IGI report LG836626543

1.05 ct Pear Laboratory-Grown Diamond

86/100 · Refined

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

What reads well

Confirm this SI1 pear is eye-clean from an image or video; the report plot shows where inclusions sit.
Screening only: for this pear, check images or video of the exact stone for the bow-tie, even shoulders and a point that lines up with the centre of the rounded 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 53%, the table sits within the typical 53–63% range for a pear, balancing brightness with fire.
Total depth · Closer look: 57% is shallower than typical for a pear (58–64%). That spreads the stone face-up but raises the risk of windowing — a glassy, see-through center.
Length-to-width · Ideal: A 1.61:1 outline is within the classic 1.45–1.75:1 range for a pear.
Polish · Favorable: Very Good polish is a fine result; the difference from Excellent is rarely visible without magnification.
Symmetry · Favorable: Very Good symmetry is a fine result; the difference from Excellent is rarely visible without magnification.
Girdle · Ideal: Medium to 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: F is in the colorless range and faces up white in any metal.
Clarity · Favorable: SI1 is often eye-clean in a pear, but not always — check where the inclusions sit.
Fluorescence · Ideal: None: no meaningful effect on appearance.

With a shallow 57% depth, can you see a glassy, see-through patch in the center?
Is this SI1 diamond eye-clean face-up from about 10 inches away?
In a face-up video, does the bow-tie flicker as the stone tilts, or stay a fixed dark band across the center?
Can you show me the inscribed report number under a loupe before it is set?
