1.50 ct Round Brilliant Diamond

What reads well

• Crown 36° with pavilion 40.8° sits in the well-regarded pairing zone for brightness and fire.
• The GIA Excellent cut grade corroborates the measured proportions.
• Excellent polish and symmetry, the top finish grades.
• H color should face up white in most settings.
• No fluorescence: no haze risk to weigh.

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.
• Surface-reaching characteristics are listed (cavity); check their position on the plot for durability.
• Feathers are listed: check the plot for any that reach the girdle or surface, which matters for durability.
• The report notes surface graining; these can soften transparency in some stones.

What to check on the exact stone

• Can I see this stone in soft daylight away from store spotlights to verify its sparkle?
• Does the sparkle look bright and even all the way out to the edges?
• 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?
