The difference between diamond and gemstones: The composition of the diamond is carbon, and the composition of the gem is different according to different types.
This refers to: diamonds, rubies, sapphires, emeralds, nephrite, cashmers, gold emeralds, Topa stones, protein stones, red electrical stones, etc. Essence The diamond composition is carbon, its hardness is 10. Diamonds are the most hard-hardness and shiny ore on the planet. , Pink, red, black, gray also. Because the carbon atoms that make up diamonds are uniform, its crystals are extremely complete. This red and sapphire is also known as rigida. Its main component is alumina, which causes color differences due to different chromium, iron, and titanium. The main ingredients of emeralds are siliconic acid aluminum. The beautiful green is mainly due to chromium and pupa. The main ingredients of nephrite are calcium siliconicate and iron iron, which is a fibrous glitter crystal collection. The main ingredients of hard jade are sodium silicate aluminum, which produces in a metamorphic rock, and its shape is accumulated pebbles and giant gravel. The brown surface layer is formed due to weathering. This material: gemstone (jewel) refers to the kind of stone or mineral embedded that can be reached after pondering and polishing. This valuable ore, high hardness, high hardness, and unable to change under the action of atmosphere and chemicals. Can be used as instrument bearing, abrasives, decorations, etc. It also refers to precious stones. The gemstones are the most beautiful and valuable type of stone in the rocks. They are bright in color, crystal texture, bright luster, hard and durable, and at the same time are scarce. It is a natural mineral crystal that can make jewelry and other uses, such as diamonds, crystals, emeralds, rubies, sapphires and golden emeralds (changes to change Stone, cat eyes) green curtain stone, etc.; There are also a few of them are natural single mineral collection, such as ice color chalcedony and European. There are also a few organic materials, such as amber, pearls, corals, coal essence and ivory, as well as in gemstones in a broad sense. jade is also the beauty of stone. But it also has bright colors, hard and delicate textures, and beautiful luster after polishing. Reference materials: Baidu Encyclopedia-Gem
Vajrayana is a diamond that we often call (diamonds are commonly known as its), and it is a mineral composed of pure carbon. Vajra is the hardest material in nature, so it has many important industrial uses, such as fine grinding materials, high -hard cutting tools, various drills, and brushed molds. Vajrayana is also used as a component of many precision instruments. Vajrayana has various colors, from colorless to black. They can be transparent, translucent or opaque. Most diamonds are mostly yellow. The refractive index of diamonds is very high and the color scattered performance is also very strong. This is why diamond reflects colorful and flashing. Vajrayana will emit blue -green fluorescence under X -ray. Vajrayana is only produced in the goldenberry rock tube. Kingsley rocks are their native rocks, and diamonds in other places are moved by rivers, glaciers, etc. Vajrayana is generally granular. If diamond heated to 1000 ° C, it will slowly turn into graphite. In 1977, a villager in Changlin, Liaoshan Township, Lintong County, Shandong Province found the largest diamond (about the size of the egg yolk, the right picture) in China. The world's largest industrial diamond and gem -grade diamonds are produced in Brazil, all of which exceed 3100 carats (1 carat = 200 mg). The size of the gem -class diamond is 10 × 6.5 × 5 cm, named "Kulinnan". In the 1950s, the United States used graphite as a raw material to successfully create artificial diamonds under high temperature and high pressure. Nowadays, artificial diamonds are widely used in production and life, but it is difficult to create large particles.
diamond, also known as diamond, commonly known as "diamond". The chemical formula is C, which belongs to the same carbon quality as graphite. It is a kind of excellent physical properties such as super hard, wear -resistant, thermal sensitivity, heat transfer, semiconductor, and long distance. 8 seconds. It is accustomed to people who have been processed as diamonds, but not processed called diamonds. In our country, the name of diamond is first seen in the Buddhist scriptures. Diamonds are the hardest substances in nature. The best color is colorless, but there are special colors, such as blue, purple, golden yellow, etc. These colors of diamonds are rare and are treasures in diamonds. India is the most famous country in history. Now many famous diamonds in the world, such as the "Light Mountain", "Regent King", "Ollov" from India. The output of diamonds is very scarce. Usually the finished drill is one billionth of the mining volume, so the price is very expensive. The diamonds that are picked up are generally circular, rectangular, square, oval, heart -shaped, pear -shaped, osteropathic, etc. The heaviest diamond in the world is the "Curon" produced in South Africa in 1905. It weighs 3106.3 carats and has been grinded into 9 small diamonds. The weight of diamonds still accounts for the world's famous diamonds. Crystal structure: The crystal cells are facial cubic structures, and each crystal cell contains 2 groups of 8 C atoms.
