The Carat Standard

GIA report 1509591914

1.50 ct Round Brilliant Diamond

88/100 · Refined

A strong, composed candidate on paper.

What reads well

  • The GIA Excellent cut grade corroborates the measured proportions.
  • Excellent polish and symmetry, the top finish grades.
  • G color should face up white in most settings.
  • VVS1 clarity: inclusions are not a practical visual factor.
  • No fluorescence: no haze risk to weigh.

What deserves a closer look

  • Crown 36.5° / pavilion 41.2° fall outside the pairing zone associated with strong light return.
  • Depth 63.3% sits outside the preferred round range.

What to check on the exact stone

  • Does the steep crown give lively fire without making the center look darker?
  • With 63.3% depth, does this stone face up smaller than a typical 1.50 ct round?
  • Does the feather reach the outer edge where a setting prong could put pressure on it?
  • Can you show me the inscribed report number under a loupe before it is set?
