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.