Tracka is often yellow, brown, blue, green and pink, etc., but it is good for colorless. A total of 10 capsules in the world weighing more than 620 carats (124 grams) have found 10 capsules, the largest of which Cullinan, weighing 3106 carats (621.35 grams), a size of 5 × 6.5 × 10 cm, 1905 1905 It was discovered in the Pretmir rock pipe in South Africa. China Changlin Diamond, weighing 158.786 carats, was found in Lintong County, Shandong in 1977, listed as a world famous diamond. The main producing areas of the world's diamonds include Australia, Zael, Botswana, former Soviet Union, South Africa, Brazil, Namibia, Ghana, China Africa, Sierra Leine and China. It is the tenth category in Mo's hardness.
Attachment: The giant grains and large grain diamonds produced in my country 1971 have been discovered in China in my country. The time of time is as follows: [1] On September 25, 1971, a diamond weighing 52.71 carat was found next to Suqian Highway, Jiangsu Province. [2] On December 21, 1977, in the Changlin Brigade of Lintong County, Shandong Province, the female member Wei Zhenfang discovered a high -quality giant drill we weighed 158.786 carats. China is the most. " Named "Changlin Diamond" [3] On August 15, 1981, a 124.27 cauldron diamond was found in Chenbu, Tancheng, Shandong. Named "Chenbu No. 1". [4] In September 1982, a 96.94 carat diamond was found in Chenbu, Shandong. [5] In May 1983, a 92.86 carat diamond was found in Chenbu, Shandong. [6] On November 14, 1983, a giant diamond was found in Mengyin, Shandong, and was named "Mengshan One".
According to 1987, China's major diamond -forming mining areas include: ① Liaodong -Jinan Mining Area. ② Luxi, northern Jiangsu, and northern Anhui became a mining area. There may be many periods of Jinbieliyan in the ancient times. ③ Jin, Yu, and Jicheng mining areas have issued cash Berliestan in Taihang Mountain, Songshan, Wutai Mountain and other places. ④ Hunan, Guizhou, Hubei, and Chuancheng Mining Area have found 4 industrial valuable diamond sand mines in the Lishui Basin, Hunan.
It Hunan diamonds, produced in Hunan Province, Hunan Province, Hunan Province, Taoyuan, Qianyang and other places. Hunan diamonds are mainly sand ore, mainly distributed in the Lishui Basin, with scattered distribution and low quality, but the quality is good, and about 40 % of gem -grade diamonds. According to legend, during the Ming Dynasty, there were sporadic diamonds in the Qijiang Basin of Hunan, and large -scale mining began in the 1950s. The entire waters of Qijiang are distributed by diamonds, but only 4 are in Changde Dingjiagang, Taoyuan County, Taoyuan County, Xunpu County (Qianyang) Xinzhuangzhuang, and Qiling County. The color of Hunan diamonds has different shades, and the color differences in the inside and outside are obvious. Its brown series diamond, the crystal is yellow -brown, the interior is clean, and the surface has a large amount of brown spots. The color of the brown spots is yellow, yellow -brown, brown, black, etc. It is mainly distributed on the dissolved surface of diamond. The brown is mainly radioactive by nature. Graval radiation is caused. The overall granules of diamonds are small, but the texture is better. It is mainly single crystal, accounting for about 98%of the total output; the crystals are relatively complete, with eight -facial body, duodang body, and six eight facial sides; It is yellow, brown, etc.; The particle weight is more than 28mg, generally 10.9-15 mg; the 22%crystal contains a parcel; 60%of the surface of the crystal has cracks, and the surface dissolution is not heavy.

