1.50 ct Round Brilliant Diamond

What reads well

• The GIA Excellent cut grade corroborates the measured proportions.
• Excellent polish and symmetry, the top finish grades.
• H color should face up white in most settings.
• Slightly thick girdle balances durability and weight retention.

What deserves a closer look

• Crown 34.5° / pavilion 41.6° fall outside the pairing zone associated with strong light return.
• Table 61% sits outside the preferred round range.

What to check on the exact stone

• Does the center turn dark or lose sparkle when you tilt the diamond face-up?
• Does the large table look bright but flat, with less colored fire than you expected?
• Does the feather reach the outer edge where a setting prong could put pressure on it?
• Can I view this stone in daylight to see if the blue fluorescence helps it look whiter?
