The Carat Standard

GIA report 2121957591

1.01 ct Round Brilliant Diamond

93/100 · Signature

An unusually disciplined report profile.

What reads well

  • Table 57% and depth 62.3% are within the classic round brilliant range.
  • The GIA Excellent cut grade corroborates the measured proportions.
  • Excellent polish and symmetry, the top finish grades.
  • D color is in the colorless range.
  • VVS1 clarity: inclusions are not a practical visual factor.

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?
  • Can you confirm the stone's weight and measurements match the GIA report before it is set?
