Lab Grown Rough Diamonds Description
You may have heard that diamonds come from coal. In fact, it takes 3.3 billion years for diamonds to form in a specific area 90 miles below the earth's crust. This process requires a very high temperature, at least 2000 degrees Fahrenheit. Although it is impossible to accelerate the organic process of diamond formation on earth, you can copy the environment and conditions, and then accelerate the process of diamond formation. That's how synthetic diamonds are made in the laboratory. They are not synthetic diamonds because they have all the characteristics of diamonds, including chemical composition and molecular structure.
Diamonds produced in the laboratory have different names, including culture diamond, engineering diamond, synthetic diamond and synthetic diamond. Diamond planting technology was first established in 1955, when the first laboratory grown diamond in history was made. Under the same chemical composition, the laboratory grown diamonds have the same appearance and hardness as natural diamonds. However, it was not until the late 1980s that the quality of diamonds produced in the laboratory improved that the technology developed to today's level.

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.
