4.00 ct Cushion Diamond

What reads well

• A 1.31:1 length-to-width ratio sits in the classic cushion range.
• Face-up spread (11.01 × 8.39 mm) is typical or better for a 4.00 ct cushion.
• G color should face up white in most settings.
• VS1 clarity is typically eye-clean in a cushion.
• Faint fluorescence: no haze risk to weigh.

What deserves a closer look

• The table 68% sits outside the typical cushion range.
• Slightly 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 · Closer look

A 68% table is larger than typical for a cushion (56–66%). Large tables can read bright but flatter, with less fire and contrast.

Total depth · Closer look

69.3% 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 1.31:1 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 · Favorable

Very Good symmetry is a fine result; the difference from Excellent is rarely visible without magnification.

Girdle · Closer look

Slightly 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 · Favorable

G is near-colorless and faces up white in most settings.

Clarity · Favorable

VS1 is typically eye-clean.

Fluorescence · Ideal

Faint: no meaningful effect on appearance.

What to check on the exact stone

• With 69.3% depth, does this stone face up smaller than a typical 4.00 ct cushion?
• Does the large table look bright but flat, with less colored fire than you expected?
• Does the feather reach the outer edge where a setting prong could put pressure on it?
• Can you show me the inscribed report number under a loupe before it is set?
