IGI report LG729572110
3.07 ct Emerald Laboratory-Grown Diamond
89/100 · Refined
A strong candidate on paper; confirm its light pattern in imagery.
What reads well
- Face-up spread (10.04 × 6.62 mm) is typical or better for a 3.07 ct emerald cut.
- Table 68% and depth 68.9% fall in the typical emerald cut range.
- Excellent polish and symmetry, the top finish grades.
- E color is in the colorless range.
- VVS1 clarity: inclusions are not a practical visual factor.
What deserves a closer look
- A 1.52:1 length-to-width ratio is outside the classic emerald cut range; the outline will look more elongated than typical.
- 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.
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?
