GIA report 2517416193
1.50 ct Cushion Diamond
84/100 · Refined
A strong candidate on paper; confirm its light pattern in imagery.
What reads well
- A 1.06:1 length-to-width ratio sits in the classic cushion range.
- VVS1 clarity: inclusions are not a practical visual factor.
- No fluorescence: no haze risk to weigh.
What deserves a closer look
- Slightly thick to extremely thick girdle: a thick girdle carries hidden weight and can reduce face-up size.
- I color in a 1.50 ct cushion may show some warmth, especially at the corners.
- 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.
The reading, field by field
- Table · Ideal
- At 59%, the table sits within the typical 56–66% range for a cushion, balancing brightness with fire.
- Total depth · Closer look
- 69.5% is deeper than typical for a cushion (61–69%). Extra depth holds weight below the girdle, so the stone can face up smaller than its carat weight suggests.
- Length-to-width · Ideal
- A 1.06:1 outline is within the classic 1–1.35:1 range for a cushion.
- 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
- Slightly 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
- None: no visible culet facet when viewed face-up.
- Color · Favorable
- I may show slight warmth, especially next to white metal. Yellow or rose gold tends to complement it.
- Clarity · Ideal
- VVS1: inclusions, if any, are only visible under magnification.
- Fluorescence · Ideal
- None: no meaningful effect on appearance.
What to check on the exact stone
- With 69.5% 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?
- Does this cushion produce broad, chunky flashes or small needle-like crushed-ice sparkle?
- Can you show me the inscribed report number under a loupe before it is set?
