5.0-7.0ct VS-SI Quality Lab Created HPHT Raw Material For Making 2
Carat 3 Carat Polish Diamonds
Lab Created HPHT Raw Material Description
Diamonds represent firmness and invincible strength. For a long
time, diamonds have been a symbol of power, status and wealth. In
the hearts of modern people, diamonds, as a symbol of love and
promise of marriage, represent eternal love and loyalty, and are an
important way for both parties to express their love.
Laboratory-made diamonds and natural diamonds have the same
chemical structure, but the method and time of their formation are
different. Laboratory-made diamonds can be mass-produced in the
shortest time, while natural diamonds are formed from a single
element (carbon) deep in the earth under high temperature and high
pressure environment, after billions of years, and then mined.
Although synthetic diamonds are grown in laboratories, they are
composed of carbon atoms, have the same physical properties and
chemical composition as natural diamonds, and have fewer
impurities, higher purity, and lower price than natural diamonds.
In fact, synthetic diamonds are not a new technology. As early as
1953, the Swedish Electric Power Company successfully synthesized
40 small diamonds using high temperature and high pressure
technology for the first time, but it has not been announced
publicly. In 1955, General Electric Company of the United States
successfully synthesized small diamonds by using the static
pressure coal melting method. In 1959, De Beers successfully
synthesized diamonds using epitaxial growth technology. Since then,
industrial-grade diamond synthesis technology has been widely used,
and commercial production has gradually begun.
Many people in the industry are optimistic about the market
prospects of lab diamonds, because the laboratory production
process is very environmentally friendly, without the environmental
impact of traditional diamond mining, and the price is cheaper.

Lab Created HPHT Raw Material Introduction
Natural diamonds are created by nature and are the result of high
temperature and pressure formed over billions of years. The Lab
Grown Diamonds are produced in the laboratory, usually in a few
weeks. The chemical difference between the two is same.
So how do you distinguish between Lab Grown Diamonds and natural
diamonds?
There is no obvious difference between the Lab Grown Diamonds and
natural diamonds. Even professional gemologists need special
equipment to identify them. By zooming in, professionals will be
able to discern subtle contrasts in diamond inclusions grown and
mined in the laboratory.
