What reads well

• Crown 34.6° with pavilion 40.7° sits in the well-regarded pairing zone for brightness and fire.

• Excellent polish and symmetry, the top finish grades.

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 this HPHT-grown diamond look neutral white beside another stone in daylight, with no gray or blue cast?
• Can you show me the inscribed report number under a loupe before it is set?
