White Polish Diamond 1-8ct Certified Lab Grown Diamonds for Ring
Lab Grown Diamonds Description
Basically speaking, lab grown diamond and natural diamond have the
same physical properties, chemical composition and crystal
structure as the natural diamond. It can not be called fake
diamonds, but the "growth" trajectory and environment of cultivated
diamonds and natural diamonds are different. One is honed over
hundreds of millions of years, and the other is to simulate the
growth environment of natural diamonds, which takes a few months to
grow.
Lab grown diamond and the natural diamond are the same in nature,
even the hardness is the same, the biggest difference is in the way
of formation.
Characteristics Of Lab Grown Diamonds
There are two kinds of mass-produced diamond Deposition methods on
the market: Chemical Vapor Deposition, CVD, and High Pressure High
Temperature, High Temperature and High Pressure, HPHT.
① High temperature and pressure (HPHT) diamond cultivation
technology: the first generation of diamond growth technology, high
temperature and pressure technology completely simulates the growth
process of natural diamond, reproduce the reaction of carbon layer
on the ground and convert graphite into lab grown diamond;
(2) chemical vapor deposition (CVD) diamond cultivation techniques:
with sand or patches to the size of the diamonds as seeds, using
microwave to diamond can grow in the environment of high
temperature and low pressure, adding up to 5537 ℃ in plasma reactor
carbon atoms, atoms can one by one, attached on a thin piece of
diamond crystals, 'growing up gradually become great lab grown
diamond.
| 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
Through the reflection of the major diamond traders, we can see
that the diamond industry does not reject the cultivation of
diamonds, but laboratory-grown diamonds and natural diamonds are
still two completely different concepts. Most practitioners would
like to see the industry become more regulated, which would allow
consumers to better distinguish between cultured and natural
diamonds and draw a relatively clear line between lab-grown and
natural diamonds.
After all, lab-grown diamonds are real diamonds. Lab-produced
diamonds are lab-produced "gems" that are design elements for
everyday accessories in the mid-to-low market. Lab-grown diamonds
are meant to be worn.
