1.50 ct Round Brilliant Diamond

What reads well

• D color is in the colorless range.

What deserves a closer look

• SI2 is often not eye-clean in a round brilliant; view an image or video of this exact stone.
• The GIA cut grade is Good: the lab's own assessment points to less brightness and fire than its top tier.
• Crown 39° / pavilion 42.4° fall outside the pairing zone associated with strong light return.
• Table 64% and depth 66.6% sit outside the preferred round range.
• Slightly thick to very thick girdle: a thick girdle carries hidden weight and can reduce face-up size.

What to check on the exact stone

• Does the center turn dark or lose sparkle when you tilt the diamond face-up?
• With 66.6% depth, does this stone face up smaller than a typical 1.50 ct round?
• Does the large table look bright but flat, with less colored fire than you expected?
• Is this SI2 diamond eye-clean face-up from about 10 inches away?
