What reads well
- A 1.01:1 length-to-width ratio sits in the classic Asscher / square emerald range.
- Face-up spread (8.77 × 8.65 mm) is typical or better for a 4.00 ct Asscher / square emerald.
- Table 65% and depth 68.5% fall in the typical Asscher / square emerald range.
- D color is in the colorless range.
- VVS2 clarity: inclusions are not a practical visual factor.
What deserves a closer look
- Very Good polish / Good symmetry is below the Excellent/Very Good standard and can soften sparkle.
- 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.
The reading, field by field
- Table · Ideal
- At 65%, the table sits within the typical 58–68% range for an Asscher / square emerald, balancing brightness with fire.
- Total depth · Ideal
- 68.5% is within the typical 60–70% range for an Asscher / square emerald, keeping weight where it contributes to face-up size and light return.
- Length-to-width · Ideal
- A 1.01:1 outline is within the classic 1–1.05:1 range for an Asscher / square emerald.
- Polish · Favorable
- Very Good polish is a fine result; the difference from Excellent is rarely visible without magnification.
- Symmetry · Closer look
- Good symmetry is below the grades most buyers target and can slightly soften crispness. Worth seeing the stone in person or on video.
- Girdle · Ideal
- Slightly thick, polished: a durable girdle thickness that doesn't hide meaningful weight.
- Culet · Ideal
- None: no visible culet facet when viewed face-up.
- Color · Ideal
- D is in the colorless range and faces up white in any metal.
- Clarity · Ideal
- VVS2: inclusions, if any, are only visible under magnification.
- Fluorescence · Ideal
- None: no meaningful effect on appearance.
What to check on the exact stone
- With open step facets, is the center completely eye-clean without any visible dark marks?

- Can you show me the inscribed report number under a loupe before it is set?
