Lab Grown Diamonds Description
Laboratory breeding diamond, is a mature production technology is
divided into two categories, CVD method and the high temperature
and high pressure HPHT method, laboratory breeding diamond, as the
name implies, is the simulation of natural diamond growing
environment and crystallization properties, under laboratory
conditions using seed grows unceasingly, grow up and become, the
chemical, physical, atom, The light and all properties are
identical to those of natural diamonds.
Characteristics Of Lab Grown Diamonds
Crystal habit:
(1) Lab-grown diamonds are usually cubes, octahedrons and the
clustering of the two;
(2) Crystal plane texture: laboratory cultured diamond can show
dendritic, sand leakage or intersecting texture, the inoculation
surface rough;
(3) Seed crystal: seed crystal and seed crystal phantom zone exist;
(4) laboratory cultivated diamond type: laboratory cultivated
diamond is divided into type IIB or TYPE IIA, type IIB after high
temperature treatment can become Ib and Ia mixed type;
(5) inclusions: metal inclusions in needle-like, lamellar and
needle-point shape. A large number of metal inclusions make
synthetic diamond obviously magnetic and even conductive.
| 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
Experts predicted that this century will be the most significant
inventions of the big diamond, this prophecy has now become a
reality, and cultivate the diamond's main advantage is green (not
conflict blood diamonds, no mining environment pollution)
affordable (natural diamond prices more than 30%), excellent
quality (d-h color, VVS - SI clarity), can be customized
production, Various colors (white diamonds, pink diamonds, yellow
diamonds, blue diamonds) and fire color is extremely gorgeous! I
believe that in the near future, the cultivation of diamonds will
gradually be accepted by consumers, into thousands of households,
thus deeply rooted in the hearts of the people!
