The Carat Standard

IGI report LG797643108

5.00 ct Oval Laboratory-Grown Diamond

87/100 · Refined

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

What reads well

  • Face-up spread (14.01 × 9.13 mm) is typical or better for a 5.00 ct oval.
  • Excellent polish and symmetry, the top finish grades.
  • F 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

  • A 1.53:1 length-to-width ratio is outside the classic oval range; the outline will look more elongated than typical.
  • A 64.3% depth is on the deep side for an oval; deeper pavilions are associated with a stronger bow-tie and hidden weight.
  • Screening only: bow-tie, windowing and contrast in an oval 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 64.3% depth, does this stone face up smaller than a typical 5.00 ct oval?
  • How dark is the bow-tie shadow across the center when viewed in normal daylight?
  • 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?
