CVD Rough Diamonds Description
Diamonds represent firmness and invincible strength. For a long time, diamonds have been a symbol of power, status and wealth. In the hearts of modern people, diamonds, as a symbol of love and promise of marriage, represent eternal love and loyalty, and are an important way for both parties to express their love.
Lab-made diamonds and mined diamonds have the same chemical structure, only that the time of their formation are different. Lab-made diamonds can be mass-produced in a short time, while mined diamonds are formed from carbon element deep in the earth under high temperature and high pressure environment after billions of years.
Although synthetic diamonds are grown in laboratories, they are composed of carbon atoms, have the same physical properties and chemical composition as natural diamonds, and have higher purity, and lower price than natural diamonds.
Many people in the industry are optimistic about the market prospects of cultivating diamonds, because the laboratory production process is very environmentally friendly, without the environmental impact of traditional diamond mining, and the price is cheaper. The production cost is 30% or more lower than natural diamonds.

CVD 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.
