond is hexagonal crystal, the six long lines appearing in combination with X-ray diffraction are compared with the international universal card and system mineralogical data. In comparison, it was finally identified that the sphere was a meteorite diamond that descended from space. The appraisal room of China Gemstone Association has carried out comprehensive testing and appraisal, and it has been named as “Gemstone Diamond Night Pearl†(also known as Liufang Diamond Night Pearl International Scientific Name Lons_sdaleite), and has issued the “Appraisal Report†and “Appraisal Certificateâ€. 》. On July 22, 2000, the Chinese Gemstone Association, the Chinese Cultural Relics Society, and the Jade Research Committee formed an expert evaluation of the meteorite diamond night pearl. The evaluation experts unanimously believe that the pearl's luminescence performance is unique and extremely rare. It is indeed a rare treasure. It provides a physical basis for the literature and mysterious legends of the Night Pearl, and has a high collection and scientific value. According to the value of international exotic treasures, it is estimated to be more than five million US dollars (25,000,000.00 USD). So what is a meteorite? Meteorite refers to the meteoroid remnant nucleus that reaches the surface after ablation from the interstellar space through the atmosphere. The shape of the meteorites varies, and the size of the individual varies. The surface of the meteorite generally has a thin (less than 1 mm) black or dark brown frit. It is the surface of the meteorite that melts during the landing in the atmosphere due to high temperature. It is cooled and solidified when lowered. The meteorites are generally divided into three categories: stone gangue, iron gangue and stone iron gangue. The meteorite is mainly composed of silicate minerals. The meteorite is a meteorite mainly composed of iron-nickel metal. The meteorite is a vermiculite with half of iron and stone. Dendrobium can be further divided into relatively primitive chondrites and differentiated aspheric gangues depending on whether or not spherulites are present. 1) Dendrobium: It is a rich type in the meteorite, similar to some rocks on the earth, but the weight of the meteorite is slightly heavier. If the meteorite is not broken for a long time, the common ordinary chondrite can be seen inside the distribution of bright silver metal iron particles, and the silicate pellets with more content can also be observed. 2) Iron meteorite: The iron meteorite is mainly composed of iron-nickel metal. It has an irregular shape and a high density. The iron meteorite is very magnetic. There are some “fingerprintâ€-like structures on the surface of some fresh iron meteorites. Below are some pictures of iron meteorites. 3) Stone iron meteorite: There are relatively few stone iron meteorites, mainly including two types: medium iron meteorite and olive iron. Olive ferroniobium is mainly composed of light green-yellow olivine crystals and iron-nickel matrix. In other words, the medium iron vermiculite is composed of massive and veined metals, and does not contain spheroidal basalt and glass matrix. What is a diamond? Diamond, the chemical composition is carbon, which is the only single element in a gemstone. Is an equiaxed crystal system. The crystal forms are mostly octahedron, rhombohedral dodecahedron, tetrahedron and their polymorphism. Pure diamonds are colorless and transparent, with different colors due to the incorporation of trace elements. Strong diamond gloss. The refractive index is 2.417 and the dispersion is medium, which is 0.044. Homogeneous body. The thermal conductivity is 0.35 cal/cm·sec·degree. Tested with a thermal conductivity meter, the reaction is sensitive. The hardness is 10, which is a hard mineral known at present. The absolute hardness is 1000 times that of quartz and 150 times that of corundum. It is afraid of heavy blows and will be chopped and broken after heavy blow. A set of cleaves is complete. The density is 3.52 g/cm 3 . Diamonds are luminescent, and after daylight, they emit a light cyan phosphorescence at night. X-ray irradiation emits sky blue fluorescence. Diamonds are chemically stable and do not readily dissolve in acids and bases at ambient temperatures, and acids and bases do not. What is the night pearl? "Night Pearl" is a natural, self-illuminating jewel in the dark that can be seen by the human eye. From the perspective of solid physics, the matrix material of the mineral "night pearl" is an activated crystalline phosphor in inorganic salt crystals. The so-called activated crystalline phosphor refers to the crystal of "lighting" ability due to 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. This ZnS is called a matrix, and Cu is called an activator. There are no less than one hundred kinds of commonly used phosphors. Their chemical composition is a compound of divalent metal (Ca.SrBa.Cd.Mg.Zn.) except for alkali metal halides - sulfide, selenide, telluride, silicon. Acid salts, aluminates, tungstates, phosphates and halogen phosphates. The activation of crystalline phosphors, or "night pearls", can be divided into two categories due to the activation of different activators in crystalline phosphors: 1 permanent luminous night pearl: no need to use any external energy to stimulate, but by itself contains an activator, such as 14C. 3H. 147Pm. 226Ra. 232Th. A radioisotope that emits light by itself. 2 long afterglow luminescent night pearl: the activator in the phosphor is not radioactive, it must be excited by the external sunlight, ultraviolet light and other light sources before it can emit light.
