Lab Created Diamonds Description
Lab created diamond is a small diamond as the seed, through the
laboratory to simulate the growth of natural diamonds to grow. It
has the same physical, chemical and optical properties as natural
diamond, and the hardness is 10. There are two ways to produce and
grow diamonds. One is high temperature and pressure, or HTHP. This
method is through the six-side top press (figure below). To put it
simply, it has six different sides and three directions, namely up
and down, left and right sides and front and rear sides. The carbon
source and metal catalyst are placed in each other's growth
chamber, and the carbon heating rod is used to heat up, forming an
environment of 55,000-60,000 atmospheric pressure and temperature
above 1400℃. The device can grow crystals of synthetic diamonds
that look exactly like natural diamonds.
Another way is the chemical vapor deposition (CVD), the method must
first have a seed of natural diamond chips, also need to use the
methane gas, methane under the action of energy, forming a carbon
plasma, the plasma like dust, slowly through the air to the seed of
diamond chips, bit by bit deposition. Carbon atoms from methane gas
are deposited on seed diamonds, which grow at a rate of 0.007
millimeters per hour. In a laboratory environment, one-carat
diamonds can be grown in a week. Their hardness and purity are
comparable to natural diamonds, but the price is only one-sixth of
that of natural diamonds. The purity and clarity of diamonds grown
by this method are particularly high, and currently occupy a large
share of the gem-grade lab-grown diamond market.

Characteristics Of Lab Created Diamonds
Lab-grown diamonds are also diamonds, and artificially produced
diamonds 4C are of higher quality than natural diamonds. Of course,
it is not absolute, but the diamond that is sold on the market at
present acts the role of article 4C that basically won't have
artificial cultivation diamond is high in quality, natural diamond
and lab grown diamond each have advantages and disadvantages.
The composition and hardness of lab grown diamonds and natural
diamonds are the same. Simply put, they are not afraid to scratch,
even if you scratch 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.
Lab grown diamond and natural diamond from the appearance of the
point of view is not very different, but from the quality of the
cultivation of diamond quality will be better, mainly because of
the cultivation of diamond can be a little quality control, the
general output of diamond quality is better. And natural diamond as
a result of do not have external force action, direct natural form,
come quality grade can be grasped more hard so, bring about diamond
of a high quality rare world to beg hard.
