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.
