1.04 ct Marquise Laboratory-Grown Diamond

88/100 · Refined

A strong candidate on paper; confirm its light pattern in imagery.

What reads well

A 65.1% depth is on the deep side for a marquise; deeper pavilions are associated with a stronger bow-tie and hidden weight.
Thick to very thick girdle: a thick girdle carries hidden weight and can reduce face-up size (thicker points are common in fancy shapes).
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.

Table · Ideal: At 60%, the table sits within the typical 53–63% range for a marquise, balancing brightness with fire.
Total depth · Closer look: 65.1% is deeper than typical for a marquise (58–64%). Extra depth holds weight below the girdle, so the stone can face up smaller than its carat weight suggests and may show a stronger bow-tie.
Length-to-width · Ideal: A 1.93:1 outline is within the classic 1.85–2.2:1 range for a marquise.
Polish · Ideal: Excellent polish is the top finish grade — facets are cleanly executed with nothing that would soften sparkle.
Symmetry · Ideal: Excellent symmetry is the top finish grade — facets are cleanly executed with nothing that would soften sparkle.
Girdle · Closer look: Thick to very thick (faceted): a thick girdle carries weight in the rim, so the stone can face up a little smaller for its carat weight. It is durable, though.
Culet · Ideal: Pointed: no visible culet facet when viewed face-up.
Color · Ideal: D is in the colorless range and faces up white in any metal.
Clarity · Favorable: VS1 is typically eye-clean.
Fluorescence · Ideal: None: no meaningful effect on appearance.

With 65.1% depth, does this stone face up smaller than a typical 1.04 ct marquise?
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?
