GIA report 1529926037
3.00 ct Cushion Diamond
86/100 · Refined
A strong candidate on paper; confirm its light pattern in imagery.
What reads well
- A 1.02:1 length-to-width ratio sits in the classic cushion range.
- Excellent polish and symmetry, the top finish grades.
- G color should face up white in most settings.
What deserves a closer look
- Surface-reaching characteristics are listed (knot); check their position on the plot for durability.
- Strong blue fluorescence in a G-color stone: a small share of such stones look hazy in sunlight. View it in daylight and neutral light.
- The report notes internal graining; these can soften transparency in some stones.
- 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 61%, the table sits within the typical 56–66% range for a cushion, balancing brightness with fire.
- Total depth · Closer look
- 69.4% 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 1.02:1 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 · Ideal
- Excellent symmetry is the top finish grade — facets are cleanly executed with nothing that would soften sparkle.
- Girdle · Ideal
- Slightly thick to thick, faceted: a durable girdle thickness that doesn't hide meaningful weight.
- Culet · Ideal
- None: no visible culet facet when viewed face-up.
- Color · Favorable
- G is near-colorless and faces up white in most settings.
- Clarity · Favorable
- VS2 is typically eye-clean.
- Fluorescence · Closer look
- Strong Blue fluorescence in a G stone occasionally causes a slight haze in sunlight. View it in daylight before buying.
What to check on the exact stone
- With 69.4% depth, does this stone face up smaller than a typical 3.00 ct cushion?
- Does the diamond look crisp and transparent in natural light, or is there any milky haze?
- Is the surface opening protected by a prong, or could it catch lint and risk chipping?
- Can you show me the inscribed report number under a loupe before it is set?
