GIA vs IGI vs HRD: Fancy Color Diamond Reports Compared

A laboratory report records the findings of a specific examination; it is not a valuation or a guarantee of future price. For a fancy color diamond, compare the exact report type, whether it addresses natural or laboratory-grown origin, whether color origin and treatments are stated, and whether the report number can be verified with the issuer.

GIA (Gemological Institute of America)

GIA's natural colored diamond services include reports with different scopes. Its Colored Diamond Grading Report includes color grade and origin, carat weight, clarity, and a plotted diagram; its color-only identification report has a narrower scope. Check the report name rather than assuming every GIA document contains the same fields.

IGI (International Gemological Institute)

IGI states that its Fancy Colored Diamond Report identifies natural or laboratory-grown origin and describes shape, measurements, fancy color, and other relevant gemological details. The comments section may contain treatment information. Verify the actual document and report number for the stone being offered.

HRD Antwerp

HRD Antwerp describes its Natural Diamond Colour Grading Report as stating color origin and color characteristics, including short- and long-wave luminescence. As with any issuer, confirm the report type, scope, number, and current verification record.

How S.RONEN Discloses Report Status

Most diamonds in our B2B inventory carry GIA grading reports. Some stones may carry a report from another recognized laboratory, such as IGI, or be offered without a grading report. The laboratory and report status are stated on each listing so buyers can evaluate every stone on its documented merits.
