Lab Created Diamonds Description
Lab-grown diamonds are also known as lab-made diamonds. Laboratory, there are two main breeding methods of diamond: CVD and HPHT.
Diamonds are considered the hardest material in the world. According to the grades of mohs hardness is divided into 10 levels, including diamond as the highest level. Since people know that diamond is composed of pure carbon that day, more and more people have studied in the laboratory to cultivate high temperature and high pressure diamond. At present, the high temperature and high pressure lab diamond raw materials industry development is rapid, widely used in various industries and processing industry.
High temperature and high pressure synthesis of diamond technology originated in the 1950 s, was originally used in aviation and military industry, nearly 10 years to realize a qualitative leap in the technological gem grade synthetic diamond both in terms of quality and cost are reached the market level.
Artificial diamonds, often referred to as lab-grown HPHT diamonds, are created by mimicking the crystallization process of natural diamonds. Natural diamonds are formed in the natural environment, often mixed with other elements together, making some natural diamonds are not completely transparent, can present a particular color. For example, some have pink diamonds, some have a touch of blue, and some have light yellow. High temperature and high pressure diamonds were grown in the lab, compared with natural diamond less impurities, so they are more pure, more transparent.
Natural diamonds take millions of years to form. Before the eruption, about 150 to 200 kilometers deep underground lava Wells can slowly cooling in the crater, has often been blocked because the crater of the volcano. Pure carbon material pressure is 4.5 * 10 ^ 6 ~ 9 Pa. When the temperature drops to 1000 ~ 1250℃, natural diamond crystals are formed. In some parts of the earth with the physical and chemical conditions of forming the diamond.
However, under the condition of natural production of natural diamond, can now be simulated in the laboratory, the use of high temperature and high pressure (HPHT) or chemical vapor deposition (CVD) techniques, in just a few weeks can produce laboratory production of gem grade diamond.

Characteristics Of Lab Created Diamonds
Lab-grown diamonds are grown in the laboratory. People use advanced equipment to simulate the environment in which natural diamonds are formed.
This formation process is the main factor that distinguishes lab-created diamonds from mined diamonds. Lab-grown diamonds can be mass-produced within a few weeks. As a result, laboratory-grown diamonds are much cheaper than natural diamonds of the same size and quantity.
The synthetic diamond is the product of the development of high technology. Synthetic diamonds is more environmentally friendly and saves labor costs.
| 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 |

| 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 exactly the same, the only difference is that the formation of their location.
