Lab Grown HPHT CVD Diamonds Description

Laboratory diamonds are generally produced by chemical vapor deposition (CVD) or high pressure and high temperature (HPHT) processes and are of similar quality to natural diamonds. Rhinestones are often used to craft priceless jewelry, as they can be cut into a variety of shapes and polished to achieve many different finishes.

Although laboratory grown diamonds and natural diamonds grow in different environments and conditions, natural diamonds and laboratory grown diamonds are pure carbon crystals with the same physical, chemical, crystal structure and optical properties. The diamonds produced in the laboratory and mined are real diamonds.

Artificial diamonds, commonly known as laboratory diamonds under high temperature and high pressure, are formed by imitating the crystallization process of natural diamonds. Natural diamonds are formed in the natural environment and usually mixed with other elements, which makes some natural diamonds not completely transparent and can show specific colors. Diamonds grow under high temperature and pressure in the laboratory. Diamonds contain less 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 150 to 200 kilometers deep can slowly cool in the crater, usually 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, gem grade diamonds produced in the laboratory can now be produced under natural conditions, using high temperature and high pressure (HPHT) or chemical vapor deposition (CVD) technology to simulate the production of natural diamonds in the laboratory in a few 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.

In the past decade, synthetic diamond has received wide attention because it allows many new applications of diamond. Lab-grown diamond is an environmentally friendly product with pollution-free technology and no environmental pollution.

From a scientific point of view, synthetic diamond and natural diamond are exactly the same. The only difference is that they are formed in different positions.
