The Carat Standard

GIA report 2537181342

3.00 ct Round Brilliant Diamond

85/100 · 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.
  • Medium to slightly thick girdle balances durability and weight retention.

What deserves a closer look

  • Crown 36.5° / pavilion 41° fall outside the pairing zone associated with strong light return.
  • Depth 63.7% sits outside the preferred round range.
  • Surface-reaching characteristics are listed (etch channel); check their position on the plot for durability.
  • The report notes surface graining and internal graining; these can soften transparency in some stones.
  • Strong blue fluorescence: view the stone in daylight to confirm it is not hazy.

What to check on the exact stone

  • Does the steep crown give lively fire without making the center look darker?
  • With 63.7% depth, does this stone face up smaller than a typical 3.00 ct round?
  • Does the feather reach the outer edge where a setting prong could put pressure on it?
  • Is this VS2 diamond eye-clean face-up from about 10 inches away?
