Rough Lab Grown Diamonds Description


The lab grown diamonds uses advanced technology to simulate the formation conditions of natural diamonds under the earth's crust. This formation process is the main factor that distinguishes laboratory diamonds from natural diamonds. The physical and chemical properties of laboratory-grown diamonds and natural diamonds are exactly the same as those of natural diamonds. Is there any difference between laboratory-grown diamonds and natural diamonds?
We can distinguish from the angle of formation method, price and appearance quality.
The first is the formation conditions. Natural diamonds are composed of carbon atoms and are formed after billions of years of extreme high temperature and pressure deep underground, while laboratory-grown diamonds are grown in the laboratory using equipment through a chemical process. There are two main production processes for cultivating diamonds in the laboratory, one is the high temperature and high pressure method, and the other is the chemical vapor deposition method.
The second is the price difference. Every natural diamond is unique, and the rarity of diamonds determines the high price of nature diamonds. Lab-grown diamonds can be mass-produced, so the price is cheaper than natural diamonds. 
The third is appearance quality. Natural diamonds are formed according to the natural environment, so their quality cannot be controlled. The quality of cultivated diamonds can be controlled artificially by the growth process. With the continuous advancement of technology, the quality of laboratory-grown diamonds is getting better and better.
From the above three aspects, we can understand the difference between natural diamonds and laboratory-grown diamonds. Laboratory-grown diamonds undoubtedly provide a choice for people who like to wear diamond jewelry. Because laboratory-grown diamonds and natural diamonds both are real diamonds.

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.
