“Plant” the diamond

The dazzling diamond jewelry is amazing, but the unattainable price makes people stop it. Someone thought, “It would be great if diamonds could be grown like vegetables!”

This seemingly absurd idea has now become a reality. Recently, the Ningbo Institute of Materials Science and Technology of the Chinese Academy of Sciences announced a news that is similar to the fantasy that diamonds can be “planted”! The “planted” diamond is not only comparable to natural diamonds, but the price is only one-sixth of its price. Are you eager to know how diamonds are “planted”?

The reason is simple. Planting crops requires seeds, and so does “planting” diamonds. We must first obtain “seeds”-natural diamond seed chips. With “seeds”, you can plant seeds. The difference is that “planting” diamonds does not require land and can be done in the laboratory. The nutrient needed for diamond “growth” is methane gas. Under the action of energy, methane is decomposed to form a carbon plasma. They are suspended in the air like snowflakes, and then slowly fall, gradually, layer by layer. Above the diamond “seed”. Repeatedly, the “seeds” continue to “grow up”, just like the snowmen we build in the fields on a snowy day, getting bigger and bigger. Diamonds “grow happily” in the laboratory at a speed of about 0.007 millimeters per hour. In just one week, we can harvest a one-carat diamond. The formation of a natural diamond is an extremely long process, about hundreds of millions or even billions of years.

Li He, deputy director of the Key Laboratory of Marine New Materials and Applied Technology of the Chinese Academy of Sciences, who completed the invention, said: “The diamonds grown are no different from natural diamonds in chemical composition. They are all made of carbon. Because natural diamonds Impurities are mixed in during the long-term formation process, so the purity is lower, and synthetic diamonds are better in this respect.”

The diamonds “planted” in the laboratory can not only be made into high-quality and inexpensive jewelry, but more importantly, it can be widely used in semiconductors, electricity, optics, and thermals, such as using it to make precision lasers and radars. Instruments etc.

Natural diamonds are expensive and can only become luxury items for the nobles. In fact, they are only a matter of “rarity is precious”. As the “planting” diamond technology matures and its output increases, I believe it will also “fly” into the homes of ordinary people.
