The Full Gemstone Examination Report (FGX): The FGX is the equivalent of the FDX report but is issued only for color gemstones. Depending on the gemstone’s characteristics, the FGX Report may include weight, shape, measurements, color, information about the presence or absence of treatments, and more.
GSI also offers a number of other reports for colored gemstones: IGX Report (passport size), SGX Report (3.75″ x 2.75″, letter head format), and the MGX Report (credit card size).
