IGI report LG781618103
1.00 ct Round Brilliant Laboratory-Grown Diamond
91/100 · Refined
A strong, composed candidate on paper.
What reads well
- Table 56% and depth 60.3% are within the classic round brilliant range.
- The IGI Ideal cut grade corroborates the measured proportions.
- Excellent polish and symmetry, the top finish grades.
- F color is in the colorless range.
- VVS2 clarity: inclusions are not a practical visual factor.
What deserves a closer look
- Crown 33.1° / pavilion 40.4° fall outside the pairing zone associated with strong light return.
What to check on the exact stone
- Does a gray ring or glassy patch show around the center when you look straight down?
- Does this HPHT-grown diamond look neutral white beside another stone in daylight, with no gray or blue cast?
- Can you show me the inscribed report number under a loupe before it is set?
