Rough Lab Grown Diamonds Description
What is a laboratory rough diamond?
First of all, let's talk about diamonds. From a physical point of view, diamond is a carbon elemental crystal (crystal, which has a fixed shape and melting point), and its composition is the same as that of coal and graphite. However, although the coal and graphite we see in our lives are all black, diamonds are not black at all. They are transparent. This is because diamond, as a crystal, has a special energy band structure for the electrons inside. This structure determines that it will not absorb the energy of visible light, so visible light can pass through the entire diamond, making the diamond appear transparent.
Natural diamonds generally come to the surface of the earth during a volcanic eruption. At first, they were formed under the high temperature and high pressure environment deep in the earth, and then they were brought to the surface of the earth by magma. Most diamonds are formed almost as old as the age of the earth.
Lab-grown diamonds have been used in industry for more than 50 years, but in the past ten years, their quality and price have improved significantly, which means that these lab-grown diamonds can now be used in jewelry. Changing the "recipe" in the laboratory also means that the diamonds grown in these laboratories can also have different colors, including beautiful blues and pinks.
What are the advantages of developing diamonds in the laboratory?
Lab-grown diamonds can shine like natural diamonds.
Lab-grown diamonds can be mass-produced within a few weeks. As a result, laboratory-grown diamonds are much cheaper than natural diamonds of the same size and quantity.
In addition to colorless gems, laboratory-grown diamonds also provide a range of rare and expensive colors in their natural form.

Rough Lab Grown 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.
