What information is commonly included in independent diamond grading reports?

• A. Retail price and warranty terms
• B. Country of origin only
• C. Marketing claims and brand name
• D. Color grade, clarity grade, cut grade, and carat weight (where applicable)

Answer: (D)

Independent diamond grading reports are meant to document objective, measurable properties that affect a diamond’s value and appearance. The core information they routinely include are the four Cs: color grade, which rates how colorless the diamond is; clarity grade, which notes inclusions and blemishes; cut grade, which assesses how well the stone's proportions and finishes maximize brilliance; and carat weight, the precise mass of the diamond. These elements come from standardized scales used across labs, making it possible to compare stones reliably.

Prices, warranties, and branding fall outside the objective assessment of the diamond itself. Country of origin isn’t the focus of standard grading, and marketing claims or brand names aren’t part of the independent evaluation. Some reports may include additional technical details (like measurements, fluorescence, polish, or symmetry), but the four Cs are the core information used to convey the stone’s value.
