1.01 ct Cushion Diamond

What reads well

• A 1.03:1 length-to-width ratio sits in the classic cushion range.
• Face-up spread (5.91 × 5.73 mm) is typical or better for a 1.01 ct cushion.
• Table 66% and depth 66.5% fall in the typical cushion range.
• Excellent polish and symmetry, the top finish grades.
• F color is in the colorless range.

What deserves a closer look

• Thick to very thick girdle: a thick girdle carries hidden weight and can reduce face-up size (thicker points are common in fancy shapes).
• Screening only: for this cushion, check images or video of the exact stone for the facet pattern (bold, chunky flashes or finer "crushed ice") and any dark areas under the table.

The reading, field by field

Table · Ideal

At 66%, the table sits within the typical 56–66% range for a cushion, balancing brightness with fire.

Total depth · Ideal

66.5% is within the typical 61–69% range for a cushion, keeping weight where it contributes to face-up size and light return.

Length-to-width · Ideal

A 1.03:1 outline is within the classic 1–1.35:1 range for a cushion.

Polish · Ideal

Excellent polish is the top finish grade — facets are cleanly executed with nothing that would soften sparkle.

Symmetry · Ideal

Excellent symmetry is the top finish grade — facets are cleanly executed with nothing that would soften sparkle.

Girdle · Closer look

Thick to very thick (faceted): a thick girdle carries weight in the rim, so the stone can face up a little smaller for its carat weight. It is durable, though.

Culet · Ideal

None: no visible culet facet when viewed face-up.

Color · Ideal

F is in the colorless range and faces up white in any metal.

Clarity · Favorable

VS1 is typically eye-clean.

Fluorescence · Favorable

Medium Blue fluorescence is rarely visible in normal lighting.

What to check on the exact stone

• Does the feather reach the outer edge where a setting prong could put pressure on it?
• Does this cushion produce broad, chunky flashes or small needle-like crushed-ice sparkle?
• Is extra carat weight trapped in the thick girdle rim where it does not add finger presence?
• Can you show me the inscribed report number under a loupe before it is set?
