IGI report LG825635791
1.50 ct Emerald Laboratory-Grown Diamond
86/100 · 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.
- E color is in the colorless range.
- VVS2 clarity: inclusions are not a practical visual factor.
- No fluorescence: no haze risk to weigh.
- Slightly thick girdle balances durability and weight retention.
What deserves a closer look
- A 71% table is very large for a step cut, which can flatten the hall-of-mirrors effect.
- 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
- Can you see straight through the center (windowing), or does it reflect clean steps?
- 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?
- With Very Good polish and Very Good symmetry, are there visible misaligned facets or wheel marks?
