The past and present of diamonds?
The land of Pangu was 4 billion years ago. It was a supercontinent. The mainland has not yet split into five continents. The living matter is only organic compounds that exist in the Earth itself or in the outer space. Simple elements such as amino acids, phosphoric acid, and nucleotides. Nitrogen, carbohydrate protein primitive microorganisms, existed in unknown factors, and later evolved into advanced life.
The past and present of diamonds
Some rare carbon atoms are subjected to an excess of 2800 ° C in an anoxic state and a pressure of 1.5 million pounds per square inch in an anoxic state at a depth of 150 to 200 km. Under the extreme pressure of the earth's crust, the carbon atoms are tightly aggregated to form a colorless tetravalent bond. The regular octahedral equiaxed crystal structure, named diamond (diamond), is the crystallization of nature and time. Hundreds of millions of years in the lower mantle of 670 kilometers or more deeply, and then experienced the change of the earth's heart and was led out of the ground by the lava eruption of the mantle, with the gravel scattered in the earth's young stratum or bare. Downstream river bed.
Diamond (diamond) is the most amazing masterpiece of nature. It has the simplest composition. It is the hardest material on the earth. It has high toughness and high refractive index. The refractive index is 2.42. It is basically transparent and colorless. Other colors are: yellow. Brown, blue, green, pink and the only three blood red in the world.
Cutting and honing a diamond with a diamond-coated turntable to grind the diamonds to each other, the diamond grinding disc is gradually changed from coarse particles to fine diamond polishing powder, and finally a crystal clear, dazzling diamond is born.
Diamond, the oldest gem in the world. Every diamond comes from the heart of the earth, and on the five continents of the earth, the meteorites from the outer space also have its traces.
Everyone who has been in contact with each other is different. The cutters learn from the shape and texture of the original stone. The finished products are generally round, oval, pear-shaped, emerald-shaped, and pillow-shaped. Each one has its own uniqueness. Style, temperament. With its own cutting, each facet is intertwined with a mirror that reflects the colorful light.
