The Carat Standard

GIA report 6341032381

1.50 ct Radiant Diamond

78/100 · Considered

A balanced profile with a few questions to carry forward.

What reads well

  • A 1.25:1 length-to-width ratio sits in the classic radiant range.
  • VVS1 clarity: inclusions are not a practical visual factor.
  • Very Strong blue fluorescence can make I color face up a touch whiter in daylight.

What deserves a closer look

  • The depth 72.7% sits outside the typical radiant range.
  • Face-up area is about 16% below typical radiants of this weight, suggesting hidden weight in depth.
  • Very thick girdle: a thick girdle carries hidden weight and can reduce face-up size (thicker points are common in fancy shapes).
  • I color in a 1.50 ct radiant may show some warmth, especially at the corners.
  • Screening only: bow-tie, windowing and contrast in a radiant can only be judged from images or video of this exact stone.

What to check on the exact stone

  • With 72.7% depth, does this stone face up smaller than a typical 1.50 ct cut-cornered?
  • Does the feather reach the outer edge where a setting prong could put pressure on it?
  • Can I view this stone in daylight to see if the blue fluorescence helps it look whiter?
  • Is extra carat weight trapped in the thick girdle rim where it does not add finger presence?
