A strong candidate on paper; confirm its light pattern in imagery.
What reads well
- A 2.00:1 length-to-width ratio sits in the classic marquise range.
- Face-up spread (14.91 × 7.44 mm) is typical or better for a 3.00 ct marquise.
- Table 59% and depth 63.7% fall in the typical marquise 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 a marquise 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
- Will the ring setting use protective V-tip prongs or a bezel to safeguard the two delicate points?
- 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?
