IGI report LG831653288
3.00 ct Emerald Laboratory-Grown Diamond
86/100 · Refined
A strong candidate on paper; confirm its light pattern in imagery.
What reads well
- A 1.39:1 length-to-width ratio sits in the classic 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.
- No fluorescence: no haze risk to weigh.
What deserves a closer look
- Face-up area is about 14% below typical emerald cuts of this weight, suggesting hidden weight in depth.
- A 70.1% depth is deep for a step cut: weight sits below the girdle and the stone faces up smaller.
- Screening only: windowing, contrast and the step-cut "hall of mirrors" pattern in an emerald cut can only be judged from images or video of this exact stone.
- 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 70.1% depth, does this stone face up smaller than a typical 3.00 ct emerald?
- 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?
