Importance Of Certification

Around the world, IGI grading reports bring confidence to buyers and sellers alike.

The value of a precious stone is determined by its gemological makeup, natural rarity and finished quality. Gemstones of similar appearance can have notably different values. In the modern world, even experts require specialized tools to detect treatments, enhancements and synthetics.
