1.01 ct Cushion Laboratory-Grown Diamond

What reads well

• A 1.35:1 length-to-width ratio sits in the classic cushion range.
• Face-up spread (6.74 × 5.01 mm) is typical or better for a 1.01 ct cushion.
• Excellent polish and symmetry, the top finish grades.
• E color is in the colorless range.
• VS1 clarity is typically eye-clean in a cushion.

What deserves a closer look

• The depth 71.1% sits outside the typical cushion range.
• 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.
• Treatment status is not stated on the report. For a laboratory-grown diamond, ask whether it is as-grown or post-growth treated.

The reading, field by field

Table · Ideal

At 63%, the table sits within the typical 56–66% range for a cushion, balancing brightness with fire.

Total depth · Closer look

71.1% is deeper than typical for a cushion (61–69%). Extra depth holds weight below the girdle, so the stone can face up smaller than its carat weight suggests.

Length-to-width · Ideal

A 1.35:1 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

Pointed: no visible culet facet when viewed face-up.

Color · Ideal

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

Clarity · Favorable

VS1 is typically eye-clean.

Fluorescence · Ideal

None: no meaningful effect on appearance.

What to check on the exact stone

• With 71.1% depth, does this stone face up smaller than a typical 1.01 ct cushion?
• 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?
