0.5-4ct Fancy Cut Lab Grown Loose Diamonds For Diamonds Jewelry
Lab Grown Loose Diamonds Description
Lab diamonds are diamonds that are grown in a lab using a machine.
Lab-grown diamonds are polished and cut to be indistinguishable
from natural diamonds. Laboratory production of diamond and natural
diamond is a real diamond. The main chemical component of
lab-produced and natural diamonds is carbon.
At present, the high temperature and high pressure method and the
chemical vapor deposition method is two main methods of diamond
preparation laboratory.
Laboratory diamond forming machine can produce laboratory diamond
through high temperature, high pressure and CVD technology.
However, due to high temperature and high pressure, and chemical
vapor deposition of diamond production machine and technology,
people can be high temperature and high pressure, and chemical
vapor deposition diamond with lab.
Basically, synthetic diamond and natural diamond and natural
diamond has essentially the same physical properties, chemical
composition and crystal structure. But it cannot be called a fake
diamond, diamond on the train track "growth" and the natural
diamond is different. The other is to mimic the growing conditions
of natural diamonds and grow within a few months.
Characteristics Of Lab Grown Diamonds
| The Difference Between Lab Diamond And Natural Diamond |
| Attribute | Lab Grown Diamonds | Natural diamond | Distinction |
| Chemical composition | C(carbon) | C(carbon) | No |
| Refractive index | 2.42 | 2.42 | No |
| Relative density | 3.52 | 3.52 | No |
| Dispersion | 0.044 | 0.044 | No |
| 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 |
Resistivity | 1016 OHM-CM | 1016 OHM-CM | No |
Compressibility | 8.3*10-13 M2/N | 8.3*10-13 M2/N | No |
From a scientific point of view, man-made diamonds are the same as
natural diamonds. The only difference is where they are formed.
Prospects And Advantages Of Lab Grown Diamonds
In recent years, the diamond is more and more prosperous in the
global diamond market, especially the most mature market in the
United States, Europe and Asia region also gradually to follow
suit. At present, the artificial planting diamond accounted for
about 10% of the world's diamond market, but the market demand is
very big, especially in more than one carat of white diamonds.
Natural diamond mines will be exhausted, and the main mineral
resources still have more than ten years of service life. Natural
diamond supply on the market will gradually by planting a diamond.
So there is a big market for growing diamonds. In addition, the
application of CVD diamond in civil industry will gradually mature
and develop in recent years. The demand for jewelry and diamonds is
10 to 100 times higher.
