It possesses a beautiful transparentness and hardness that no other gemstone can match. With the influence on many industries: jewelry, industry &#8230; Gold is increasingly proving its importance. So do you know how\u00a0<strong>diamonds are created<\/strong>\u00a0or not? Let&#8217;s find the answer with the article below!<\/p>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\"><strong>How are diamonds made?<\/strong><\/h2>\r\n\r\n\r\n\r\n<p>The sparkling diamonds are made up of minerals that contain carbon, under high temperatures and very high pressures. On earth, anywhere can produce diamonds. Because at a certain depth, there will be a temperature high enough and the pressure is large enough to form a diamond.<\/p>\r\n\r\n\r\n\r\n<p>The process of diamond formation begins at a depth of about 100 miles underground where high temperatures and pressures have crystallized carbon into rough diamonds. In continents, diamonds begin to form at depths of about 150 kilometers (90 miles), where the pressure is about 5 gigapascal and the temperature is about 1200 degrees Celsius (2200 degrees Fahrenheit).<\/p>\r\n\r\n\r\n\r\n<ul class=\"wp-block-list\">\r\n<li><strong><a href=\"https:\/\/caodiamond.com\/kim-cuong-tam\/\">Diamond Plate<\/a><\/strong><\/li>\r\n<li><strong><a href=\"https:\/\/caodiamond.com\/san-pham\/trang-suc-kim-cuong\/\">Diamond jewelry<\/a><\/strong><\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n<div class=\"wp-block-image\">\r\n<figure class=\"aligncenter\"><img decoding=\"async\" class=\"wp-image-6361\" title=\"Kim c\u01b0\u01a1ng \u0111\u01b0\u1ee3c t\u1ea1o ra nh\u01b0 th\u1ebf n\u00e0o\" src=\"https:\/\/caodiamond.com\/wp-content\/uploads\/2020\/09\/1-1492061613306.jpg\" alt=\"\" \/><\/figure>\r\n<\/div>\r\n\r\n\r\n\r\n<p>In the ocean, this process takes place in deeper areas because the temperature needs to be higher, so the pressure must also be high. As the pressures and temperatures gradually decrease, the diamond also has a larger size.<\/p>\r\n\r\n\r\n\r\n<p>When a volcano erupts (potassium volcanic rock eruption type), diamonds are brought to the ground. The last time a volcano erupted of this kind occurred about 100 million years ago, here&#8217;s an image of potassium volcanic rock.<\/p>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\"><strong>Diamond mining process<\/strong><\/h2>\r\n\r\n\r\n\r\n<p>Geologists often use termites to reach kimberlite tubes because termites when building their nests often dig for rocks and minerals, near which diamonds are often found. Kimberlite is present in the Earth&#8217;s crust, in vertical structures such as kimberlite tubes. Kimberlite pipes are the most important source of diamonds mined today.<\/p>\r\n\r\n\r\n\r\n<p>To reach the bottom of the kimberlite tube, one has to extract all the rock above, the pit-mining operation begins. Open-pit mining is the most common way in diamond mining. Heavy machinery, hydraulic excavators, trucks are used to extract diamonds from kimberlite pipes.<\/p>\r\n\r\n\r\n\r\n<div class=\"wp-block-image\">\r\n<figure class=\"aligncenter\"><img decoding=\"async\" class=\"wp-image-6359\" title=\"Kim c\u01b0\u01a1ng \u0111\u01b0\u1ee3c t\u1ea1o ra nh\u01b0 th\u1ebf n\u00e0o\" src=\"https:\/\/caodiamond.com\/wp-content\/uploads\/2020\/09\/kim-cuong-la-gi-y-nghia-kim-cuong-trong-lam-an-phong-thuy-5.jpg\" alt=\"\" \/><\/figure>\r\n<\/div>\r\n\r\n\r\n\r\n<p>It is common to open-air mining when it is predicted that diamonds will be near the surface or covered with thin layers of sand and gravel.<\/p>\r\n\r\n\r\n\r\n<p>In diamond mining, underground mining is the most complex. This type of mining method will be used based on calculations of the nature, shape and size of the kimberlite warehouse.<\/p>\r\n\r\n\r\n\r\n<p>Diamonds can also be mined from the seabed by maritime mining (horizontal and vertical extraction). The most successful business in finding profits from the seabed today is probably DeBeers, which accounts for 40% of the worldwide diamond market. As one of the pioneers in the shift from land-based mining to ocean floor mining, De Beers was also the first to develop a technology suitable for digging and collecting diamond ore at a depth of 150 meters below the surface.<\/p>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\"><strong>Chemical formula of diamonds<\/strong><\/h2>\r\n\r\n\r\n\r\n<p>The chemical formula of diamonds is made up of carbon atoms (C). In nature the C atoms for diamond formation are present in plants and carbonates. When buried in geological layers, they turn coal, peat, coal, graphite&#8230; When the environment meets conditions such as high temperature, pressure. Then the carbon will be compressed together will form diamonds in the cube crystal system.<\/p>\r\n\r\n\r\n\r\n<p>The chemical formula of diamonds is made up of carbon atoms (C).<\/p>\r\n\r\n\r\n\r\n<figure class=\"wp-block-image\"><img decoding=\"async\" class=\"wp-image-6360\" title=\"Kim c\u01b0\u01a1ng \u0111\u01b0\u1ee3c t\u1ea1o ra nh\u01b0 th\u1ebf n\u00e0o\" src=\"https:\/\/caodiamond.com\/wp-content\/uploads\/2020\/09\/Diamond_and_graphite2.jpg\" alt=\"\" \/><\/figure>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\"><strong>Diamond Crystal Structure<\/strong><\/h2>\r\n\r\n\r\n\r\n<p>Diamond crystals have a cube structure so they are highly symmetrical and contain quads carbon atoms. Each C atom will bind to the other four C atoms that are closest. Diamonds have a lot of properties.<\/p>\r\n\r\n\r\n\r\n<p>Due to the relatively high density of atoms, the rock has a very tight structure, along with a hardness of up to 10 Mohs. Hardness is at the top of both natural and man-made gemstones.<\/p>\r\n","protected":false},"excerpt":{"rendered":"<p>Kim c\u01b0\u01a1ng l\u00e0 lo\u1ea1i \u0111\u00e1 qu\u00fd \u0111\u01b0\u1ee3c s\u0103n \u0111\u00f3n nh\u1ea5t h\u00e0nh tinh.
