5.04 ct Emerald Laboratory-Grown Diamond

90/100 · Refined

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

What reads well

  • A 1.50:1 length-to-width ratio sits in the classic emerald cut range.
  • Face-up spread (11.88 × 7.91 mm) is typical or better for a 5.04 ct emerald cut.
  • Table 64% and depth 66.6% fall in the typical emerald cut range.
  • Excellent polish and symmetry, the top finish grades.
  • F color is in the colorless range.

What deserves a closer look

  • 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.
  • Treatment status is not stated on the report. For a laboratory-grown diamond, ask whether it is as-grown or post-growth treated.

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
66.6% 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 1.5:1 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
Medium To Slightly Thick: a durable girdle thickness that doesn't hide meaningful weight.
Culet · Ideal
Long: a keel-line culet, normal for elongated step and modified cuts.
Color · Ideal
F 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?
  • Does this CVD diamond show any brown or gray undertone face-up in daylight?
  • Can you show me the inscribed report number under a loupe before it is set?
