Lab Created Diamonds Description

The lab-created diamond is a small diamond as a seed, through the laboratory to simulate the growth of natural diamonds. It is the same as the natural diamond physical, chemical and optical properties, hardness of 10. There are two kinds of diamond production and cultivation. One is high temperature and high pressure (HTHP). This method is done by six side pressing (down). In short, it has six different sides, three directions, namely up, down, left, right, front and back. Place the carbon source and the metal catalyst in the growth chamber, using carbon heating rod heating, forming atmospheric pressure, temperature above 1400 ℃, 55000-60000. This equipment can produce the completely same with natural diamond synthetic diamond crystal.

Another method is the chemical vapor deposition (CVD), the method of natural diamond must first have a seed chips, also need to use methane, the methane under the action of energy, the formation of carbon plasma, plasma, like dust, the seeds of diamond chips in the air slowly, bit by bit. Carbon atoms in the methane gas are deposited on diamond seeds, which grow at a rate of 0.007 millimeters per hour. In the laboratory environment, a carat diamond can be grown in a week. Diamonds have the same hardness and purity as natural diamonds, but are only one-sixth of the price. Production of diamonds in this way has a very high purity and clarity, currently in the lab production of gem grade diamond occupies a large share in the market.

Characteristics Of Lab Created Diamonds

Lab-produced diamonds are also diamonds, and artificially produced 4C diamonds are of higher quality than natural diamonds. , of course, this is not absolute, but on the market at present basic won't have article 4 c diamond sales of high quality artificial cultivation of diamond jewelry, natural diamond and laboratory breeding diamond each have advantages and disadvantages.

Laboratory composition and hardness of the diamond and natural diamond is the same. In short, they are not afraid of damage, even if you use sandpaper or cut them.

Diamonds are cheap and easy to grow. Laboratory production of diamond and natural diamond there is a difference in appearance, but can be found that the same quality grade of laboratory production of diamond is much cheaper than natural diamond, some even only one 5 of natural diamond.

Laboratory developed the appearance of the diamond and natural diamond is not much different point of view, but from the perspective of the cultivation of the quality of the diamond quality would be better, mainly because the train there may be a little diamond quality control, the general quality of diamond production is better. And natural diamond with no external force, natural form directly, because the quality will be more difficult to grasp, causing it difficult to find high quality rare diamonds.
