Lab Grown HPHT Diamonds Description
Diamond is considered the hardest material in the world. There are 10 levels of Mohs hardness, with diamond being the highest. Since it was known that diamonds are made of pure carbon, more and more people began to study diamonds in the laboratory under high temperature and pressure. At present, in high temperature and high pressure lab diamond raw materials industry development is rapid, widely used in various industries and processing industry.
Although the environment and conditions of lab-grown diamonds are different from those of natural diamonds, both natural and laboratory diamonds are pure carbon crystals and their physical properties, chemical properties, crystal structure and optical properties are identical. Diamonds grown and mined in a lab are real diamonds.
Artificial diamond, commonly known as laboratory diamond, is formed under high temperature and high pressure by imitating the crystallization process of natural diamond. Natural diamonds are formed in natural environments and are often mixed with other elements, which makes some natural diamonds not completely transparent and can display specific colors. For example, some have pink diamonds, some have a touch of blue, and some have light yellow. The diamond growth under high temperature and high pressure in the lab. Less impurities than natural diamonds, so more pure and transparent.
Under natural conditions, however, the high temperature and high pressure (HPHT) or chemical vapor deposition (CVD) technology can now be simulated in the lab production of natural diamonds, in the lab production of gem grade diamond can be produced in a short span of a few weeks.

Characteristics Of Lab Grown HPHT CVD Diamonds
Diamonds grown in a lab are grown in a lab. Advanced equipment is used to simulate the environment in which natural diamonds are formed. Lab-produced diamonds are usually produced in the lab for several weeks. Natural diamonds form naturally, as a result of billions of years of high temperatures and pressures. The chemical differences between the two are the same.
There is no significant difference between lab-grown diamonds and natural diamonds. Even professional gemologists also need special equipment to identify them. Through the amplification, professionals will be able to identify diamond inclusions grown in the laboratory and the nuances.
