In the United States and Europe after the end of World War II, all gold in the market was recovered to the US Treasury. There are not a few valuable items like gold necklaces and gold rings at the wedding, which are always not expensive and grand. So the DeBeers Group saw the business opportunity and successfully sold the diamond to the public with an slogan “adiamondisforeverâ€. “adiamondisforever†was translated as “Diamonds are long-lasting, a eternal rumorâ€. This advert has captured thousands of girls like a curse. Today, diamonds have become an indispensable token of marriage, symbolizing pure and eternal love. Diamonds are both the most precious in the world and the hardest substance in the world. It has a history of at least 4 billion years and is almost as long as the earth. Its chemical composition is mainly carbon, which burns at very high temperatures and produces carbon dioxide with little ash. It is precisely because of this beauty and purity, both hard and intangible characteristics, giving the diamonds a mysterious color. According to records, 3,000 years ago, the first diamond was discovered in the Krishna Valley of ancient India. People don’t know what it is and regard it as a mana with exorcism. Therefore, in Sanskrit, the word diamond is the meaning of thunder and lightning, in order to express the belief that diamonds are born of lightning. The ancient Greeks believed that diamonds were fragments of stars that had fallen to the earth. Some even thought that diamonds were the tears of the gods, or they were formed by the condensation of Tianshui or Tianlu. In ancient legends, diamonds were once thought to be able to avoid demons. Some people think that swallowing diamond powder can eliminate toxins and prevent madness. In the Middle Ages, Westerners believed that diamonds were invincible symbols, representing courage and masculinity. Only royal aristocrats were qualified to wear diamonds. Until the 15th century, the wedding proposal presented a diamond wedding ring to a girl to become a ceremony for the marriage contract. As a result, the traditional ring with diamonds became a western marriage contract culture. The diamond rings at that time were all inlaid with the natural crystals of diamonds, that is, diamond blanks that had not been precision cut, far less brilliant than today's finely crafted diamonds. In the 16th century, the polishing and cutting of diamonds became more and more widely used, and it began to become an indispensable token in the royal court and wedding ceremony. In 1919, Tokovsky's cut form based on the optical properties of diamonds was seen as the basis for modern diamond cutting. Diamonds of various shapes, such as squares, horse-eyes, ovals, triangles, and trapezoids, appeared one after another. In 1953, the 4C standard of diamonds was released. Quality, clarity, quality, and cut-off became the criteria for judging the level of diamonds and guiding people's consumption orientation.
