Autumn jewellery auctions around the world took turns, and the price of colored diamonds hit new highs. In recent years, the price of colored diamonds has soared, and it has always been the darling of the major diamond auctions. Even during the economic downturn, high prices can still be achieved. These reasons include the international influence of the auction house, the rarity of top gems, and the growing number of private buyers going to the auction.
So, what is a colored diamond? How is the color diamond formed?
Usually, the diamond is transparent, but the colored diamond is a diamond other than transparency. The world's colored diamonds, also known as colored diamonds, are mainly caused by the changes in the particles in the colorless diamonds. Different colors produce different colors, so the rarer the color, the higher the value. The color of the colored diamonds is more common in gold, brown, and green. Others such as pink, red, and blue are rare. They are often inaccessible, such as the blue Hope diamond (hope blue diamond). The rare treasures, of course, the value is not cheap. High-quality pink diamonds are also considered rare, and Australia is the only fixed source of pink diamonds worldwide.

The reason why diamonds present different colors is because diamonds contain different chemical trace elements and internal crystal structure deformation during the formation process. The following is a list of the reasons for the color of different colored diamonds:
Yellow diamond: light yellow, golden yellow. During the formation of a diamond, when a nitrogen atom replaces some of the carbon atoms in the diamond crystal (one hundred of each million carbon atoms are replaced), it begins to absorb blue and purple light, thus making the diamond yellow.
Blue diamond: light blue, brilliant blue. During the formation of the diamond, the trace of boron is absorbed, and the diamond is blue-blue.
Red diamond: pink, red. During the formation of the diamond, the lattice structure is distorted and the diamond is red.
Green diamond: light green, bright green. The reason for the formation of green diamonds is the change in lattice structure caused by natural radiation.
Black Diamond: The cause of color formation is caused by the inclusion of dark inclusions.

The world of diamonds is not only a single color, but also a colorful color. Like a white diamond, the price of a one-carat color diamond is also calculated based on the quality grade of the color diamond. Regarding the color diamonds, there are also detailed grades. The grades of the colored diamonds are also strictly in accordance with the color of the colored diamonds, the color of the colored diamonds, the clarity of the colored diamonds, and the cutting of the colored diamonds. The difference is that the most important criterion affecting the price of colored diamonds is color grading. The more colored the color diamond in the color diamond, the higher the value of the colored diamond. It is rarer and more precious than white, which makes it extraordinary charm.
