The Carat Standard

IGI report LG812607868

1.50 ct Princess Laboratory-Grown Diamond

88/100 · Refined

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

What reads well

  • A 1.02:1 length-to-width ratio sits in the classic princess range.
  • Face-up spread (6.33 × 6.19 mm) is typical or better for a 1.50 ct princess.
  • D 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 76% sits outside the typical princess range.
  • Screening only: bow-tie, windowing and contrast in a princess 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 all four sharp corners be seated safely in V-prongs to prevent corner fractures?
  • Does this CVD diamond show any brown or gray undertone face-up in daylight?
  • With Very Good symmetry, are any facet junctions visibly misaligned?
