An unusually disciplined report profile.
What reads well

- Face-up spread (7.88 × 6.22 mm) is typical or better for a 1.53 ct cushion.
- Table 60% and depth 65.8% fall in the typical cushion range.
- Excellent polish and symmetry, the top finish grades.
- E color is in the colorless range.
What deserves a closer look
- Screening only: for this cushion, check images or video of the exact stone for the facet pattern (bold, chunky flashes or finer "crushed ice") and any dark areas under the table.
What to check on the exact stone
- Does this cushion produce broad, chunky flashes or small needle-like crushed-ice sparkle?
- 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?
