Artificial diamonds and some advancements of the jeweler industry

After 60 years of formation and development, the diamond culture technique in the laboratory has achieved many breakthroughs, almost able to simulate nature to create perfect diamonds. Please tell us some of the highlights of the artificial diamond industry as well as the advanced technology in today's jewelry industry.

Previously, artificial diamond developers claim that their products are of high quality, non-conflict and usually cheaper than old-style diamonds that are made in the mantle of the shell. Earth with extremely high temperatures and pressures in time, then exploited by humans. However, some gem experts disagree with this view and argue that diamond mining will contribute to promoting local economic development, while artificial diamonds are not much cheaper. with natural diamonds.

Diamond crystals are cultured by high temperature pressure technique.

However, the synthetic diamond manufacturing industry is still a scientific feat formed 60 years ago and has been continuously improved over time. The first artificial diamond created by General Electric in 1954 by high temperature and pressure technology (HPHT) simulated how natural diamonds were formed. However, diamonds created with CHT are often blurred and error-prone, thus forming a limit for the artificial diamond industry.

But that was the story of many years ago and now, most high-quality artificial diamonds are made by chemical deposition evaporation (CVD) . Completely different from the natural process, this technique produces diamonds from a mixture of hot hydrogen and hydrocarbons, adding methane at the extreme pressure tower in a vacuum chamber. The first diamond created with CVD technology was very small in size, but in the 1980s, scientists found a way to use CVD to produce diamond films.

Diamonds are made up of CVD techniques.

By the 1990s, they finally discovered a method to use CVD to create gem-quality diamonds. One of the keys to this success is to use a diamond crystal as a seed to develop a complete diamond. Scientists said recently that silicon was used to grow diamond crystals by CVD technique.The reason is that silicon has a larger atomic size than carbon and this difference leads to diamond formation.

Another factor in the breakthrough of the above technique is that it is possible to find the optimal mixture of gas and temperature to form the quality of synthetic diamonds. Currently, the CVD process has been able to cultivate 4 carat diamonds with extremely high transparency. Wuyi Wang, director of research and development at the American Gem Institute, said that the CVD diamond consumption market is growing rapidly. He said that Gemesis is one of the world's largest suppliers of synthetic diamonds and has achieved 350,000 carats in 2014 and 400,000 carats in 2015.

A rough diamond is made by CVD technique.

Wang said: "If diamonds are grown at 30 microns per hour, you need 100 hours to make 1 carat but you can grow 50 or 100 tablets at a time." However, the CVD diamond production process will quickly become obsolete. Ironically, five years ago, people returned to complete HPHT to create diamonds at a low price and at a higher quality than CVD.

Professor Wang said: "The largest crystalline tablet ever produced alf 30 carats in raw or 10.02 carat after polishing and the wire is also the largest artificial diamond in the world today. I have heard a 60 carat diamonds and a group of researchers also want to push that number to 100 carats, which will change the world diamond market completely. "

In a ring or pendant, not only artificial diamonds but also many other features are high-tech products. Currently, people also use computer software to build 3D models of rings or other types of jewelry. In this way, jewelers can easily determine the size, color and shape of the ring as well as the stone before real life. Even, the software can simulate the sparkling effect of the stone.

Images of jewelry products are built using 3D software on computers before processing in real life.

Mike Magee, senior manager of the American Gem Institute, said: "The jewelers have started using 3D rendering software on CAD computers since the mid-1990s but it hasn't been released until the 2000s. Currently CAD software for jewelry industry is highly complex and most major jewelers develop expansion packs for this software, before each CAD has been created, each design is made by hand. wax and any change will force them to start again, but in CAD, the design becomes much simpler. "

Not only does 3D modeling of jewelry on computers but now people also use 3D printing technology. After completing the design, people can use 3D printers to create a prototype for customers to see before creating the final version with real materials. Not only that, people also use lasers to heat metal powder during jewelry making. However, this technique is still expensive and there are not many jewelers applied. And in fact, people still play a major role in jewelry making, including cutting, grinding, polishing, punching and installing diamonds.

People also use lasers to heat metal powder during jewelry making.

The above are just a few information about the technology of artificial diamonds and modern jewelry techniques. The jeweler industry seems to be full of mysteries and delays compared to other industries, and it also turns out to quickly apply high technologies from many other industries to simplify the production process and create artworks. Art attached to each person's life.

If the ring proposed 10 years ago and now is no different in appearance but really, inside it contains many differences in the whole process. Hopefully after I give the ring, "tell the truth" to the girlfriend that is an artificial diamond and tell the story above, she will be happy to receive it as a product of scientific and technological progress. nowadays.
