IGI report 763630013
1.33 ct Round Brilliant Diamond
82/100 · Considered
A balanced profile with a few questions to carry forward.
What reads well
- The IGI Excellent cut grade corroborates the measured proportions.
- Excellent polish and symmetry, the top finish grades.
- I color in a round brilliant usually faces up near-colorless once set.
- No fluorescence: no haze risk to weigh.
- Medium to 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 36.2° / pavilion 41.2° fall outside the pairing zone associated with strong light return.
What to check on the exact stone
- Does the steep crown give lively fire without making the center look darker?
- Is this SI2 diamond eye-clean face-up from about 10 inches away?
- Can you show me the inscribed report number under a loupe before it is set?
