IGI report LG685560546
4.05 ct Oval Laboratory-Grown Diamond
93/100 · Signature
An unusually disciplined report profile.
What reads well
- A 1.42:1 length-to-width ratio sits in the classic oval range.
- Face-up spread (12.98 × 9.11 mm) is typical or better for a 4.05 ct oval.
- Table 60% and depth 61.6% fall in the typical oval range.
- Excellent polish and symmetry, the top finish grades.
- D color is in the colorless range.
What deserves a closer look
- 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
- 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?
