GIA report 6555520407
1.50 ct Round Brilliant Diamond
92/100 · Signature
An unusually disciplined report profile.
What reads well
- Crown 34.5° with pavilion 40.6° sits in the well-regarded pairing zone for brightness and fire.
- Table 59% and depth 61.6% are within the classic round brilliant range.
- The GIA Excellent cut grade corroborates the measured proportions.
- G color should face up white in most settings.
- No fluorescence: no haze risk to weigh.
What deserves a closer look
- The report notes internal graining; these can soften transparency in some stones.
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?
- Does the feather reach the outer edge where a setting prong could put pressure on it?
- With Very Good symmetry, are any facet junctions visibly misaligned?
