Lab Grown HPHT CVD  Diamonds Description

Diamonds are considered the hardest material in the world. There are 10 mohs scales of hardness, with diamond being the highest. Since it has been known that diamonds are made of pure carbon, more and more people have begun to study diamonds under high temperature and pressure in the laboratory. At present, high temperature and high pressure laboratory diamond raw material industry develops rapidly, widely used in various industries and processing industries.

Although lab-grown diamonds are in different environments and conditions from natural diamonds, both natural and laboratory diamonds are pure carbon crystals, and their physical properties, chemical properties, crystal structure and optical properties are the same. Lab-grown diamonds and mined diamonds are real diamonds.

Artificial diamonds, often referred to as laboratory diamonds at high temperatures and pressures, are formed by mimicking the crystallization process of natural diamonds. Natural diamonds are formed in the natural environment and are often mixed with other elements, which makes some natural diamonds not completely transparent and can take on a specific color. For example, some have pink diamonds, some have a touch of blue, and some have light yellow. Diamonds are grown in the laboratory under high temperature and pressure. There are fewer impurities than natural diamonds, so they are more pure and transparent.

Natural diamonds take millions of years to form. Before a volcano erupts, underground lava Wells about 150 to 200 kilometers deep can slowly cool inside the crater, often because the crater is blocked. The pressure of pure carbon material is 4.5 * 10 ^ 6 ~ 9pa. When the temperature drops to 1000 ~ 1250℃, natural diamond crystals are formed. Diamonds are formed under physical and chemical conditions in some parts of the earth.

However, lab-produced gem-grade diamonds can now be produced under natural conditions using high temperature and pressure (HPHT) or chemical vapor deposition (CVD) techniques to simulate the production of natural diamonds in a laboratory in a matter of weeks.

Characteristics Of Lab Grown HPHT CVD Diamonds

Laboratory cultivation of diamond is bred in the laboratory. People use advanced equipment to simulate the natural diamond formation of the environment. Laboratory-grown diamonds are usually produced in a lab for several weeks. Natural diamonds are created by nature, the result of billions of years of high temperature and pressure. Both on the chemistry of the difference is the same.

So how do you distinguish between laboratory cultivation of diamond and natural diamond?

Laboratory cultivation of diamond and natural diamond there was no significant difference. Even professional gemologists also need special equipment to identify them. By magnifying, professionals will be able to recognize in the lab, growth and production of diamond inclusions nuances.

From a scientific point of view, synthetic diamond and natural diamond exactly the same, the only difference is that the formation of their position.
