3.71 ct Marquise Laboratory-Grown Diamond

What reads well

• A 2.06:1 length-to-width ratio sits in the classic marquise range.
• Face-up spread (17.00 × 8.27 mm) is typical or better for a 3.71 ct marquise.
• VVS2 clarity: inclusions are not a practical visual factor.
• No fluorescence: no haze risk to weigh.
• Medium to slightly thick girdle balances durability and weight retention.

What deserves a closer look

• H color in a 3.71 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.
• 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

• With a shallow 57.6% depth, can you see a glassy, see-through patch in the center?
• 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?
• Can you show me the inscribed report number under a loupe before it is set?
