- Clouds are referenced on the report; confirm the stone looks transparent rather than hazy.
- Feathers are listed: check the plot for any that reach the girdle or surface, which matters for durability.
- H color in a 3.00 ct Asscher / square emerald may show some warmth, especially at the corners.
- 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
- 68.3% 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 · Ideal
- Excellent polish is the top finish grade — facets are cleanly executed with nothing that would soften sparkle.
- Symmetry · Favorable
- Very Good symmetry is a fine result; the difference from Excellent is rarely visible without magnification.
- Girdle · Ideal
- Thick, polished: a durable girdle thickness that doesn't hide meaningful weight.
- Culet · Ideal
- None: no visible culet facet when viewed face-up.
- Color · Favorable
- H is near-colorless and faces up white in most settings, though an Asscher / square emerald can show a hint of warmth at the corners.
- Clarity · Closer look
- SI2: inclusions may be visible to the eye. Confirm with images or video before buying.
- Fluorescence · Ideal
- None: no meaningful effect on appearance.
What to check on the exact stone
- Does the diamond look crisp and transparent in natural light, or is there any milky haze?
- Does the feather reach the outer edge where a setting prong could put pressure on it?
- 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?
