1.50 ct Round Brilliant Laboratory-Grown Diamond
94/100 · Signature
An unusually disciplined report profile.
What reads well
- Crown 36.1° with pavilion 40.4° sits in the well-regarded pairing zone for brightness and fire.
- Table 58% and depth 62.4% are within the classic round brilliant range.
- The IGI Excellent cut grade corroborates the measured proportions.
- Excellent polish and symmetry, the top finish grades.
- D color is in the colorless range.
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?
