0.6-4.0 Carat DEF Color VVS VS SI Purity Round Lab Grown Cut Loose Diamonds
Synthetic Diamonds Description
Diamonds are considered the hardest material in the world. Mohs hardness is divided into 10 grades, among which diamond is the highest grade. Ever since it was known that diamonds were made of pure carbon, more and more people have been working on high-temperature and high-pressure diamonds 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.
High temperature and high pressure synthetic diamond technology originated in the 1950s and was initially applied in aviation and military industry. The implementation of technology in the past 10 years has made gem-grade synthetic diamond achieve a qualitative leap in terms of quality and cost at the market level.
Artificial diamonds, often referred to as lab-grown HPHT diamonds, are created by mimicking the crystallization process of natural diamonds. Natural diamonds are formed in the natural environment and are often mixed with other elements, making some natural diamonds not completely transparent and able to 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 lab at 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 in the crater, often because the crater is blocked. The pressure of pure carbon material is 4.5 * 10 ^ 6 ~ 9 Pa. 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.
Under natural conditions, however, the production of natural diamonds in the lab can now be used in high temperature and high pressure (HPHT) or chemical vapor deposition (CVD) technique to simulate production laboratory production of gem grade diamond, just a few weeks.

Characteristics Of Lab Created Diamonds
Lab-grown diamonds are grown in the laboratory. People use advanced equipment to simulate the environment in which natural diamonds are formed.
This formation process is the main factor that distinguishes lab-created diamonds from mined diamonds. Lab-grown diamonds can be mass-produced within a few weeks. As a result, laboratory-grown diamonds are much cheaper than natural diamonds of the same size and quantity.
The synthetic diamond is the product of the development of high technology. Synthetic diamonds is more environmentally friendly and saves labor costs.
