3.00 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 in a round brilliant usually faces up near-colorless once set.
• No fluorescence: no haze risk to weigh.
• Medium to slightly thick girdle balances durability and weight retention.

What deserves a closer look

• Crown 36.5° / pavilion 41° fall outside the pairing zone associated with strong light return.
• Depth 63.5% sits outside the preferred round range.
• Confirm this SI1 round brilliant is eye-clean from an image or video; the report plot shows where inclusions sit.
• Feathers are listed: check the plot for any that reach the girdle or surface, which matters for durability.

What to check on the exact stone

• Does the steep crown give lively fire without making the center look darker?
• With 63.5% depth, does this stone face up smaller than a typical 3.00 ct round?
• Does the feather reach the outer edge where a setting prong could put pressure on it?
• Is this SI1 diamond eye-clean face-up from about 10 inches away?
