IGI report LG729571581
1.02 ct Oval Laboratory-Grown Diamond
89/100 · Refined
A strong candidate on paper; confirm its light pattern in imagery.
What reads well
- A 1.42:1 length-to-width ratio sits in the classic oval range.
- Face-up spread (7.98 × 5.62 mm) is typical or better for a 1.02 ct oval.
- Excellent polish and symmetry, the top finish grades.
- E color is in the colorless range.
- VVS1 clarity: inclusions are not a practical visual factor.
What deserves a closer look
- A 64.1% depth is on the deep side for an oval; deeper pavilions are associated with a stronger bow-tie and hidden weight.
- 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.
What to check on the exact stone
- With 64.1% depth, does this stone face up smaller than a typical 1.02 ct oval?
- In a face-up video, does the bow-tie flicker as the stone tilts, or stay a fixed dark band across the center?
- Does this HPHT-grown diamond look neutral white beside another stone in daylight, with no gray or blue cast?
- Can you show me the inscribed report number under a loupe before it is set?
