The Carat Standard

GIA report 5526275312

3.00 ct Princess Diamond

76/100 · Considered

A balanced profile with a few questions to carry forward.

What reads well

  • A 1.01:1 length-to-width ratio sits in the classic princess range.
  • Table 69% and depth 74.7% fall in the typical princess range.
  • 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 princess is eye-clean from an image or video; the report plot shows where inclusions sit.
  • Excellent polish / Good symmetry is below the Excellent/Very Good standard and can soften sparkle.
  • Surface-reaching characteristics are listed (cavity); check their position on the plot for durability.
  • Screening only: bow-tie, windowing and contrast in a princess can only be judged from images or video of this exact stone.

What to check on the exact stone

  • Does the diamond look crisp and transparent in natural light, or is there any milky haze?
  • Does the feather reach the outer edge where a setting prong could put pressure on it?
  • Is the surface opening protected by a prong, or could it catch lint and risk chipping?
  • Is extra carat weight trapped in the thick girdle rim where it does not add finger presence?
