The Carat Standard

GIA report 12914968

3.00 ct Radiant Diamond

54/100 · Investigate

The report asks for a more careful visual review.

What reads well

  • A 1.29:1 length-to-width ratio sits in the classic radiant range.
  • No fluorescence: no haze risk to weigh.

What deserves a closer look

  • The table 72% and depth 80.3% sit outside the typical radiant range.
  • Face-up area is about 18% below typical radiants of this weight, suggesting hidden weight in depth.
  • Very Good polish / Good symmetry is below the Excellent/Very Good standard and can soften sparkle.
  • Extremely thin to extremely thick girdle: a very thin edge raises chipping risk.
  • Screening only: for this radiant, check images or video of the exact stone for the sparkle pattern (defined flashes or "crushed ice") and any dark or see-through corners.

The reading, field by field

Table · Closer look
A 72% table is larger than typical for a radiant (60–70%). Large tables can read bright but flatter, with less fire and contrast.
Total depth · Closer look
80.3% is deeper than typical for a radiant (61–68%). Extra depth holds weight below the girdle, so the stone can face up smaller than its carat weight suggests.
Length-to-width · Ideal
A 1.29:1 outline is within the classic 1.2–1.5:1 range for a radiant.
Polish · Favorable
Very Good polish is a fine result; the difference from Excellent is rarely visible without magnification.
Symmetry · Closer look
Good symmetry is below the grades most buyers target and can slightly soften crispness. Worth seeing the stone in person or on video.
Girdle · Closer look
Extremely thin to extremely thick: thin sections of girdle are more vulnerable to chipping. A setting that protects the edge is sensible.
Culet · Ideal
None: no visible culet facet when viewed face-up.
Color · Favorable
G is near-colorless and faces up white in most settings, though a radiant can show a hint of warmth at the corners.
Clarity · Ideal
VVS1: inclusions, if any, are only visible under magnification.
Fluorescence · Ideal
None: no meaningful effect on appearance.

What to check on the exact stone

  • With 80.3% depth, does this stone face up smaller than a typical 3.00 ct radiant?
  • Does the large table look bright but flat, with less colored fire than you expected?
  • Does the feather reach the outer edge where a setting prong could put pressure on it?
  • Can you show me the inscribed report number under a loupe before it is set?
