IGI report LG678537780
1.19 ct Round Brilliant Laboratory-Grown Diamond
94/100 · Signature
An unusually disciplined report profile.
What reads well
- Crown 33.4° with pavilion 40.9° sits in the well-regarded pairing zone for brightness and fire.
- The IGI Ideal cut grade corroborates the measured proportions.
- Excellent polish and symmetry, the top finish grades.
- E color is in the colorless range.
- VS1 clarity is typically eye-clean in a round brilliant.
What to check on the exact stone
- With a shallow 59.2% depth, can you see a glassy, see-through patch in the center?
- Does the large table look bright but flat, with less colored fire than you expected?
- 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?
