The Carat Standard

GIA report 7556946092

1.50 ct Marquise Diamond

83/100 · Considered

A balanced profile with a few questions to carry forward.

What reads well

  • A 2.18:1 length-to-width ratio sits in the classic marquise range.
  • Table 61% and depth 58.8% fall in the typical marquise range.
  • Excellent polish and symmetry, the top finish grades.
  • No fluorescence: no haze risk to weigh.

What deserves a closer look

  • Slightly thick to very thick girdle: a thick girdle carries hidden weight and can reduce face-up size (thicker points are common in fancy shapes).
  • J color in a 1.50 ct marquise may show some warmth, especially at the points.
  • The report notes surface graining; these can soften transparency in some stones.
  • Screening only: bow-tie, windowing and contrast in a marquise can only be judged from images or video of this exact stone.

What to check on the exact stone

  • Does the feather reach the outer edge where a setting prong could put pressure on it?
  • Will the ring setting use protective V-tip prongs or a bezel to safeguard the two delicate points?
  • 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?
