IGI report LG825635764
1.50 ct Emerald Laboratory-Grown Diamond
83/100 · Considered
A balanced profile with a few questions to carry forward.
What reads well
- A 1.38:1 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.
What deserves a closer look
- Face-up area is about 13% below typical emerald cuts of this weight, suggesting hidden weight in depth.
- A 73% 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 73% depth, does this stone face up smaller than a typical 1.50 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?
- With Very Good polish and Very Good symmetry, are there visible misaligned facets or wheel marks?
