Two methods can produce jewelry-quality diamonds: HPHT and CVD.
HPHT is an abbreviation for High Pressure/High Temperature. This method replicates the natural formation of diamonds by subjecting carbon to high temperatures and pressing it together. This expensive process necessitates a significant amount of energy.
CVD is an abbreviation for Chemical Vapor Deposition. A seed crystal chamber is filled with a mixture of hydrogen and methane gas. Microwave power often heats the chamber to a high temperature, which excites the gas. The diamond grows on the seed crystal..
Certified gemological institutes grade lab-grown diamonds using the same 4 Cs that are used to grade naturally mined diamonds. It means that the properties of each diamond, such as its color grade, carat weight, clarity grade, and cut grade, are validated by a diamond certificate like the mineral one.
The most well-known grading laboratories that give this type of certificate are the Gemological Institute of America (GIA), the American Gem Society (AGS), and the International Gemological Institute (IGI). You can make an informed decision and compare similarly graded diamonds by having a certificate like these.
The main difference is how each one is made. The mineral diamond is formed by a natural process dependent on extremely long natural factors. On the other hand, the laboratory diamond is a more efficient approach to producing diamonds with the same appearance and physical, chemical, optical, and atomic properties.
Furthermore, there are many difficulties in extracting mineral diamonds, while those made in laboratories are much more ethical and eco-friendly.
