The Carat Standard

GIA report 2528852532

1.50 ct Emerald Diamond

82/100 · Considered

A balanced profile with a few questions to carry forward.

What reads well

  • A 1.34:1 length-to-width ratio sits in the classic emerald cut range.
  • G color should face up white in most settings.
  • No fluorescence: no haze risk to weigh.

What deserves a closer look

  • Face-up area is about 14% below typical emerald cuts of this weight, suggesting hidden weight in depth.
  • Surface-reaching characteristics are listed (cavity); check their position on the plot for durability.
  • Thick to very thick girdle: a thick girdle carries hidden weight and can reduce face-up size (thicker points are common in fancy shapes).
  • The report notes internal graining; these can soften transparency in some stones.
  • Screening only: windowing, contrast and the step-cut "hall of mirrors" pattern in an emerald cut can only be judged from images or video of this exact stone.

What to check on the exact stone

  • With 69.3% depth, does this stone face up smaller than a typical 1.50 ct emerald?
  • Is the surface opening protected by a prong, or could it catch lint and risk chipping?
  • With open step facets, is the center completely eye-clean without any visible dark marks?
  • Is extra carat weight trapped in the thick girdle rim where it does not add finger presence?
