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?
