GIA report 2517178981
3.00 ct Round Brilliant Diamond
94/100 · Signature
An unusually disciplined report profile.
What reads well
- Crown 34° with pavilion 41° sits in the well-regarded pairing zone for brightness and fire.
- The GIA Excellent cut grade corroborates the measured proportions.
- Excellent polish and symmetry, the top finish grades.
- G color should face up white in most settings.
- VVS1 clarity: inclusions are not a practical visual factor.
What deserves a closer look
- Table 61% sits outside the preferred round range.
The reading, field by field
- Table · Closer look
- A 61% table is larger than typical for a round brilliant (53–59%). Large tables can read bright but flatter, with less fire and contrast.
- Total depth · Ideal
- 60.8% is within the typical 59.5–63% range for a round brilliant, keeping weight where it contributes to face-up size and light return.
- Crown angle · Ideal
- 34° sits in the 32–36° zone where crown angles typically balance fire and brightness.
- Pavilion angle · Ideal
- 41° is inside the narrow 40.5–41.3° zone where the pavilion returns light most efficiently.
- Polish · Ideal
- Excellent polish is the top finish grade — facets are cleanly executed with nothing that would soften sparkle.
- Symmetry · Ideal
- Excellent symmetry is the top finish grade — facets are cleanly executed with nothing that would soften sparkle.
- Girdle · Ideal
- Medium to slightly thick, faceted, 4.5%: a durable girdle thickness that doesn't hide meaningful weight.
- Culet · Ideal
- None: no visible culet facet when viewed face-up.
- Color · Favorable
- G is near-colorless and faces up white in most settings.
- Clarity · Ideal
- VVS1: inclusions, if any, are only visible under magnification.
- Fluorescence · Ideal
- None: no meaningful effect on appearance.
- Cut grade · Ideal
- Excellent as issued by GIA, on GIA's own scale. The measured proportions above tell you more than the label.
What to check on the exact stone
- Does the large table look bright but flat, with less colored fire than you expected?
- Does the feather reach the outer edge where a setting prong could put pressure on it?
- Can I see this stone in soft daylight away from store spotlights to verify its sparkle?
- Can you show me the inscribed report number under a loupe before it is set?
