1.00 ct Round Brilliant Diamond

What reads well

• The GIA Excellent cut grade corroborates the measured proportions.
• Excellent polish and symmetry, the top finish grades.
• G color should face up white in most settings.
• Faint fluorescence: no haze risk to weigh.
• Medium to slightly thick girdle balances durability and weight retention.

What deserves a closer look

• Clouds are referenced on the report; confirm the stone looks transparent rather than hazy.
• 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 center turn dark or lose sparkle when you tilt the diamond face-up?
• Does the diamond look crisp and transparent in natural light, or is there any milky haze?
• Does the feather reach the outer edge where a setting prong could put pressure on it?
• Can you show me the inscribed report number under a loupe before it is set?
