Lab Grown Diamonds Description
Lab grown diamond is to artificially simulate the formation
conditions of natural diamond, so that the carbon of non-diamond
structure is transformed into the carbon of diamond structure. To
put it simply, the raw material of graphite powder is transformed
into diamond structure through high temperature and high pressure
processing.
There are two main processes used to produce lab grown diamonds:
high pressure and high temperature (HPHT) and chemical vapor
precipitation (CVD). Since 1950, the high pressure and high
temperature method was used for the first time to successfully
synthesize diamonds, and now the main countries that use this
technology to manufacture gem-grade synthetic diamonds are China,
Russia, the United States and so on.
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, cultivated diamonds are exactly
the same as natural diamonds, the only difference being where they
are formed.
Prospects And Advantages Of Lab Grown Diamonds
Lab grown diamonds and natural diamonds, in the rough state are
basically exported to India for processing and cutting, now India's
diamond processing industry is quite famous in the world. The
finished diamonds cut in India are exported to other countries for
jewellery assembly and processing.
The difference is that there is a clear limit to how much can be
extracted from natural drilling now that the technology is
available. The yield of lab grown diamonds is, by comparison,
infinite, and the huge difference in yield between the two is
naturally reflected in price, provided that the difference can be
identified. Gem-grade artificially cultivated diamonds have also
been sold for many years in the market, and the most intuitive
influence on its price is the rating of appraisal certificate.
Appraisal companies in various countries have appraisal and
certificate issuing services for artificially cultivated diamonds.
In the world, artificially cultivated diamonds are known as
"Laboratory Grown Diamond". China's national standard, called
"synthetic diamond". That is to say, they are different in terms of
volume, price and relevant standards. The relationship between
natural diamond and cultivation of diamond is co-existence and
win-win cooperation.
It is estimated that lab grown diamond jewelry, in the next one to
three years, may be fully into the view of the majority of
consumers. Part of the well-known businesses have also made the
layout of lab grown diamond jewelry early, lab grown diamond and
natural diamond consumption, further refinement and differentiation
of target consumer groups, to better meet the people's growing
needs for a better life tomorrow is coming.
