IGI report LG772674260

3.00 ct Asscher Laboratory-Grown Diamond

76/100 · Considered

A balanced profile with a few questions to carry forward.

What reads well

A 1.02:1 length-to-width ratio sits in the classic Asscher / square emerald range.
Excellent polish and symmetry, the top finish grades.
E color is in the colorless range.
VVS2 clarity: inclusions are not a practical visual factor.
No fluorescence: no haze risk to weigh.

Face-up area is about 13% below typical Asscher / square emeralds of this weight, suggesting hidden weight in depth.
A 71.3% depth is deep for a step cut: weight sits below the girdle and the stone faces up smaller.
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.
Treatment status is not stated on the report. For a laboratory-grown diamond, ask whether it is as-grown or post-growth treated.

With 71.3% depth, does this stone face up smaller than a typical 3.00 ct square?
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?
