What reads well

- Face-up spread (5.48 × 5.41 mm) is typical or better for a 1.00 ct Asscher / square emerald.

- Excellent polish and symmetry, the top finish grades.
- F color is in the colorless range.
What deserves a closer look
- Screening only: for this Asscher / square emerald, check images or video of the exact stone for the concentric "hall of mirrors", the windmill pattern at the corners and any see-through window.
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?
