The Carat Standard

IGI report LG832604037

1.00 ct Princess Laboratory-Grown Diamond

84/100 · 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 (5.55 × 5.42 mm) is typical or better for a 1.00 ct princess.
  • Table 74% and depth 69.6% fall in the typical princess range.
  • D color is in the colorless range.
  • VVS2 clarity: inclusions are not a practical visual factor.

What deserves a closer look

  • Very Good polish / Good symmetry is below the Excellent/Very Good standard and can soften sparkle.
  • 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

  • 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 polish and Good symmetry, are there visible misaligned facets or wheel marks?
  • Can you show me the inscribed report number under a loupe before it is set?
