GCAL report 360876046
3.22 ct Round Brilliant Laboratory-Grown Diamond
90/100 · Refined
A strong, composed candidate on paper.
What reads well
- Crown 35° with pavilion 40.8° sits in the well-regarded pairing zone for brightness and fire.
- Table 58% and depth 61.9% are within the classic round brilliant range.
- D color is in the colorless range.
- IF 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 58%, the table sits within the typical 53–59% range for a round brilliant, balancing brightness with fire.
- Total depth · Ideal
- 61.9% 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
- 35° 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
- Internally Flawless (IF): inclusions, if any, are only visible under magnification.
- Fluorescence · Ideal
- None: no meaningful effect on appearance.
What to check on the exact stone
- 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?
