IGI Diamond Reports give an accurate assessment of a diamond’s cut, color, clarity and carat weight according to strict international standards.
IGI Diamond Reports are issued for diamonds of any size; a plotted diagram of the characteristics and a graphic representation of proportions appear on many of our documents.
IGI Diamond Reports have different formats and presentations, customized to serve a wide range of consumer demand in our different worldwide markets. Regardless of format, every IGI Diamond Report is issued according to the strict international standards and security features for which IGI is known.
Diamonds with permanent treatments are certified with such treatments noted prominently in the comment section of the report. IGI Diamond Reports are not issued for diamonds with non-permanent treatments.
Gemstones should only change hands when accompanied by a certificate attesting to quality. Regardless of location or marketplace, an authentic IGI Laboratory Report is the common language of trust and confidence in the gemological world.
The value of a precious stone is determined by its gemological makeup, natural rarity and finished quality. Diamonds and gemstones of similar appearance can have important differences in value. Even experts need powerful analytic tools to detect synthetics, treatments and enhancement processes.
With more locations around the globe than any other laboratory, IGI is the world’s most trusted name for the expert and impartial grading of diamonds, gemstones and jewelry.
