GIA report 7558097548
1.00 ct Cushion Diamond
79/100 · Considered
A balanced profile with a few questions to carry forward.
What reads well
- A 1.03:1 length-to-width ratio sits in the classic cushion range.
- F color is in the colorless range.
- No fluorescence: no haze risk to weigh.
What deserves a closer look
- Clouds are referenced on the report; confirm the stone looks transparent rather than hazy.
- Face-up area is about 19% below typical cushions of this weight, suggesting hidden weight in depth.
- Confirm this SI1 cushion is eye-clean from an image or video; the report plot shows where inclusions sit.
- Thick 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 69.5% depth, does this stone face up smaller than a typical 1.00 ct cushion?
- 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?
- Does this cushion produce broad, chunky flashes or small needle-like crushed-ice sparkle?
