Two main certified methods to produce synthetic diamonds.

  1. High Pressure High Temperature (HPHT)
  2. Chemical Vapour Deposition (CVD)

The lab-grown diamonds and synthetic diamonds can be distinguished on important parameters like color zoning, dark metallic inclusions, weak strains, UV light presence, distinctive patterns, dark spots inclusions, and other several display features. 

The Geological Institute of India Laboratory-Grown Diamond Grading Report offers the same information as the Geological Institute of India Diamond Grading Report for natural diamonds, using a more general description of colour, clarity and identification.

World-class apart, our Geological Institute of India Laboratory – Grown Diamond Grading Report includes added disclosure and identification. The laboratory-grown diamond’s girdle is laser inscribed with its report number and a statement that the stone is laboratory-grown. 

The grading process for Lab grown Diamond gemstones requires just as much skill, precision and knowledge as the grading of natural diamonds.

Lab grown diamonds are like real diamonds except they are not born in the crust of the earth but through chemical or physical processes in a recognized laboratory using latest technology. There are two main certified methods to produce synthetic diamonds.

  1. High Pressure High Temperature (HPHT)
  2. Chemical Vapour Deposition (CVD)
