1 . D AT E
Date diamond was examined by GIA.
2. REPORT NUMBER
Unique GIA report number registered in GIA’s extensive global database.
3. SHAPE AND CUTTING STYLE
The outline of the diamond (shape) and the pattern of the facet arrangement(cutting style).
4. MEASUREMENTS
Diamond dimensions listed as “minimum diameter – maximum diameter xdepth” for round diamonds and “length x width x depth” for fancy-shapeddiamonds.

5 . C A R AT W E I G H T
Weight given in carats, recorded to the nearest hundredth of a carat. One carat
is equal to 1/5 of a gram.
6 . C O LO R G R A D E
The absence of color ranging from colorless to light yellow or brown whencompared to GIA Master Color Comparison Diamonds. Graded on a D-to-Z scale.
If “*” appears next to the color grade, a color treatment was detected.
7. CLARITY GRADE
The relative absence of inclusions and blemishes. Graded on a scale from
Flawless to Included based on size, nature, number, position, and relief ofcharacteristics visible under 10x magnification.

8. CUT GRADE
For standard, D-to-Z color, round brilliant diamonds. Cut grade incorporates theaspects of face-up appearance, design, and craftsmanship. Graded on a scalefrom Excellent to Poor.
9. POLISH
Smoothness of the diamond’s surface, assessed on a scale ranging fromExcellent to Poor.

1 6 . G I A C O LO R S C A L E
Illustrates the GIA Color grades and their relative positions in the GIA DiamondColor Grading System.
17. GIA CLARITY SCALE
Illustrates the GIA Clarity grades and their relative positions in the GIA
Diamond Clarity Grading System.

10. SYMMETRY
Exactness of the diamond’s outline, and the shape, placement, and alignmentof its facets, assessed on a scale ranging from Excellent to Poor.

18. GIA CUT SCALE
Illustrates the GIA Cut grades and their relative position in the GIA Diamond
Cut Grading System. Available for standard round brilliant cut diamonds in theD-to-Z color range and Flawless-to-I3 clarity range.

11. FLUORESCENCE
Strength and color of the diamond when viewed under long-wave ultraviolet
light. A fluorescence description of “none” represents a range of fluorescencefrom Indiscernible to Very Faint. Used for identification purposes.

1 9 . S E C U R I T Y F E AT U R E S
Microprinting, security screens, watermarks, a two-dimensional barcode,a hologram, and sheet numbering safeguard report integrity and facilitate
document authentication.

12. CLARITY CHARACTERISTICS
List of the most significant clarity characteristics present in the diamond thatjustifies the clarity grade; a maximum of four characteristics are listed.

20. QR CODE
A two-dimensional barcode that, when scanned, verifies data on the reportagainst the GIA database.

13. INSCRIPTION(S)Any text, symbols, logos, or a unique GIA report number inscribed on thediamond’s girdle.
14. COMMENTS
Additional identifying characteristics or features that are not otherwise
represented on the report. If a treatment is detected, such as laser drilling, it
would be described here.
15. PROPORTION DIAGRAM
Graphic profile representation of the diamond’s actual proportions.
