Lab Grown Loose Diamonds Description
Laboratory diamonds are diamonds cultivated by machines in the
laboratory. After polishing and cutting, diamonds cultivated in the
laboratory are no different from natural diamonds. Diamonds
produced in the laboratory and natural diamonds are real diamonds.
The main chemical composition of diamonds produced in the
laboratory and natural diamonds is carbon.
At present, high temperature and high pressure method and chemical
vapor deposition method are the two main methods to prepare
laboratory diamonds.
Laboratory diamond forming machine can produce laboratory diamond
through high temperature, high pressure and CVD technology.
However, due to the different machines and technologies used in
diamond production by high temperature and high pressure and
chemical vapor deposition, people can distinguish diamonds produced
by high temperature and high pressure and chemical vapor deposition
from diamonds produced in the laboratory.
Fundamentally, synthetic diamonds and natural diamonds have
basically the same physical properties, chemical composition and
crystal structure as natural diamonds. But it cannot be called a
fake diamond, diamond "growth" in the cultivation of trajectory and
the natural diamond is different. The other is a simulation of
natural diamond growth environment, grow in 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, synthetic diamonds are identical
to natural diamonds, the only difference being where they are
formed.
Prospects And Advantages Of Lab Grown Diamonds
In recent years, diamonds have become more and more prosperous in
the global diamond market, especially in the United States, the
most mature market, and the Eurasian region has gradually followed
suit. At present, artificially planted diamonds account for about
10% of the world diamond market, but the market demand is large,
especially white diamonds with more than one carat. The natural
diamond mines will be exhausted, and the main mineral resources
will still have a service life of more than ten years. The supply
of natural diamonds in the market will gradually be obtained by
planting diamonds. Therefore, there is a large market space for
planting diamonds. Coupled with the application of CVD diamonds in
the civil industry, it will gradually mature and develop in recent
years. The demand for jewelry diamonds is 10 ~ 100 times.
