Lab grown diamonds are no longer distinguishable from natural diamonds

A long time has passed since man discovered the diamond. There is nothing more special about a diamond than its hardness. We are often under the impression that hardness is synonymous with metals, which are supposed to be considerably harder than diamonds. In reality, however, diamonds are the hardest substance in nature. We only need to do one experiment to know that if we hold a diamond in our hand, we can scratch it on most metals with just a little pressure.


This hard quality of diamonds is often of little practical use to us in our daily lives. But in industry, hard objects can often be used as drill bits for all kinds of cutting equipment. But as experts discovered that the optical properties of diamonds were just as excellent, they eventually came into view in the form of gemstones. Diamonds have a very high reflectance, a small critical angle of reflection, and a wide range of total reflection. These properties make diamonds highly susceptible to total reflection and make them appear more brilliant than other gemstones. This is why jewelers have made it possible for the octahedral diamond to sparkle and shine using exquisite cutting techniques. As a result, diamonds have become a new luxury.


Despite all of its excellent properties, the amazing thing about diamonds is that they are made up of carbon, the same element as the pencil lead we normally use. Diamonds are a world away from pencil lead simply because their physical structure is not the same. So some experts began to investigate whether there was a way to make artificial diamonds from ordinary carbon by using artificial means. Natural diamonds are created because carbon atoms have been buried under high pressure in the ground for millions of years and have been squeezed over time. So experts created artificially high temperature and pressure environments through laboratory conditions. The world's first man-made diamond was finally created in this way by General Electric in 1954.

When the technology for lab grown diamond first came out, the cost was not as high as that of natural diamonds, but it was not affordable for the general public either. So jewelers had no intention of using man-made diamonds to make diamond rings. And there were flaws in the manufacturing technology at the time, such as the fact that a small number of nitrogen atoms would still enter the experimental equipment throughout the manufacturing process, causing the man-made diamond to take on a slight yellow color. Secondly, the physical structure of a natural diamond is ortho-octahedral, whereas a man-made diamond is not, resulting in a phosphorescent phenomenon. These cosmetic flaws were a fatal drawback for jewelers, but irrelevant for industrial equipment, so the earliest man-made diamonds were mainly used for industrial purposes.


As society developed and people's living standards rose, they slowly reached a point where they could accept artificial diamonds. As a result, jewelers began to make diamond rings with synthetic diamonds. As a result of the technological advancement of man-made diamonds, the quality of man-made diamonds is now very high. From the naked eye alone, we can no longer tell whether a diamond is lab diamond or not.
