Lab Created Diamonds Description
Lab created diamond is a small diamond as a seed, through the laboratory to simulate the growth of natural diamond growth. It has the same physical, chemical and optical properties as natural diamond and has a hardness of 10. There are two ways to produce and grow diamonds. One is high temperature and pressure (HTHP). This method is through the six sides pressure (below). In short, it has six different sides, three directions, namely up, down, left and right, front and back. Carbon source and metal catalysts are placed in the growth chamber, using carbon heating rod heating, forming atmospheric pressure, temperature above 1400 ℃, 55000-60000. The device can grow synthetic diamond crystals that look exactly like natural diamonds.
Another method is the chemical vapor deposition (CVD), the method of natural diamond must first have a seed chips, also need to use methane gas, methane under the effect of energy, the formation of carbon plasma, plasma, like dust, slowly the seeds of diamond chips in the air, little by little. Carbon atoms in the methane gas are deposited on the seed diamond, which grows at a rate of 0.007 millimeters per hour. In a laboratory setting, one-carat diamonds can be grown in a week. It has the same hardness and purity as natural diamonds, but costs only one-sixth as much. In this way, the growth of diamond particularly high purity and clarity, currently in laboratory cultures of gem grade diamond occupies a large market share.

Characteristics Of Lab Created Diamonds
Lab-grown diamonds are also diamonds, and artificially produced 4C diamonds are of higher quality than natural diamonds. , of course, this is not absolute, but sales of diamonds on the market at present basically there will be no article 4 c of artificial cultivation diamond jewelry high quality, natural diamond and lab-grown diamond each have advantages and disadvantages.Laboratory composition and hardness of the diamond and natural diamond is the same. Simply put, they are not afraid to scratch, even if you cut them with sandpaper or a knife.
Growing diamonds is cheap and good. There is little difference between lab-grown diamond and natural diamond in appearance, but it can be found that lab created diamond of the same quality grade is much cheaper than natural diamond, and some even have one-fifth of the price of natural diamond.Laboratory development of diamond and natural diamond appearance is not very different point of view, but from the quality of the cultivation of the diamond quality will be better, mainly because of the cultivation of the diamonds may be a little quality control, general diamond quality better output. And natural diamond with no external force, naturally formed directly, since the level of quality will be more difficult to grasp, resulting in a high quality rare diamond is hard to find.
