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 |

| 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!
