1.50 ct Cushion Diamond

What reads well

• A 1.23:1 length-to-width ratio sits in the classic cushion range.
• Face-up spread (7.50 × 6.11 mm) is typical or better for a 1.50 ct cushion.
• VS1 clarity is typically eye-clean in a cushion.

What deserves a closer look

• The table 68% sits outside the typical cushion range.
• Medium to very thick girdle: a thick girdle carries hidden weight and can reduce face-up size (thicker points are common in fancy shapes).
• H color in a 1.50 ct cushion may show some warmth, especially at the corners.
• 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 · Ideal

68% 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 1.23:1 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

Medium 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

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

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 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 I view this stone in daylight to see if the blue fluorescence helps it look whiter?
• Can you show me the inscribed report number under a loupe before it is set?
