A strong candidate on paper; confirm its light pattern in imagery.
What reads well
- A 1.05:1 length-to-width ratio sits in the classic princess range.
- Face-up spread (8.99 × 8.58 mm) is typical or better for a 4.09 ct princess.
- Table 70% and depth 70% fall in the typical princess range.
- Excellent polish and symmetry, the top finish grades.
- E color is in the colorless range.
What deserves a closer look
- Screening only: for this princess, check images or video of the exact stone for dark areas across the corners or a see-through centre.
- 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
- Will all four sharp corners be seated safely in V-prongs to prevent corner fractures?
- 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?
