The Carat Standard

GCAL report 360756207

3.53 ct Radiant Laboratory-Grown Diamond

89/100 · Refined

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

What reads well

  • A 1.47:1 length-to-width ratio sits in the classic radiant range.
  • Face-up spread (11.07 × 7.53 mm) is typical or better for a 3.53 ct radiant.
  • Table 65% and depth 66.4% fall in the typical radiant range.
  • D color is in the colorless range.
  • VVS1 clarity: inclusions are not a practical visual factor.

What deserves a closer look

  • 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.
  • Treatment status is not stated on the report. For a laboratory-grown diamond, ask whether it is as-grown or post-growth treated.
  • Not stated on the report: polish, symmetry. These are not assumed to be favorable, and confidence is lower.

The reading, field by field

Table · Ideal
At 65%, the table sits within the typical 60–70% range for a radiant, balancing brightness with fire.
Total depth · Ideal
66.4% 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 1.47:1 outline is within the classic 1.2–1.5:1 range for a radiant.
Girdle · Ideal
Medium: a durable girdle thickness that doesn't hide meaningful weight.
Culet · Ideal
None: no visible culet facet when viewed face-up.
Color · Ideal
D is in the colorless range and faces up white in any metal.
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

  • Does the feather reach the outer edge where a setting prong could put pressure on it?
  • Can you confirm the stone's weight and measurements match the GCAL report before it is set?
