1.50 ct Round Brilliant Diamond

What reads well

• VVS2 clarity: inclusions are not a practical visual factor.
• I color in a round brilliant usually faces up near-colorless once set.
• 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 40° / pavilion 39.6° fall outside the pairing zone associated with strong light return.
• Depth 66.6% sits outside the preferred round range.
• 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 a gray ring or glassy patch show around the center when you look straight down?
• With 66.6% depth, does this stone face up smaller than a typical 1.50 ct round?
• Does the feather reach the outer edge where a setting prong could put pressure on it?
• Is extra carat weight trapped in the thick girdle rim where it does not add finger presence?
