1.50 ct Marquise Diamond

What reads well

• A 1.92:1 length-to-width ratio sits in the classic marquise range.
• Face-up spread (11.38 × 5.92 mm) is typical or better for a 1.50 ct marquise.
• Table 61% and depth 62.7% fall in the typical marquise range.
• 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 marquise; view an image or video of this exact stone.
• Clouds are referenced on the report; confirm the stone looks transparent rather than hazy.
• Surface-reaching characteristics are listed (cavity); check their position on the plot for durability.
• 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 marquise can only be judged from images or video of this exact stone.

What to check on the exact stone

• Does the diamond look crisp and transparent in natural light, or is there any milky haze?
• Does the feather reach the outer edge where a setting prong could put pressure on it?
• Is the surface opening protected by a prong, or could it catch lint and risk chipping?
• Will the ring setting use protective V-tip prongs or a bezel to safeguard the two delicate points?
