The Carat Standard

GIA report 2556525235

3.00 ct Round Brilliant Diamond

87/100 · 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.
  • H color in a round brilliant usually faces up near-colorless once set.
  • No fluorescence: no haze risk to weigh.

What deserves a closer look

  • Clouds are referenced on the report; confirm the stone looks transparent rather than hazy.
  • Confirm this SI1 round brilliant is eye-clean from an image or video; the report plot shows where inclusions sit.
  • Feathers are listed: check the plot for any that reach the girdle or surface, which matters for durability.
  • The report notes surface graining; these can soften transparency in some stones.

What to check on the exact stone

  • Does the steep crown give lively fire without making the center look darker?
  • Does the feather reach the outer edge where a setting prong could put pressure on it?
  • Is this SI1 diamond eye-clean face-up from about 10 inches away?
  • Can you show me the inscribed report number under a loupe before it is set?
