The Carat Standard

IGI report LG754594050

3.00 ct Square Cushion Laboratory-Grown Diamond

86/100 · Refined

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

What reads well

  • A 1.01:1 length-to-width ratio sits in the classic cushion range.
  • Table 57% and depth 68.4% fall in the typical cushion range.
  • Excellent polish and symmetry, the top finish grades.
  • D color is in the colorless range.
  • VVS1 clarity: inclusions are not a practical visual factor.

What deserves a closer look

  • Face-up area is about 12% below typical cushions of this weight, suggesting hidden weight in depth.
  • Thick to very thick girdle: a thick girdle carries hidden weight and can reduce face-up size (thicker points are common in fancy shapes).
  • Screening only: bow-tie, windowing and contrast in a cushion can only be judged from images or video of this exact stone.

What to check on the exact stone

  • Does this cushion produce broad, chunky flashes or small needle-like crushed-ice sparkle?
  • Is extra carat weight trapped in the thick girdle rim where it does not add finger presence?
  • Does this HPHT-grown diamond look neutral white beside another stone in daylight, with no gray or blue cast?
  • Can you show me the inscribed report number under a loupe before it is set?
