Would you choose to buy lab-grown or natural diamonds?
Natural diamonds are a gift from nature, and cultivated diamonds are the crystallization of human wisdom. Each has its own characteristics. No matter which one you choose, you should be respected. Don’t say that diamonds are an IQ tax. Isn’t it more meaningful to buy a diamond ring for marriage? It's just that a piece of jewelry needs to constantly weigh the pros and cons, so it is completely possible not to buy diamonds, but there is no so... moreWould you choose to buy lab-grown or natural diamonds?
Natural diamonds are a gift from nature, and cultivated diamonds are the crystallization of human wisdom. Each has its own characteristics. No matter which one you choose, you should be respected. Don’t say that diamonds are an IQ tax. Isn’t it more meaningful to buy a diamond ring for marriage? It's just that a piece of jewelry needs to constantly weigh the pros and cons, so it is completely possible not to buy diamonds, but there is no souvenir.
The cost of mining natural diamonds is high, and the price is high. Some people like natural things, and they can buy them if they can reach the economic level.
Lab-grown diamonds are laboratory-grown diamonds, which are zero-carbon and environmentally friendly, and the price is low. You can buy the largest diamond with the least amount of money, and the wearing effect is better, and you like it.
Therefore, there is no need to stick to natural or cultivated, there will be people who like it, and there will be a market.

According to Shan Chongxin, a professor at Zhengda University, diamond is made of carbon element under the special conditions of high temperature and high pressure deep in the earth, plus a certain content and ratio of iron group metals as catalysts, after hundreds of millions of years of "cultivation". And artificially cultivated diamonds can shorten this time to two or three weeks, just like planting flowers and plants, "growing" it in the laboratory.
According to Shan Chongxin, a professor at Zhengda University, diamond is made of carbon element under the special conditions of high temperature and high pressure deep in the earth, plus a certain content and ratio of iron group metals as catalysts, after hundreds of millions of years of "cultivation". And artificially cultivated diamonds can shorten this time to two or three weeks, just like planting flowers and plants, "growing" it in the laboratory.
The data shows that to obtain 1 carat of natural diamonds, 250 tons of ore need to be mined. Mining natural diamonds is very damaging to the natural environment, and it seems that many "scars" have been dug out on the surface of the earth. Therefore, artificially grown diamonds are of great significance for protecting and improving the natural environment.
From a technological point of view, the current mainstream technology for artificially synthesizing single crystal diamonds is the high temperature and high pressure method. In the synthesis process of this method, nitrogen or catalysts often enter the diamond, resulting in more impurities in the artificial diamond.
"Our synthetic diamonds synthesized by chemical vapor deposition have fewer impurities than natural diamonds and synthetic diamonds synthesized by high temperature and high pressure methods, and are more suitable for optoelectronic functional applications," he said. Under the illumination of the light, the diamonds "planted" in the laboratory are shiny, clean and bright.
The pursuit of pure and pure scientific research spirit is also deeply integrated into Shan Chongxin's work and life. He often said: "Scientific research itself is a very pure job, and researchers also need a pure dedication and dedication to their original aspirations."
