Lab-Created Rough Diamonds Description


Lab diamonds are diamonds grown in the laboratory. The diamond layer is synthesized by growing natural or artificial diamonds as seed crystals and simulates the growth environment of natural diamonds. Natural diamonds and man-made diamonds are pure carbon crystals, and their crystal structure, physical properties, chemical properties and optical properties are exactly the same.

Are the lab-created rough diamonds real diamonds? The diamond industry often uses these analogies to answer this question: lab diamonds and natural diamonds are like the relationship between greenhouse flowers and natural flowers. They are all flowers, but they grow in different environments. Lab diamonds and natural diamonds are like ice in a refrigerator and ice in nature. They are all ice, but the formation environment is different.
Synthetic diamonds, also known as laboratory grown diamonds, cultivated diamonds or cultivated diamonds. Unlike natural diamonds formed by geological processes or imitation diamonds made of non-diamond materials that are similar in appearance to diamonds, synthetic diamonds are diamonds produced through a controlled process. Synthetic diamond production methods include HPHT (high pressure and high temperature) growth method or CVD (chemical vapor deposition) method.
In the 1950s, the laboratory produced artificial diamonds suitable for industrial use for the first time. Although the laboratory produced gem-quality diamonds for the first time in 1971, it was not until the mid 2010s that colorless diamonds grown in the laboratory entered the gem and jewelry market in large numbers.

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-Created 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-Created Diamonds and natural diamonds?

There is no obvious difference between the Lab-Created 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.
