1.50 ct Cushion Laboratory-Grown Diamond

What reads well

• Face-up spread (7.99 × 5.58 mm) is typical or better for a 1.50 ct cushion.
• Table 65% and depth 68.8% fall in the typical cushion range.
• D color is in the colorless range.
• VVS2 clarity: inclusions are not a practical visual factor.
• No fluorescence: no haze risk to weigh.

What deserves a closer look

• A 1.43:1 length-to-width ratio is outside the classic cushion range; the outline will look more elongated than typical.
• Thick to extremely thick girdle: a thick girdle carries hidden weight and can reduce face-up size.
• 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 65%, the table sits within the typical 56–66% range for a cushion, balancing brightness with fire.

Total depth · Ideal

68.8% 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 · Favorable

A 1.43:1 outline is longer and slimmer than the classic 1–1.35:1 range for a cushion — a matter of taste, but worth seeing in person.

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

Thick to extremely 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

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

Clarity · Ideal

VVS2: inclusions, if any, are only visible under magnification.

Fluorescence · Ideal

None: no meaningful effect on appearance.

What to check on the exact stone

• 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?
• 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?
