IGI report LG815642090
1.50 ct Asscher Laboratory-Grown Diamond
87/100 · Refined
A strong candidate on paper; confirm its light pattern in imagery.
What reads well
- A 1.00:1 length-to-width ratio sits in the classic Asscher / square emerald range.
- Face-up spread (6.45 × 6.45 mm) is typical or better for a 1.50 ct Asscher / square emerald.
- Excellent polish and symmetry, the top finish grades.
- D color is in the colorless range.
- VVS2 clarity: inclusions are not a practical visual factor.
What deserves a closer look
- The table 70% sits outside the typical Asscher / square emerald range.
- A 59.3% depth is shallow for an Asscher / square emerald; check images for a see-through window in the centre.
- 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.
- 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 a shallow 59.3% depth, can you see a glassy, see-through patch in the center?
- 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?
