The Carat Standard

GIA report 2457348285

1.00 ct Cushion Diamond

72/100 · Character

Distinctive trade-offs that should be viewed deliberately.

What reads well

  • A 1.06:1 length-to-width ratio sits in the classic cushion range.
  • 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

  • The depth 75.9% sits outside the typical cushion range.
  • Face-up area is about 21% below typical cushions of this weight, suggesting hidden weight in depth.
  • Very Good polish / Good symmetry is below the Excellent/Very Good standard and can soften sparkle.
  • Thick to extremely thick girdle: a thick girdle carries hidden weight and can reduce face-up size.
  • 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

  • With 75.9% depth, does this stone face up smaller than a typical 1.00 ct cushion?
  • 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?
  • With Very Good polish and Good symmetry, are there visible misaligned facets or wheel marks?
