The Carat Standard

IGI report LG839651311

3.00 ct Radiant Laboratory-Grown Diamond

86/100 · Refined

A strong candidate on paper; confirm its light pattern in imagery.

What reads well

  • A 1.40:1 length-to-width ratio sits in the classic radiant range.
  • D color is in the colorless range.
  • VVS2 clarity: inclusions are not a practical visual factor.
  • No fluorescence: no haze risk to weigh.
  • Medium girdle balances durability and weight retention.

What deserves a closer look

  • The depth 71.9% sits outside the typical radiant range.
  • 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 71.9% depth, does this stone face up smaller than a typical 3.00 ct cut?
  • Does this CVD diamond show any brown or gray undertone face-up in daylight?
  • With Very Good polish, are there visible surface polish lines or wheel marks?
  • Can you show me the inscribed report number under a loupe before it is set?
