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 kinds of production and cultivation of 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. This equipment can be produced with natural diamond exactly the same 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 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. The hardness and the purity and natural diamond, but the price is only one 6 of the natural diamond. Diamonds grown this way are of exceptional purity and clarity and currently occupy a large share of the market for laboratory-grown gem-grade diamonds.

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

Diamonds are cheap and good to grow. Laboratory production of diamond and natural diamond no 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 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.
