The Carat Standard

GIA report 5546974207

1.58 ct Round Brilliant Diamond

90/100 · 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.
  • F color is in the colorless range.
  • VVS2 clarity: inclusions are not a practical visual factor.
  • Slightly thick girdle balances durability and weight retention.

What deserves a closer look

  • Crown 33.5° / pavilion 41.6° fall outside the pairing zone associated with strong light return.

What to check on the exact stone

  • Does the center turn dark or lose sparkle when you tilt the diamond face-up?
  • 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?
