Synthetic HPHT Rough Diamonds Description
Lab-grown diamonds, as the name suggests, are diamonds made in a laboratory.
Many people may think that because they are grown in a laboratory, they are fake diamonds. In fact, lab diamonds just uses high technology to simulate the environment in which diamonds are formed in the earth's crust, and then accumulate carbon atoms layer by layer to form rough lab diamonds. The rough lab diamonds is no different from the original diamond dug from the ground. Yes, its physical and chemical properties are the same, and its molecular structure is the same, so there is no reason to suspect that it is a fake diamond, because no one can distinguish it with the naked eye.
High-temperature and high-pressure synthetic diamond technology originated in the 1950s, and was initially mainly used in the aviation and military industries. In the last ten years, the quality and cost of gem-quality synthetic diamond have reached the market level.
High-pressure high-temperature (HPHT) diamonds are made by simulating the high-temperature and high-pressure conditions of natural diamonds formed on the earth in the laboratory. This process can produce a unique shape of laboratory-grown diamond crystals, namely cubic octahedrons.
Synthetic diamond requires a carbon source, a high pressure of about 50 to 80 KB, and a high temperature of about 1350 degrees Celsius to 1800 degrees Celsius. In addition, a metal catalyst is also required. The most commonly used metal catalysts in synthetic production are nickel, cobalt, iron and alloys of these metals. The carbon source is melted in the metal catalyst around it until it reaches the saturation point, after which they crystallize to form synthetic diamonds.

Synthetic HPHT Rough Diamonds Introduction
Natural diamonds are created by nature and are the result of high temperature and pressure formed over billions of years. The 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 Lab Grown Diamonds and natural diamonds?
There is no obvious difference between the 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.
