How far is we growing 4 million carat diamonds a year?

Science Fiction Network, September 15 (Wang Xiuxia) Recently, the news of 4 million carat diamonds in the small county has appeared on the hot search. Many people are curious, can diamonds be planted? Can the planting diamonds comparable to natural diamonds? Today, let's walk into the world of diamonds together.

Diamonds are actually a crystal composed of carbon elements that can be formed from high pressure and high temperature conditions of the earth, or artificial synthesis. Diamonds are often regarded as a symbol of love and loyalty due to beauty and rareness.

In 1886, South Africa discovered a diamond mine with rich reserves. Two years later, the British set up Daibish United Mining Co., Ltd. And gradually expand. During the heyday, Daibels controlled more than 85%of natural diamond production around the world. We are familiar with the advertisement of "diamonds for a long time, a forever spread", which comes from the company.

The largest natural diamond in the world, known as African Star or Kulinan, was discovered in South Africa in 1905. It has an excellent texture, no flaws, and a pale blue tone, which is the best in diamonds. Due to the large volume, it is also divided into several pieces for processing. On the scepter of the British king, the crown of the Queen of Britain and the queen of Mary, there are inlaid stones.

Compared with the long history of natural diamonds, the cultivation of diamonds appears relatively late.

The first artificial diamond was only created by a US company in 1956. In 1963, China's first artificial diamond was born. However, early artificial diamonds were used in the industrial field, and it was not enough to meet the requirements of gemstones in terms of color and clarity.

Around 2016, China used a high -temperature and high -pressure method to produce colorless particles to cultivate diamonds, and it began to try sales in the business field.

Diamonds can also be planted like food. First of all, we must have a natural diamond seed chip to use methane gas as nutrients. Under the action of energy, carbon plasma can be formed. Then, the plasma like dust can slowly precipitate in the air and attach it to the seed chip. After the week, diamonds continue to "grow up." In the laboratory environment, diamonds can grow 0.007 mm per hour. About a week, a 1 -carat -size diamond can be "harvested". The hardness and purity of the planting diamonds are comparable to natural diamonds, but the price is lower than natural diamonds.

Industry insiders said that the cultivation of diamonds and natural diamonds, just like the ice in the river and the ice in the refrigerator, the naked eye cannot see the difference, and can only be distinguished under specific instruments. " Whether we can achieve "diamond freedom" can only be given the answer.
