The Carat Standard

GIA report 6224042937

1.50 ct Radiant Diamond

86/100 · Refined

A strong candidate on paper; confirm its light pattern in imagery.

What reads well

  • A 1.22:1 length-to-width ratio sits in the classic radiant range.
  • Face-up spread (7.28 × 5.97 mm) is typical or better for a 1.50 ct radiant.
  • VVS2 clarity: inclusions are not a practical visual factor.
  • Medium blue fluorescence can make I color face up a touch whiter in daylight.

What deserves a closer look

  • The table 72% sits outside the typical radiant range.
  • Thick to very thick girdle: a thick girdle carries hidden weight and can reduce face-up size (thicker points are common in fancy shapes).
  • I color in a 1.50 ct radiant may show some warmth, especially at the corners.
  • 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 · Ideal
66.6% is within the typical 61–68% range for a radiant, keeping weight where it contributes to face-up size and light return.
Length-to-width · Ideal
A 1.22:1 outline is within the classic 1.2–1.5:1 range for a radiant.
Polish · Ideal
Excellent polish is the top finish grade — facets are cleanly executed with nothing that would soften sparkle.
Symmetry · Favorable
Very Good symmetry is a fine result; the difference from Excellent is rarely visible without magnification.
Girdle · Closer look
Thick to very thick: a thick girdle carries weight in the rim, so the stone can face up a little smaller for its carat weight. It is durable, though.
Culet · Ideal
None: no visible culet facet when viewed face-up.
Color · Favorable
I may show slight warmth at the corners of a radiant, especially next to white metal. Yellow or rose gold tends to complement it.
Clarity · Ideal
VVS2: inclusions, if any, are only visible under magnification.
Fluorescence · Favorable
Medium Blue fluorescence is rarely visible in normal lighting.

What to check on the exact stone

  • Does the large table look bright but flat, with less colored fire than you expected?
  • Can I view this stone in daylight to see if the blue fluorescence helps it look whiter?
  • Is extra carat weight trapped in the thick girdle rim where it does not add finger presence?
  • Can you show me the inscribed report number under a loupe before it is set?
