The Carat Standard

GIA report 2556685417

1.50 ct Asscher Diamond

77/100 · Considered

A balanced profile with a few questions to carry forward.

What reads well

  • A 1.02:1 length-to-width ratio sits in the classic Asscher / square emerald range.
  • Table 66% and depth 69.7% fall in the typical Asscher / square emerald range.
  • Excellent polish and symmetry, the top finish grades.
  • No fluorescence: no haze risk to weigh.

What deserves a closer look

  • SI1 in an Asscher / square emerald: the open step-cut table makes inclusions easier to see. View an image or video of this exact stone.
  • Clouds are referenced on the report; confirm the stone looks transparent rather than hazy.
  • Face-up area is about 13% below typical Asscher / square emeralds of this weight, suggesting hidden weight in depth.
  • 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: windowing, contrast and the step-cut "hall of mirrors" pattern in an Asscher / square emerald can only be judged from images or video of this exact stone.

What to check on the exact stone

  • Does the diamond look crisp and transparent in natural light, or is there any milky haze?
  • Does the feather reach the outer edge where a setting prong could put pressure on it?
  • 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?
