1.50 ct Round Brilliant Diamond

What reads well

• H color should face up white in most settings.
• Faint fluorescence: no haze risk to weigh.

What deserves a closer look

• The GIA cut grade is Good: the lab's own assessment points to less brightness and fire than its top tier.
• Crown 39.5° / pavilion 40.8° fall outside the pairing zone associated with strong light return.
• Depth 66.6% sits outside the preferred round range.
• Thick to very thick girdle: a thick girdle carries hidden weight and can reduce face-up size.
• The diameter is small for 1.50 ct: weight is carried below the girdle rather than face-up.

What to check on the exact stone

• Does the steep crown give lively fire without making the center look darker?
• 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?
• Does the feather reach the outer edge where a setting prong could put pressure on it?
