Lab Grown Loose Diamonds Description
Laboratory breeding diamond, also known as synthetic diamonds, the artificial cultivation and laboratory created diamonds are in a highly controlled laboratory environment, use of advanced technology.
Although laboratory under the condition of the diamond is in a different environment and formed by natural diamond, but the natural diamond and laboratory are crystals of pure carbon, their physical properties, chemical properties, crystal structure and optical properties are the same. Lab production and mining of diamonds are real diamond.
Synthetic diamonds are formed by mimicking the crystallization process of natural diamonds. Natural diamonds are formed in the natural environment, often mixed with other elements, which makes some natural diamonds are not completely transparent, can present a particular color. For example, some diamond is pink, some are blue, some are yellow. Diamonds are grown in a laboratory under high temperature and pressure. There are fewer impurities than natural diamonds, so they are more pure and transparent.
Natural diamonds take millions of years to form. Before the eruption, about 150 to 200 kilometers deep underground lava can slowly cooling inside the crater, usually because the crater is blocked. The pressure of pure carbon material is 4.5*10^6~9pa. When the temperature dropped to 1000 ~ 1250 ℃, the formation of natural diamond crystals. Diamonds are formed under physical and chemical conditions in certain parts of the earth.
Laboratory, however, the production of gem grade diamond can now be produced in natural conditions, the use of high temperature and high pressure (HPHT) or chemical vapor deposition (CVD) techniques, in a few weeks simulation laboratory in the production of natural diamonds.

Characteristics Of Lab Grown Loose Diamonds
Laboratory grown diamonds are grown in the laboratory. People use advanced equipment to simulate the environment of natural diamond formation. Diamonds produced in the laboratory are usually produced in the laboratory for several weeks. Natural diamonds are created by nature and the result of billions of years of high temperature and high pressure. The chemical differences between the two are the same.
How to distinguish between diamond cultivation laboratory and natural diamond laboratory?
There is no significant difference between laboratory cultured diamond and natural diamond. Even professional gemologists need special equipment to identify them. Through amplification, professionals will be able to identify subtle differences in the growth and production of diamond inclusions in the laboratory.
| The Difference Between Lab Diamond And Natural Diamond | |||
| Attribute | Lab-Created 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, man-made diamonds are exactly the same as natural diamonds. The only difference is their formation position.
