Lab Grown Loose Diamonds Description
Laboratory diamonds are real diamonds. Carbon is the main component
of natural and man-made diamonds. Laboratory grown diamonds are
diamonds grown in the laboratory using equipment that simulates the
natural diamond growth environment. Synthetic diamonds have the
same chemical and physical properties as natural diamonds in terms
of hardness, thermal conductivity and strength. Diamonds grown in
the laboratory are diamonds grown in the laboratory. Their chemical
composition is the same as that of natural diamonds, and they are
also exactly the same optically. Artificial diamonds have the same
hardness and durability as natural diamonds. Diamonds grown in the
laboratory are the same as natural diamonds after polishing and
cutting. They have the same brightness and flame.
Can we distinguish between laboratory diamonds and natural
diamonds?
Yes, only diamond professionals can use professional diamond
identification equipment to identify the difference between
laboratory produced diamonds and natural diamonds.
High temperature and high pressure method and chemical vapor
deposition method are two main methods to manufacture laboratory
diamond.
High temperature and high pressure method (HTHP) uses graphite as
raw material and introduces appropriate metal catalysts, such as
Fe, Co, Ni, Mn, Cr, etc., which can synthesize diamond at tens of
thousands of atmospheres above 2000K.
CVD: chemical vapor deposition (CVD) is a method of decomposing raw
materials at high temperature to produce active particles such as
carbon atoms or methyl groups, and depositing and growing diamond
films on the substrate (substrate) under certain process
conditions.
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 diamond and natural
diamond is the same, the only difference is that where they are
formed.
Prospects And Advantages Of Lab Grown Diamonds
Natural diamonds are formed naturally and are the result of
billions of years of high temperature and high pressure. Laboratory
diamonds are produced in the laboratory, usually within a few
weeks. The chemical properties of the two are the same.
So how to distinguish between man-made diamonds and natural
diamonds?
There is no obvious difference between laboratory cultured diamonds
and natural diamonds. Even professional gemologists need special
equipment to identify them. By zooming in, professionals will be
able to distinguish the subtle contrast between diamond inclusions
grown and mined in the laboratory.
