CVD and HPHT Lab Grown Diamonds Synthetic Lab Created Rough Diamonds With White Shade
Lab Created Rough Diamonds Description
You may have heard that diamonds come from coal. In fact, it takes 3.3 billion years for diamonds to form in a specific area 90 miles below the earth's crust. This process requires a very high temperature, at least 2000 degrees Fahrenheit. Although it is impossible to accelerate the organic process of diamond formation on earth, people now copy the environment and conditions, and then accelerate the process of diamond formation. That's how synthetic diamonds are made in the laboratory. They are real diamonds because they have all the characteristics of diamonds, including chemical composition and molecular structure.
Laboratory made diamonds have different names, including culture diamond, engineering diamond, synthetic diamond and lab created diamond. Diamond planting technology was first established in 1955, when the first laboratory grown diamond in history was made. Under the same chemical composition, the laboratory grown diamonds have the same appearance and hardness as natural diamonds. However, it was until the late 1980s that the quality of diamonds produced in the laboratory improved that the technology developed to today's level.

Lab Created 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. Professionals will be able to discern subtle contrasts in inclusions between lab grown and mined diamonds.
