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.
