Lab Grown Rough Diamonds Description

 

What are the diamonds produced in the laboratory?
These stones are not created by the power of nature as they were millions of years ago, but by works of art in which one can participate. The diamonds were produced in industrial laboratories under the guidance of talented chemists, gemologists and technologists. Their creation process is close to nature, but much faster.
Since the best method of making stone was invented in the 1970s, the stone cultivated in the laboratory has been actively used. They are used in precision engineering, electronics and, of course, beauty and fashion. It is in the case of jewelry production that the diamonds cultivated in the laboratory are really shocking. He gradually removed the natural gems from the base, because the difference was invisible to the inexperienced.
What is the name of a diamond made in a laboratory?
Here are some names of diamonds that are grown in the lab. Depending on the manufacturer, it may be called mosangite (like rare gems extracted from meteorites), a silica (if it was produced by fian, a Russian laboratory that developed the stone formula), and even Swarovski crystals, which are popular. But it is important to note that the closest diamonds to nature are only mozang stones, which are recognized as the best diamonds to grow in the laboratory.
How diamonds are made in the laboratory
High temperature and high pressure are two main rules for diamond acquisition. Naturally, they are carbon that is deeply pressed in the crust at high temperatures. After human beings have learned about the structure of a real diamond, we have tried to repeat it manually. Today, there are two main manufacturing methods. The first is high temperature and high pressure, the second is chemical vapor deposition. The two methods are both interrelated and complementary.

Lab Grown Rough Diamonds Introduction


HPHT is the abbreviation for high temperature and high pressure treatment, and its purpose is to change or improve the natural body color of certain types of diamonds to make them more valuable.


In the past, it was called Pegasus diamond and GE POL diamond. The reason why it is called GE Diamond is because The technology developed by GE in the United States is a new product exclusively sold by POL, a subsidiary of Israel's LKI, in 1999.


HPHT technology is to process natural diamonds at high temperature and high pressure to enhance the color grade of diamonds. In one move, it can be upgraded to 4-6 levels. However, not every diamond can be processed by this technology. It must have a J color or higher, and be free of impurities and high-clarity quality. During processing, the results cannot be predicted. In other words, it is not certain what level it can be promoted to.


At the same time, diamonds treated with HPHT may deepen or change in color to become a colored diamond.

 

Natural diamonds are created by nature and are the result of high temperature and pressure formed over billions of years. The Rough Lab Grown Diamonds are produced in the laboratory, usually in a few weeks. The chemical difference between the two is same.

So how do you distinguish between Rough Lab Grown Diamonds and natural diamonds?

There is no obvious difference between the Rough Lab Grown Diamonds and natural diamonds. Even professional gemologists need special equipment to identify them. By zooming in, professionals will be able to discern subtle contrasts in diamond inclusions grown and mined in the laboratory.
