The Importance of Grading
Even experts require advanced instruments to determine a gemstone’s true nature and all of its specifics. Around the world, IGI grading reports bring confidence to buyers and sellers alike.
Importance of Certification
Screening
IGI screens every gemstone using state of the art technologies to determine natural, laboratory grown or simulant origin. Graduate gemologists conduct further analysis and assessment to detect treatments or enhancements.
Authenticity
The value of a precious stone is determined by its overall gemological makeup, natural rarity and finished quality. Gemstones of similar appearance can have notably different values, making expert assessment and reporting vital to a gemstone’s value proposition.
Confidence
Gemstones and jewelry should only change hands when all parties are confident in the details. Regardless of location or marketplace, an IGI report is the common language of trust in the gemological world, and an essential part of any transaction.
