1.06 ct Pear Laboratory-Grown Diamond

83/100 · Considered

A balanced profile with a few questions to carry forward.

What reads well

A 57.1% depth is shallow for a step cut; check images for a see-through window in the centre.
Screening only: for this step cut, check images or video of the exact stone for the "hall of mirrors" step pattern and any see-through window.
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 69%, the table sits within the typical 60–72% range for a step cut, balancing brightness with fire.
Total depth · Closer look: 57.1% is shallower than typical for a step cut (60–72%). That spreads the stone face-up but raises the risk of windowing — a glassy, see-through center.
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: Slightly thick to thick: a durable girdle thickness that doesn't hide meaningful weight.
Culet · Ideal: None: no visible culet facet when viewed face-up.
Color · Ideal: D is in the colorless range and faces up white in any metal.
Clarity · Ideal: VVS2: inclusions, if any, are only visible under magnification.
Fluorescence · Ideal: None: no meaningful effect on appearance.

With a shallow 57.1% 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 a protective V-tip prong or bezel to safeguard the delicate point?
Can you show me the inscribed report number under a loupe before it is set?
