Lab Created Diamonds Description
Synthetic diamond cultivation methods mainly include HPHT high
pressure and high temperature method and CVD chemical vapor
deposition method, and the cultivation time is about half a month
to one month. 1) HPHT high pressure and high temperature method:
Pure toner is compressed into a growth capsule and then placed in a
culture chamber. At extremely high temperature (up to 1300-1600°C)
and pressure, carbon atoms are joined together to form diamond
crystals. It takes about two weeks to grow large diamond rough
particles of more than 10 carats. 2) CVD chemical vapor deposition
method: a diamond sheet is placed in a hollow chamber, which is
filled with a mixture of hydrogen and methane and heated to
vaporization under a specific pressure. Carbon atoms are deposited
layer by layer on the sheet to form a uniform diamond coating. It
takes nearly a month to grow a cut 1-carat CVD diamond crystal.

From a scientific point of view, cultivated diamonds are exactly
the same as natural diamonds, the only difference being where they
are formed.
Prospect Of Lab Created Diamonds
1. More and more recognized by the market
Cultivated diamonds have appeared in the global jewelry consumer
market from 2012 to 2015, but the product quality is poor and the
price advantage is not obvious. International jewelry giant
cultivating diamond jewelry market, overlay the federal trade
commission (FTC) for factors such as diamond justify promote
cultivation, breeding diamonds in industry organization to
establish, specification development, synthesis and evaluation
technology promotion, production scale and market share increase
obvious progress, The cultivation of diamonds is recognized by the
public.
2, more consistent with the trend of environmental protection
Cultivating diamonds has only one-seventh the environmental impact
of mining them. In terms of surface environment, the impact of
diamond cultivation on surface environment is only 1/1,281 of that
of diamond mining. In terms of carbon emissions, cultivating
diamonds is only one and a half billion times less than natural
diamonds. In terms of water resources, growing diamonds uses only
6.9 billion times less water than natural diamonds. In terms of
energy, the energy consumption of cultivating diamond is only 1/2.1
of that of natural diamond. In general, the cultivation of diamonds
is in line with the promotion of the concept of sustainable
development in the current society, and more in line with the
pursuit of low-carbon and environmentally friendly lifestyle of the
young generation of consumers.
