1.51 ct Round Brilliant Diamond

What reads well

• Crown 36° with pavilion 40.8° sits in the well-regarded pairing zone for brightness and fire.
• Table 58% and depth 62.4% are within the classic round brilliant range.
• The GIA Excellent cut grade corroborates the measured proportions.
• Excellent polish and symmetry, the top finish grades.
• E color is in the colorless range.

What deserves a closer look

• Clouds are referenced on the report; confirm the stone looks transparent rather than hazy.
• Strong blue fluorescence in a E-color stone: a small share of such stones look hazy in sunlight. View it in daylight and neutral light.

What to check on the exact stone

• 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?
• Does this E diamond show any milky haze when viewed outdoors in direct sunlight?
• Can you show me the inscribed report number under a loupe before it is set?
