The Carat Standard

IGI report LG823690346

3.00 ct Radiant Laboratory-Grown Diamond

35/100 · Investigate

The report asks for a more careful visual review.

What reads well

  • A 1.30:1 length-to-width ratio sits in the classic radiant 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.

What deserves a closer look

  • The table 55% and depth 82% sit outside the typical radiant range.
  • Face-up area is about 11% below typical radiants of this weight, suggesting hidden weight in depth.
  • Thick to very thick girdle: a thick girdle carries hidden weight and can reduce face-up size (thicker points are common in fancy shapes).
  • Screening only: bow-tie, windowing and contrast in a radiant 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 82% depth, does this stone face up smaller than a typical 3.00 ct cut?
  • Is extra carat weight trapped in the thick girdle rim where it does not add finger presence?
  • 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?
