IGI report LG779608550
3.54 ct Oval Laboratory-Grown Diamond
89/100 · Refined
A strong candidate on paper; confirm its light pattern in imagery.
What reads well
- A 1.50:1 length-to-width ratio sits in the classic oval range.
- Face-up spread (12.54 × 8.37 mm) is typical or better for a 3.54 ct oval.
- Excellent polish and symmetry, the top finish grades.
- D color is in the colorless range.
- VS1 clarity is typically eye-clean in an oval.
What deserves a closer look
- Slightly 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 oval, check images or video of the exact stone for the bow-tie (a dark band across the centre) and whether both ends look even.
- Treatment status is not stated on the report. For a laboratory-grown diamond, ask whether it is as-grown or post-growth treated.
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?
- Is extra carat weight trapped in the thick girdle rim where it does not add finger presence?
- Can you show me the inscribed report number under a loupe before it is set?
