Lab Grown Rough Diamonds Description
Diamonds made in the laboratory are made in the laboratory. It starts with a small chemical called a diamond seed. It's then exposed to high temperatures, plus a carbon coating, all of which are designed to help laboratory made diamonds crystallize as they grow.
Diamonds grown in the laboratory have the same optical and chemical composition as those created by the earth. The flash point is the same - the central difference between them is their origin.
Lab produced diamonds allow you to maximize your budget, giving up more than 30% of your size at the same cost, while Earth created diamonds are works of incredible natural and traditional choice.
The diamonds grown in the laboratory have the same chemical composition and crystal structure as those produced in the earth. Synthetic diamonds (such as cubic zirconia) are made of different materials than Earth created and laboratory grown diamonds, and it's easy to distinguish between the two. The diamonds produced in the lab are real deals - they can't be distinguished from the diamonds created on earth, even with a professional loupe.

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.
