IGI report LG782689644

5.04 ct Emerald Laboratory-Grown Diamond

89/100 · Refined

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

What reads well

  • A 1.43:1 length-to-width ratio sits in the classic emerald cut range.
  • Face-up spread (11.56 × 8.06 mm) is typical or better for a 5.04 ct emerald cut.
  • Table 62% and depth 66.1% fall in the typical emerald cut range.
  • Excellent polish and symmetry, the top finish grades.
  • No fluorescence: no haze risk to weigh.

What deserves a closer look

  • G color in a 5.04 ct emerald cut may show some warmth, especially at the corners.
  • VS2 in an emerald cut is usually eye-clean, but step cuts show inclusions more readily than brilliants; check the plot.
  • 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 62%, the table sits within the typical 60–69% range for an emerald cut, balancing brightness with fire.
Total depth · Ideal
66.1% 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 1.43:1 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: 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 · Favorable
G 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
VS2 is typically eye-clean, though step cuts show inclusions more readily — worth a close look at the images.
Fluorescence · Ideal
None: no meaningful effect on appearance.

What to check on the exact stone

  • Step cuts show inclusions openly—is this VS2 diamond eye-clean through the table from about 10 inches away?
  • 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?
