Lab Grown Diamonds Description
A kind of real diamond, obtained through technology.
Lab grown diamond growth principle: similar to the nature of fruit
growth. In the process of growth, carbon atoms are constantly
transformed into their own "tissue", and over time grow into a
gem-grade diamond, that is, to complete the mission of growth.
Lab grown diamond and mining diamond difference: access to
different sources, the naked eye can not distinguish, professional
identification instruments can see the diamond growth pattern is
different; Its chemical elements and light effect, hardness and
other physical effects of mining diamond consistent, authoritative
identification agencies can issue a certificate.
Common Lab grown diamond methods: HPHT (high temperature and high
pressure) and CVD (chemical vapor deposition)
The basic principle of CVD chemical vapor deposition method: The
free carbon is separated from the gas containing carbon element in
a relatively low temperature and low pressure environment, and the
carbon atom will continuously deposit and fall on the diamond seed,
gradually deposition and growth, and grow into a diamond.
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, lab grown diamonds are exactly the
same as natural diamonds, the only difference being where they are
formed.
Prospects And Advantages Of Lab Grown Diamonds
On the supply side, both artificially Lab grown rough diamonds and
naked diamonds are in short supply globally. Most of China's
artificially lab grown rough diamonds are exported to India, while
most of the naked diamonds are exported to Europe, the United
States, the Middle East and Southeast Asia. In terms of the
terminal market, the European and American consumer markets are
relatively mature, while the domestic market is in the growth stage
and has a large market space.
Demand for lab grown diamonds is in short supply, and the market
will improve as consumers embrace synthetic diamonds.
