1.33 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 (11.66 × 5.66 mm) is typical or better for a 1.33 ct marquise.
• E color is in the colorless range.
• VS1 clarity is typically eye-clean in a marquise.
• No fluorescence: no haze risk to weigh.

What deserves a closer look

• 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

• Does the large table look bright but flat, with less colored fire than you expected?
• 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?
