Lab Grown Rough Diamonds Description
Diamonds produced in laboratories, as the name suggests, are synthetic diamonds produced in laboratories. It's the only thing that's different from their naturally occurring counterparts. Managed under strict guidelines and a highly controlled pressure environment, authorized creators replicate the exact composition of natural diamonds. Since the core of diamonds is carbon, the diamonds made in the laboratory have exactly the same chemical and physical properties, and there is no monopoly regulation in the mining industry, so they are cost-effective for consumers.
Diamonds grown in the laboratory are manufactured by advanced processes such as high pressure high temperature (hPTP) and chemical vapor deposition (CVD). When using the hPTP creation method, a small diamond seed is placed in a pure carbon form. The seeds are then exposed to temperatures above 1500 degrees Celsius and pressure of about 1.5 million pounds per square inch. The fusion of the two components forms pure carbon diamond. When CVD is used, the process is slightly different. A diamond seed is placed in a heated sealed chamber and exposed to a carbon rich gas. High temperatures of 800 degrees Celsius combine with the gas, causing the carbon to crystallize and form diamonds. These processes are merely replications of the same environment in the earth's core.

Lab Grown Rough Diamonds Introduction
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.
