4.00 ct Emerald Diamond
82/100 · Considered
A balanced profile with a few questions to carry forward.
What reads well
- A 1.39:1 length-to-width ratio sits in the classic emerald cut range.
- Face-up spread (10.39 × 7.47 mm) is typical or better for a 4.00 ct emerald cut.
- No fluorescence: no haze risk to weigh.
What deserves a closer look
- K color in a 4.00 ct emerald cut may show some warmth, especially at the corners.
- 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.
The reading, field by field
- Table · Closer look
- A 70% table is larger than typical for an emerald cut (60–69%). Large tables can read bright but flatter, with less fire and contrast.
- Total depth · Ideal
- 68.7% is within the typical 60–69% range for an emerald cut, keeping weight where it contributes to face-up size and light return.
- Length-to-width · Ideal
- A 1.39:1 outline is within the classic 1.3–1.5:1 range for an emerald cut.
- 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
- Slightly thick to thick, polished: a durable girdle thickness that doesn't hide meaningful weight.
- Culet · Ideal
- None: no visible culet facet when viewed face-up.
- Color · Closer look
- K shows visible warmth. It suits buyers who like a softer, warmer look, and pairs best with yellow or rose gold.
- 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
- Can you see straight through the center (windowing), or does it reflect clean steps?
- 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?
