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 11% 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: for this cushion, check images or video of the exact stone for the facet pattern (bold, chunky flashes or finer "crushed ice") and any dark areas under the table.

The reading, field by field

Table · Ideal
At 65%, the table sits within the typical 56–66% range for a cushion, balancing brightness with fire.
Total depth · Closer look
75.9% is deeper than typical for a cushion (61–69%). Extra depth holds weight below the girdle, so the stone can face up smaller than its carat weight suggests.
Length-to-width · Ideal
A 1.06:1 outline is within the classic 1–1.35:1 range for a cushion.
Polish · Favorable
Very Good polish is a fine result; the difference from Excellent is rarely visible without magnification.
Symmetry · Closer look
Good symmetry is below the grades most buyers target and can slightly soften crispness. Worth seeing the stone in person or on video.
Girdle · Closer look
Thick to extremely thick, faceted: a thick girdle carries weight in the rim, so the stone can face up a little smaller for its carat weight. It is durable, though.
Culet · Ideal
None: no visible culet facet when viewed face-up.
Color · Ideal
F is in the colorless range and faces up white in any metal.
Clarity · Ideal
VVS2: inclusions, if any, are only visible under magnification.
Fluorescence · Ideal
None: no meaningful effect on appearance.

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?
  • Can you show me the inscribed report number under a loupe before it is set?
