4.01 ct Marquise Laboratory-Grown Diamond

What reads well

• A 2.00:1 length-to-width ratio sits in the classic marquise range.
• Face-up spread (16.48 × 8.26 mm) is typical or better for a 4.01 ct marquise.
• Table 59% and depth 63.9% fall in the typical marquise range.
• Excellent polish and symmetry, the top finish grades.
• VVS2 clarity: inclusions are not a practical visual factor.

What deserves a closer look

• The report says this stone may include post-growth treatment; ask the seller to confirm whether it is as-grown.
• G color in a 4.01 ct marquise may show some warmth, especially at the points.
• Screening only: for this marquise, check images or video of the exact stone for the bow-tie and whether the two points line up end to end.

What to check on the exact stone

• In a face-up video, does the bow-tie flicker as the stone tilts, or stay a fixed dark band across the center?
• Will the ring setting use protective V-tip prongs or a bezel to safeguard the two delicate points?
• 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?
