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.

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 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.
