4.00 ct Round Brilliant Laboratory-Grown Diamond

What reads well

• Crown 35.7° with pavilion 40.7° sits in the well-regarded pairing zone for brightness and fire.
• The IGI Excellent cut grade corroborates the measured proportions.
• Excellent polish and symmetry, the top finish grades.
• D color is in the colorless range.
• VVS2 clarity: inclusions are not a practical visual factor.

What deserves a closer look

• Treatment status is not stated on the report. For a laboratory-grown diamond, ask whether it is as-grown or post-growth treated.

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 CVD diamond show any brown or gray undertone face-up in daylight?
• Can you show me the inscribed report number under a loupe before it is set?
