The Carat Standard

GCAL report 362396178

3.22 ct Round Brilliant Laboratory-Grown Diamond

90/100 · Refined

A strong, composed candidate on paper.

What reads well

  • Crown 34.5° with pavilion 40.8° sits in the well-regarded pairing zone for brightness and fire.
  • Table 56% and depth 62% are within the classic round brilliant range.
  • D color is in the colorless range.
  • VVS1 clarity: inclusions are not a practical visual factor.
  • No fluorescence: no haze risk to weigh.

What deserves a closer look

  • 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: cut grade, polish, symmetry. These are not assumed to be favorable, and confidence is lower.

The reading, field by field

Table · Ideal
At 56%, the table sits within the typical 53–59% range for a round brilliant, balancing brightness with fire.
Total depth · Ideal
62% is within the typical 59.5–63% range for a round brilliant, keeping weight where it contributes to face-up size and light return.
Crown angle · Ideal
34.5° sits in the 32–36° zone where crown angles typically balance fire and brightness.
Pavilion angle · Ideal
40.8° is inside the narrow 40.5–41.3° zone where the pavilion returns light most efficiently.
Girdle · Ideal
Medium - sl. thick, faceted: 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 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 GCAL report before it is set?
