Lab Created Diamonds Description


Lab grown Rough diamonds, as the name implies, is the growth of the diamonds in the laboratory. By using natural or artificial diamonds as seed crystals, the synthetic diamond layer is grown in a laboratory environment that mimics the conditions in which natural diamonds are grown. . Natural diamond and synthetic diamond are pure carbon crystal, crystal structure, physical properties, chemical properties and optical properties of the two identical.

Physical, chemical and optical properties is the same, so the laboratory cultivation of diamond is real or fake? Develop these diamond industry often use analogy to answer this question: laboratory breeding of diamond and natural diamond like greenhouse flowers and natural flowers. They are both flowers, but they grow in different environments. Lab-grown diamonds and natural diamonds are like ice in a refrigerator and ice in nature. They are all ice, but formed in the different environments.

Natural diamonds take millions of years to form. Before the eruption, due to the crater is often blocked, Wells from about 150 to 200 kilometers deep in the earth's crust molten magma can cool down slowly in the crater of the volcano. At this point, the pressure of pure carbon material is 4.5 ~ 6*10^9Pa. When the temperature dropped to 1000 ~ 1250 ℃, the crystallization and form a natural diamond. Only a few places deep in the Earth have the physical and chemical conditions to form diamonds.

But the growing conditions that produce natural diamonds in nature can now be simulated in the laboratory, using HPHT (high temperature and pressure) or CVD (chemical vapor deposition) techniques to produce gem-grade lab grown diamonds in just a few weeks.

From a scientific point of view, synthetic diamonds are exactly the same as natural diamonds, the only difference being where they are formed.
