The Carat Standard

GIA report 7523718171

3.00 ct Cushion 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 cushion range.
  • Excellent polish and symmetry, the top finish grades.
  • G color should face up white in most settings.
  • VVS1 clarity: inclusions are not a practical visual factor.

What deserves a closer look

  • 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: 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 60%, the table sits within the typical 56–66% range for a cushion, balancing brightness with fire.
Total depth · Closer look
69.5% 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 1.02:1 outline is within the classic 1–1.35:1 range for a cushion.
Polish · Ideal
Excellent polish is the top finish grade — facets are cleanly executed with nothing that would soften sparkle.
Symmetry · Ideal
Excellent symmetry is the top finish grade — facets are cleanly executed with nothing that would soften sparkle.
Girdle · Closer look
Thick to very 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 · Favorable
G is near-colorless and faces up white in most settings.
Clarity · Ideal
VVS1: inclusions, if any, are only visible under magnification.
Fluorescence · Favorable
Medium Blue fluorescence is rarely visible in normal lighting.

What to check on the exact stone

  • With 69.5% depth, does this stone face up smaller than a typical 3.00 ct cushion?
  • Does the feather reach the outer edge where a setting prong could put pressure on it?
  • Does this cushion produce broad, chunky flashes or small needle-like crushed-ice sparkle?
  • Can you show me the inscribed report number under a loupe before it is set?
