The Carat Standard

IGI report LG831619182

1.50 ct Pear Laboratory-Grown Diamond

86/100 · Refined

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

What reads well

  • A 1.68:1 length-to-width ratio sits in the classic pear 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 66% sits outside the typical pear range.
  • Face-up area is unusually large for the weight, which can indicate a shallow cut with a see-through window.
  • Screening only: bow-tie, windowing and contrast in a pear 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

  • Does the large table look bright but flat, with less colored fire than you expected?
  • 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?
