Synthetic Diamonds Description

Synthetic diamond is made up of 10 ~ 30 nm in diameter diamond crystal aggregation of polycrystalline diamond. The molecular structure of the synthetic diamond is not entirely octahedral structure of natural diamond, but a complex structure, can produce phosphor.

Artificial diamond, as the name implies, is cultivated in the laboratory., as the name suggests, are grown in a laboratory. Through the use of natural or synthetic diamond as a seed crystal, synthetic diamond layer in simulated natural diamond growth environment of the laboratory environment. Both natural diamond and artificial diamond are pure carbon crystals with identical crystal structure, physical properties, chemical properties and optical properties.

The physical, chemical and optical properties are all the same, so are lab-grown diamonds real or fake? The development of the 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. Artificial diamonds and natural diamonds are like ice in a refrigerator and ice in nature. They're both ice, but they formed in different environments.

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

But, can now be simulated natural diamond growth conditions in the laboratory, using HPHT (high temperature and high pressure) or CVD (chemical vapor deposition) technique in just a few weeks endogenous output laboratory cultivation of gem grade diamond.

From a scientific point of view, the only difference between man-made diamond and natural diamond is that they are formed.
