89/100 · Refined
A strong candidate on paper; confirm its light pattern in imagery.
What reads well
- A 1.44:1 length-to-width ratio sits in the classic oval range.
- Face-up spread (12.80 × 8.88 mm) is typical or better for a 4.00 ct oval.
- Table 60% and depth 63.3% fall in the typical oval range.
- Excellent polish and symmetry, the top finish grades.
- E color is in the colorless range.
What deserves a closer look
- Screening only: bow-tie, windowing and contrast in an oval can only be judged from images or video of this exact stone.
- 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
- How dark is the bow-tie shadow across the center when viewed in normal daylight?
- Does this CVD diamond show any brown or gray undertone face-up in daylight?
- Can you show me the inscribed report number under a loupe before it is set?
