As early as more than ten years ago, some people have been proposing the theory of Lab-Grown diamonds. However, because the cost is too high, the gain outweighs the gain, and the price of diamonds has remained high. Recently, news came out from a laboratory in the UK that it successfully produced a 1-carat diamond.
A laboratory in Cardiff, England, successfully produced a 1-carat diamond in just a few days. Methane and hydrogen are mainly used in the production process.
Cardiff Laboratory researchers used a natural diamond as an embryo and put it into a vacuum experimental device. They injected methane and hydrogen heated to 3,000 degrees Celsius, causing a chemical reaction to release carbon atoms. Because natural diamonds themselves are composed of carbon atoms, the released carbon atoms will attach to the diamond and replicate according to the carbon atom crystal structure of natural diamonds. In this way, the diamond grows at a rate of 0.006 millimeters per hour, which is N times faster than the formation time of natural diamonds, which can take millions of years.
Cardiff Laboratory researchers say the artificial diamonds are purer than anything found in nature. And they are also considering market-oriented operations, and the price will generally be 15% to 20% lower than natural diamonds. Artificial diamonds avoid the damage to the natural environment caused by mining natural diamonds, but they will also have a serious impact on the natural diamond industry.
