4.03 ct Cushion Laboratory-Grown Diamond

What reads well

• Face-up spread (11.53 × 8.33 mm) is typical or better for a 4.03 ct Old Mine cut.
• Table 55% and depth 62.7% fall in the typical Old Mine cut range.
• Excellent polish and symmetry, the top finish grades.
• D color is in the colorless range.
• VVS1 clarity: inclusions are not a practical visual factor.

What deserves a closer look

• A 1.38:1 length-to-width ratio is outside the classic Old Mine cut range; the outline will look more elongated than typical.
• Screening only: for this Old Mine cut, check images or video of the exact stone for the broad, chunky antique flash pattern and how the open culet looks face-up.
• Treatment status is not stated on the report. For a laboratory-grown diamond, ask whether it is as-grown or post-growth treated.
• Not stated on the report: culet. This is not assumed to be favorable, and confidence is lower.

What to check on the exact stone

• Does this cushion produce broad, chunky flashes or small needle-like crushed-ice sparkle?
• 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?
