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.
