The Carat Standard

GIA report 2517416193

1.50 ct Cushion Diamond

81/100 · Considered

A balanced profile with a few questions to carry forward.

What reads well

  • A 1.06:1 length-to-width ratio sits in the classic cushion range.
  • VVS1 clarity: inclusions are not a practical visual factor.
  • No fluorescence: no haze risk to weigh.

What deserves a closer look

  • Face-up area is about 17% below typical cushions of this weight, suggesting hidden weight in depth.
  • Slightly thick to extremely thick girdle: a thick girdle carries hidden weight and can reduce face-up size.
  • I color in a 1.50 ct cushion may show some warmth, especially at the corners.
  • 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 69.5% depth, does this stone face up smaller than a typical 1.50 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?
  • Is extra carat weight trapped in the thick girdle rim where it does not add finger presence?
