IGI report LG788614060
1.00 ct Pear Laboratory-Grown Diamond
89/100 · Refined
A strong candidate on paper; confirm its light pattern in imagery.
What reads well
- A 1.69:1 length-to-width ratio sits in the classic pear range.
- Face-up spread (9.30 × 5.50 mm) is typical or better for a 1.00 ct pear.
- E color is in the colorless range.
- VVS2 clarity: inclusions are not a practical visual factor.
- No fluorescence: no haze risk to weigh.
What deserves a closer look
- The table 66% sits outside the typical pear range.
- 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.
The reading, field by field
- Table · Closer look
- A 66% table is larger than typical for a pear (53–63%). Large tables can read bright but flatter, with less fire and contrast.
- Total depth · Ideal
- 61.5% is within the typical 58–64% range for a pear, keeping weight where it contributes to face-up size and light return.
- Length-to-width · Ideal
- A 1.69:1 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 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 · Ideal
- VVS2: inclusions, if any, are only visible under magnification.
- Fluorescence · Ideal
- None: no meaningful effect on appearance.
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 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?
