The GIA Diamond Dossier is a condensed diamond grading report issued by the Gemological Institute of America for polished diamonds weighing less than 1.00 carat. It records the same core grading determinations as GIA's full Diamond Grading Report — carat weight, colour grade, clarity grade, and, for standard round brilliants, a cut grade — along with measurements, polish, symmetry, and fluorescence assessment, but omits the plotted clarity diagram that maps the precise position and nature of inclusions. In its place, GIA laser-inscribes the unique report number directly onto the diamond's girdle, providing a permanent, verifiable link between the stone and its documentation.

What the Dossier Includes

Despite its abbreviated format, the Dossier upholds the same grading standards applied to larger stones. A typical Dossier records:

• Carat weight to the nearest hundredth of a carat
• Colour grade on GIA's D-to-Z scale
• Clarity grade on GIA's eleven-grade scale (FL through I3)
• Cut grade for standard round brilliant-cut diamonds (Excellent through Poor)
• Polish and symmetry grades
• Fluorescence (None, Faint, Medium, Strong, or Very Strong, with colour noted)
• Measurements (diameter range and depth for rounds; length, width, and depth for fancy shapes)
• The laser-inscribed report number, confirmed as present on the report itself

What the Dossier Omits

The principal difference between the Dossier and the full Diamond Grading Report is the absence of a clarity plot — the schematic diagram on which a grader maps the type, size, and location of each clarity characteristic. For diamonds in the lower clarity grades, where inclusions are readily visible and their positions less commercially significant, this omission is generally acceptable to the trade. For stones graded VVS2 or higher, however, many buyers and dealers prefer the full report, since the plot provides an additional layer of identity confirmation and documents characteristics that may be difficult to locate without guidance.

Laser Inscription and Verification

The girdle inscription is a defining feature of the Dossier format. Using a precisely controlled laser, GIA inscribes the report number — and optionally a personal message or retailer identifier requested by the submitting party — onto the girdle facets of the diamond. The inscription is invisible to the naked eye but legible under ten-power magnification. It allows any subsequent owner, dealer, or laboratory to cross-reference the stone against GIA's online Report Check database, confirming that the physical diamond corresponds to the grading information on record. This feature is particularly valuable in the secondary market and in jewellery manufacturing, where individual stones may be separated from their paperwork during setting or resale.

Position in the Trade

The Dossier format was introduced to serve the high-volume segment of the diamond market — commercial-quality melee and near-gem stones in the 0.18 to 0.99 carat range that are set in finished jewellery and sold at retail price points where the cost of a full grading report would be disproportionate. The reduced fee and faster turnaround make it the standard certification choice for manufacturers supplying chain jewellery, bridal collections, and fashion pieces. Diamonds reaching or exceeding 1.00 carat are conventionally submitted for a full Diamond Grading Report, which carries greater detail and, in the market's perception, greater authority for stones of that value.

It should be noted that the grading rigour is identical across both report types; the Dossier is not a lesser grade of examination, only a more concise presentation of its findings.
