Gemological reports
Reports document diamond and gemstone features and known treatments.
Since 1977, EGL USA has operated a gemological laboratory in New York's diamond district. Its gemologists test and analyze diamonds, colored diamonds, colored gemstones, and jewelry, documenting stone features and known treatments in reports. The lab also provides supporting services, including photographic identification marks and cold laser inscription. Reports cover lab-grown diamonds, with specialized documentation and inscriptions, and the lab develops methods for identifying mounted lab-grown melee diamonds. EGL USA has been independently owned and operated since 1986, with a second laboratory in Los Angeles. Its North American labs conduct evaluations and gemological research, and provide resources and dialogue for customers and industry experts.
