IGI report LG825657089
1.00 ct Asscher Laboratory-Grown Diamond
83/100 · Considered
A balanced profile with a few questions to carry forward.
What reads well
- A 1.05:1 length-to-width ratio sits in the classic Asscher / square emerald range.
- E color is in the colorless range.
- VVS2 clarity: inclusions are not a practical visual factor.
- No fluorescence: no haze risk to weigh.
- The report states no indication of post-growth treatment.
What deserves a closer look
- Face-up area is about 13% below typical Asscher / square emeralds of this weight, suggesting hidden weight in depth.
- A 74% 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 Asscher / square emerald can only be judged from images or video of this exact stone.
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 HPHT-grown diamond look neutral white beside another stone in daylight, with no gray or blue cast?
- With Very Good symmetry, are any facet junctions visibly misaligned?
