3.23 ct Emerald Diamond

88/100 · Refined

A strong candidate on paper; confirm its light pattern in imagery.

What reads well

  • A 1.42:1 length-to-width ratio sits in the classic emerald cut range.
  • Face-up spread (10.31 × 7.24 mm) is typical or better for a 3.23 ct emerald cut.
  • Table 64% and depth 64.5% fall in the typical emerald cut range.
  • Excellent polish and symmetry, the top finish grades.
  • VS1 clarity is typically eye-clean in an emerald cut.

What deserves a closer look

  • H color in a 3.23 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.
  • Not stated on the report: culet. This is not assumed to be favorable, and confidence is lower.

The reading, field by field

Table · Ideal
At 64%, the table sits within the typical 60–69% range for an emerald cut, balancing brightness with fire.
Total depth · Ideal
64.5% 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 1.42:1 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 · Ideal
Excellent symmetry is the top finish grade — facets are cleanly executed with nothing that would soften sparkle.
Girdle · Ideal
Slightly thick (polished): a durable girdle thickness that doesn't hide meaningful weight.
Color · Favorable
H is near-colorless and faces up white in most settings, though an emerald cut can show a hint of warmth at the corners.
Clarity · Favorable
VS1 is typically eye-clean, though step cuts show inclusions more readily — worth a close look at the images.
Fluorescence · Favorable
Medium Blue fluorescence is rarely visible in normal lighting.

What to check on the exact stone

  • Does the feather reach the outer edge where a setting prong could put pressure on it?
  • Can I view this stone in daylight to see if the blue fluorescence helps it look whiter?
  • 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?
