88/100 · Refined
A strong candidate on paper; confirm its light pattern in imagery.
What reads well
- A 1.02:1 length-to-width ratio sits in the classic Asscher / square emerald range.
- Table 63% and depth 67.2% fall in the typical Asscher / square emerald range.
- Excellent polish and symmetry, the top finish grades.
- D color is in the colorless range.
- IF clarity: inclusions are not a practical visual factor.
What deserves a closer look
- Face-up area is about 10% below typical Asscher / square emeralds of this weight, suggesting hidden weight in depth.
- Screening only: windowing, contrast and the step-cut "hall of mirrors" pattern in an Asscher / square emerald can only be judged from images or video of this exact stone.
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?
