Lab Grown Rough Diamonds Description
At first glance, you may believe that the diamonds made in the laboratory are simulated diamonds. In fact, they are 100% real because they are chemically and structurally identical to the diamonds mined by the earth. In fact, any jeweler can use the technology they have, and it will tell them that the diamonds produced in the laboratory are real.
Diamond mimics are "synthetic diamonds" that look like them, but can offer a lower price point. Some of the main diamond mimics include cubic zirconia and carborundum. Although they all have a clear crystal appearance, the properties of diamond mimics are very different from diamonds. Unlike diamonds, these crystals are not carbon based, and you don't need any equipment to see the difference. Because colored diamonds are very rare in nature, it is easy to mistake laboratory grown colored diamonds for cubic zirconia or morsonite.

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.

Carat 1
The size of a diamond is proportional to its carat weight. When rough diamonds are cut and polished into finished diamonds, up to 2/3 of the total carat weight may be lost. Since larger rough gems of high quality are found less frequently than smaller rough gems of high quality, a single two carat diamond will be more expensive than two one-carat diamonds of the same quality.
Color H
A diamond’s color is an important element of its quality. In a white diamond, the less body color present, the greater the value of the diamond. The GIA grades diamonds on a scale of D (colorless) to Z (noticeable color).
The predominant color you see in a diamond is yellow, which is caused by the trace element nitrogen.
Clarity SI1
Clarity refers to the presence of imperfections, flaws and blemishes inside or on the surface of a diamond.
The GIA grades diamond clarity under 10X magnification on a scale that ranges from Flawless (FL) to I2-3 (Included). Diamonds with the least amount of flaws having the highest clarity grading.
A diamond’s clarity has a significant impact on its value.
Cut Very Good
The cut of a diamond influences how effectively it reflects light. Well-cut diamonds appear fiery and brilliant and allow light to enter the stone and be reflected around the facets before exiting the stone through the top. Poorly-cut diamonds can appear lifeless and dark, despite their clarity or color grade.
Not only do well-cut diamonds appear more brilliant, they also tend to appear larger than other diamonds of the same carat weight.
