GJLI Diamond Reports give an accurate assessment of a diamond's cut, color, clarity and carat weight according to strict international standards.
GJLI 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.
GJLI 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 GJLI Diamond Report is issued according to the strict international
standards and security features for which GJLI is known.
Diamonds with permanent treatments are certified with such treatments noted prominently in the comment section of the
report. GJLI 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 GJLI Laboratory Report is the common language of trust and confidence in the gemological world.
