The Carat Standard

GIA report 6555520407

1.50 ct Round Brilliant Diamond

92/100 · Signature

An unusually disciplined report profile.

What reads well

  • Crown 34.5° with pavilion 40.6° sits in the well-regarded pairing zone for brightness and fire.
  • Table 59% and depth 61.6% are within the classic round brilliant range.
  • The GIA Excellent cut grade corroborates the measured proportions.
  • G color should face up white in most settings.
  • No fluorescence: no haze risk to weigh.

What deserves a closer look

  • The report notes internal graining; these can soften transparency in some stones.

What to check on the exact stone

  • Can I see this stone in soft daylight away from store spotlights to verify its sparkle?
  • Does the sparkle look bright and even all the way out to the edges?
  • Does the feather reach the outer edge where a setting prong could put pressure on it?
  • With Very Good symmetry, are any facet junctions visibly misaligned?
