1.50 ct Cushion Diamond

What reads well

• Excellent polish and symmetry, the top finish grades.
• Faint fluorescence: no haze risk to weigh.

What deserves a closer look

• SI2 is often not eye-clean in a cushion; view an image or video of this exact stone.
• A 1.27:1 length-to-width ratio is outside the classic cushion range; the outline will look more elongated than typical.
• Face-up area is about 11% below typical cushions of this weight, suggesting hidden weight in depth.
• Medium 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: bow-tie, windowing and contrast in a cushion can only be judged from images or video of this exact stone.

What to check on the exact stone

• With 69.7% depth, does this stone face up smaller than a typical 1.50 ct cushion?
• Does the feather reach the outer edge where a setting prong could put pressure on it?
• Is this SI2 diamond eye-clean face-up from about 10 inches away?
• Does this cushion produce broad, chunky flashes or small needle-like crushed-ice sparkle?
