An unusually disciplined report profile.
What reads well

- Face-up spread (7.47 × 5.34 mm) is typical or better for a 1.37 ct emerald cut.
- Table 64% and depth 63.9% fall in the typical emerald cut range.
- Excellent polish and symmetry, the top finish grades.
- D color is in the colorless range.
What deserves a closer look
- Screening only: for this emerald cut, check images or video of the exact stone for the "hall of mirrors" step pattern, any see-through window under the table and clean corners.
What to check on the exact stone
- With open step facets, is the center completely eye-clean without any visible dark marks?
- 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?
