The Carat Standard

IGI report LG826615109

4.00 ct Pear Laboratory-Grown Diamond

82/100 · Considered

A balanced profile with a few questions to carry forward.

What reads well

  • 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 55.8% depth is shallow for a step cut; check images for a see-through window in the centre.
  • Screening only: windowing, contrast and the step-cut "hall of mirrors" pattern in a step 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 a shallow 55.8% depth, can you see a glassy, see-through patch in the center?
  • Will the ring setting use a protective V-tip prong or bezel to safeguard the delicate point?
  • 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?
