GIA report 5436321245
3.00 ct Round Brilliant Diamond
72/100 · Character
Distinctive trade-offs that should be viewed deliberately.
What reads well
- The GIA Excellent cut grade corroborates the measured proportions.
- Excellent polish and symmetry, the top finish grades.
- H color in a round brilliant usually faces up near-colorless once set.
- No fluorescence: no haze risk to weigh.
- Slightly thick girdle balances durability and weight retention.
What deserves a closer look
- SI2 is often not eye-clean in a round brilliant; view an image or video of this exact stone.
- Crown 33.5° / pavilion 41.6° fall outside the pairing zone associated with strong light return.
- Clouds are referenced on the report; confirm the stone looks transparent rather than hazy.
- Table 61% sits outside the preferred round range.
- Feathers are listed: check the plot for any that reach the girdle or surface, which matters for durability.
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
- 61.4% 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
- 33.5° sits in the 32–36° zone where crown angles typically balance fire and brightness.
- Pavilion angle · Closer look
- 41.6° is steeper than the narrow 40.5–41.3° zone. Deep pavilions can leak light through the sides and darken the center.
- 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
- 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
- H is near-colorless and faces up white in most settings.
- Clarity · Closer look
- SI2: inclusions may be visible to the eye. Confirm with images or video before buying.
- 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 center turn dark or lose sparkle when you tilt the diamond face-up?
- Does the large table look bright but flat, with less colored fire than you expected?
- Does the diamond look crisp and transparent in natural light, or is there any milky haze?
- Can you show me the inscribed report number under a loupe before it is set?
