I think everyone has heard of diamonds in peas, but how much do you know about diamonds? What are its functions and what value does it have? All these questions tell us that the origin of diamond is not that simple, that is to say, diamond is scarcer and more precious than ordinary natural materials.

In the era of Industry 4.0, superhard materials and products represented by diamond were hailed as “the hardest and sharpest industrial teeth”. Various difficult material processing problems in the fields of aerospace, national defense and military industry, photovoltaics and electronic information have all become minor problems. “Using the super-hard mechanical properties of diamond, all the known materials in the world can be processed.”

In the era of large consumption, diamonds are already our favorite rough diamonds. Diamonds actually refer to polished diamonds. On May 16, 2017, at the Spring Jewelry Auction held by Sotheby’s in Geneva, Switzerland, a pair of colorful pear-shaped diamond earrings set a new record in auction history at a total price of about 395 million yuan.

Today, the hardness of diamonds represents a long-term existence, and the slogan “Diamonds are forever, a forever spread” is also deeply rooted in the hearts of the people. So in modern life, due to the special quality of diamonds, we call marriages that have been married for 60 years as “diamond marriages”, and even call older girls who have been unmarried as “diamond leftovers”.

In any case, it can be seen from the above that diamonds are different from ordinary natural substances in terms of their own unique functions and substantial values. The word “diamond” itself means “invincible and indestructible” in Greek. Many peoples in the world regard diamond as their god, and respectfully call it the “king of gems.”

Having said this, have you ever thought about a question, why can diamond be used to process all other known materials? For example, the Diamond cup grinding wheel is the product of diamond processing. From this we raise a question, is there really an existence that transcends all other substances in nature? However, the question of where the diamond comes from has always plagued the entire scientific community.