Vajrayana is the hardest material of the many natural existences found on the earth. At the same time, diamonds are not produced only on the earth. It is now found in the meteorites that have been found in the celestial body. Vajrayana is very wide, such as cutting tools in crafts and industry.nHope can help younQuestion I don't agreenAnswer what do you don’t agree withnMore 2nBleak
Diamond is a natural mineral, it is also a medium -blocking gemstone. After careful consideration, the colorless transparent vermiculite is a good substitute for diamonds. The discount rate of diamonds is nearly 2, and the color scattered is similar to the diamond. Therefore, from the appearance point of view, the diamond will also flash with colorful light, which is very similar to the diamond. The diamond has a strong double refraction, that is, it has two discounts, and the difference between the two discount rates is large. As a result, a very special optical phenomenon is generated. When observing the finished vermiculite with a magnifying glass, it can be seen from its top surface that the surface and ridgeline at the bottom are obvious. Because diamonds are "homogeneous body", there will never be a dual image phenomenon. Extension information: has a lot of gems, and there are many types of gems. I do n’t introduce them one by one, just give enthusiasts some more easy -to -understand concepts. Gemstones in a broad sense are exactly the raw materials that are suitable for pondering and carving into exquisite jewelry and crafts. Involved in two categories of beads and treasures. Including two categories: inorganic gems and organic gems. The narrow concepts: Gorgeous, transparent, flawless, high hardness, stable chemical properties, or a little transparency, but a special optical effect, a single mineral crystal with a particle size of more than 3mm or more is called gemstone. The level of diamonds is based on the 4C standard of the diamond (weight cact, color color, clarity class, cut CCUT), weight: the weight of diamond is the four major factors that affect the value of diamond value, the most important and most important factors One of the factors of the foundation is that the more the diamonds that weigh, the less the value, so the value will be raised with its rareness. The weight of the diamond is in carats, and one carat = 100 points = 0.2 grams.
What is diamond: This is the reputation of "the king of gems", which is the most precious person in high -end gems. Since in Western countries, the rough stone of diamonds is classified and valued by the central unified sales agency (CSO) located near the London Trade Center, and then the organization controls its sales. Therefore, unlike other gems, internationally, internationally, Gem diamonds have a relatively uniform hierarchical system, so it is independent of other gems. The mineral name of the diamond is diamond, and its English name is Diamond, which is derived from the Greek Adamas, which means the hardest thing. Humans have a long history of using diamonds. As early as in ancient times, people believed that diamonds had magical power, so wearing it became the most brave and strong symbol. The people of many countries use diamond rings as token of marriage and marriage, and believe it can bring happiness. The international gem industry generally sets diamonds as April birthstone, which is a symbol of pure and flawless. In ancient times, diamonds were symbols of power status. Some famous diamonds, Kulinani Ⅰ, were inlaid on the wands of the British Empire King to show that the British king enjoys supreme power in the world.
In the past century, after the gemstone entered the folk from the palace and the temple, diamond jewelry has also become a precious decoration that people yearn for. In Japan, nearly half of citizens like to buy diamond jewelry, and in the United States, about two -thirds of married women love diamonds. It is generally believed that wearing diamond jewelry can give people a spiritual beauty, which is considered a sign of material civilization. In addition, diamonds are a high -end gemstone, so it has high commercial value. Because the price of high -end gems has continued to rise and stable in the past years, the trend of high -end gems such as diamonds in the world has become increasingly obvious. In our country, diamonds are commonly known as diamonds, also known as diamonds. Due to the colorful color, dazzling brilliance, and transparentness, high -quality diamonds weigh more than 0.25 carats are regarded as gems. To distinguish it from the average diamond phase, people who can use gemstones are called gem diamonds. However, diamonds are mineral names, and diamonds are gem science names. Therefore, strictly speaking, diamonds should be a diamond gem that made into jewelry, and diamonds that have not been processed gem value are called gem diamonds. However, because most people have called diamonds as habits. Therefore, people also mixed diamonds with diamonds. diamond (scientific name), also known as diamond, diamond, English is Diamond, which originated from ancient Greek adamant, which means hard and inviolable substances. Vajrayana is very hard. The hardness here refers to the hardness (non -resistance) of the Mo family (non -resistance). The hardness is 10. It is currently known as the hardest mineral. The absolute hardness is 1,000 times the quartz and 150 times the correction. After the blow, it will be broken. Its density is 3.52 grams/cubic centimeter, d = 3.2. Qiang King Kong luster. The discount rate is high: 2.417, the color scattered is medium, 0.044. Betal body. The melting point is higher than 3550 ° C, and the boiling point is 4827 ° C. The thermal guidance rate is 0.35 calories/cm · second · degree. Test it with a hot guide, the most sensitive response. A group of explanations are complete. Diamonds are luminous. After sunlight, light green phosphorus light can be emitted at night. X -ray irradiation, emitting sky blue fluorescence. The chemical properties of diamonds are very stable, and it is not easily dissolved in acid and alkali at room temperature, and acid and alkali will not have effect on it.
