5.00 ct Marquise Laboratory-Grown Diamond

83/100 · Considered

A balanced profile with a few questions to carry forward.

What reads well

A 55.6% depth is shallow for a marquise; check images for a see-through window in the centre.
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 · Closer look: A 64% table is larger than typical for a marquise (53–63%). Large tables can read bright but flatter, with less fire and contrast.
Total depth · Closer look: 55.6% is shallower than typical for a marquise (58–64%). That spreads the stone face-up but raises the risk of windowing — a glassy, see-through center.
Length-to-width · Ideal: A 2.02:1 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 · Ideal: Medium to slightly thick (faceted): a durable girdle thickness that doesn't hide meaningful weight.
Culet · Ideal: Pointed: no visible culet facet when viewed face-up.
Color · Ideal: E is in the colorless range and faces up white in any metal.
Clarity · Favorable: VS2 is typically eye-clean.
Fluorescence · Ideal: None: no meaningful effect on appearance.

With a shallow 55.6% depth, can you see a glassy, see-through patch in the center?
Does the large table look bright but flat, with less colored fire than you expected?
Is this VS2 diamond eye-clean face-up from about 10 inches away?
Can you show me the inscribed report number under a loupe before it is set?
