IGI report LG830649121

3.00 ct Emerald Laboratory-Grown Diamond

87/100 · 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.
  • Excellent polish and symmetry, the top finish grades.
  • E color is in the colorless range.
  • VVS1 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 12% below typical emerald cuts of this weight, suggesting hidden weight in depth.
  • 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 69.8% depth, does this stone face up smaller than a typical 3.00 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?
  • Can you show me the inscribed report number under a loupe before it is set?
