GIA report 7551406177
3.50 ct Oval Diamond
89/100 · Refined
A strong candidate on paper; confirm its light pattern in imagery.
What reads well
- A 1.45:1 length-to-width ratio sits in the classic oval range.
- Face-up spread (12.05 × 8.30 mm) is typical or better for a 3.50 ct oval.
- Excellent polish and symmetry, the top finish grades.
- F color is in the colorless range.
- VVS2 clarity: inclusions are not a practical visual factor.
What deserves a closer look
- Strong blue fluorescence in a F-color stone: a small share of such stones look hazy in sunlight. View it in daylight and neutral light.
- Screening only: for this oval, check images or video of the exact stone for the bow-tie (a dark band across the centre) and whether both ends look even.
The reading, field by field
- Table · Ideal
- At 61%, the table sits within the typical 53–63% range for an oval, balancing brightness with fire.
- Total depth · Closer look
- 63.9% is deeper than typical for an oval (58–63.5%). Extra depth holds weight below the girdle, so the stone can face up smaller than its carat weight suggests and may show a stronger bow-tie.
- Length-to-width · Ideal
- A 1.45:1 outline is within the classic 1.3–1.5:1 range for an oval.
- 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
- Medium 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 · Ideal
- F is in the colorless range and faces up white in any metal.
- Clarity · Ideal
- VVS2: inclusions, if any, are only visible under magnification.
- Fluorescence · Closer look
- Strong Blue fluorescence in an F stone occasionally causes a slight haze in sunlight. View it in daylight before buying.
What to check on the exact stone
- With 63.9% depth, does this stone face up smaller than a typical 3.50 ct oval?
- Does this F diamond show any milky haze when viewed outdoors in direct sunlight?
- In a face-up video, does the bow-tie flicker as the stone tilts, or stay a fixed dark band across the center?
- Can you show me the inscribed report number under a loupe before it is set?
