An unusually disciplined report profile.
What reads well
- Crown 34.2° 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.
- D color is in the colorless range.
What to check on the exact stone
- Can I see this stone in soft daylight away from store spotlights to verify its sparkle?
- Does the sparkle look bright and even all the way out to the edges?
- 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?
