How Are Lab Diamonds Made?

Lab-created Diamonds There are two processes labs use to grow diamonds - High Pressure-High Temperature (HPHT) and Chemical Vapor Deposition (CVD). Synthetic diamond is a diamond made of the same material as natural diamonds: pure carbon, crystallized in an isotropic 3D form. Lab created diamonds display the same physical, chemical, and optical characteristics as natural diamonds, along with the same fire, scintillation, and sparkle. Since no mining is necessary to produce these gemstones, they are an especially environment friendly choice.
