Lab Created Diamonds Description
Synthetic diamond is a kind of polycrystalline diamond which is polymerized from diamond crystals 10 to 30 nanometers in diameter. Synthetic diamond molecular structure is not completely octahedral structure of natural diamond but a complex structure, which can produce phosphorescence.
Synthetic diamond, as the name suggests, grow diamonds in a lab. Through the use of natural or synthetic diamond as a seed crystal, Synthetic diamond layer in the simulation of natural diamond growth environment of the laboratory environment to grow. Natural diamond and synthetic diamond are pure carbon crystal, crystal structure, physical properties, chemical properties and optical properties of the two identical.
The physical, chemical and optical properties are all the same, so are lab-grown diamonds real or fake? 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. Synthetic diamond 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 time, the pressure of pure carbon material is 4.5 ~ 6*10^9Pa. When the temperature drops to 1000 ~ 1250℃, the crystal forms natural diamond. Deep inside the earth only a few places have the physical and chemical conditions of forming the diamond.
But, can now be simulated in the lab of natural diamond growing conditions, using HPHT (high temperature and high pressure) or CVD (chemical vapor deposition) technique in a few short weeks endogenous output laboratory cultivation of gem grade diamond.

Characteristics Of Lab Created Diamonds
Synthetic diamond are chemically, optically and structurally identical to mined diamonds. What does that mean?
|The Difference Between Lab Diamond And Natural Diamond|
|Attribute||Lab-Created Diamonds||Natural diamond||Distinction|
|Hardness value||90 GPA||90 GPA||No|
|Thermal conductivity||2*103 W/M/K||2*103 W/M/K||No|
|Thermal property||0.8*10-6 K||0.8*10-6 K||No|
|Light transmittance||DEEP UV TO FAR TR||DEEP UV TO FAR TR||No|
From a scientific point of view, synthetic diamond and natural diamond, where the only difference is that they are formed.
