3.00 ct Cushion Diamond

What reads well

• A 1.07:1 length-to-width ratio sits in the classic cushion range.
• Table 60% and depth 67.9% fall in the typical cushion range.
• Excellent polish and symmetry, the top finish grades.

What deserves a closer look

• SI2 is often not eye-clean in a cushion; view an image or video of this exact stone.
• Face-up area is about 16% below typical cushions of this weight, suggesting hidden weight in depth.
• Surface-reaching characteristics are listed (cavity, knot); check their position on the plot for durability.
• Thin 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

• 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?
• Is this SI2 diamond eye-clean face-up from about 10 inches away?
• Can I view this stone in daylight to see if the blue fluorescence helps it look whiter?
