GIA report 7542945038
0.71 ct Oval Diamond
87/100 · Refined
A strong candidate on paper; confirm its light pattern in imagery.
What reads well
- A 1.40:1 length-to-width ratio sits in the classic oval range.
- Face-up spread (7.01 × 5.02 mm) is typical or better for a 0.71 ct oval.
- 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.
- Confirm this SI1 oval is eye-clean from an image or video; the report plot shows where inclusions sit.
- 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.
- Not stated on the report: culet. This is not assumed to be favorable, and confidence is lower.
The reading, field by field
- Table · Ideal
- At 62%, the table sits within the typical 53–63% range for an oval, balancing brightness with fire.
- Total depth · Closer look
- 63.6% 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 1.4:1 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 · Favorable
- Very Good symmetry is a fine result; the difference from Excellent is rarely visible without magnification.
- Girdle · Ideal
- Slightly thick to thick (faceted): a durable girdle thickness that doesn't hide meaningful weight.
- Color · Ideal
- F is in the colorless range and faces up white in any metal.
- Clarity · Favorable
- SI1 is often eye-clean in an oval, but not always — check where the inclusions sit.
- Fluorescence · Ideal
- None: no meaningful effect on appearance.
What to check on the exact stone
- With 63.6% depth, does this stone face up smaller than a typical 0.71 ct oval?
- Is this SI1 diamond eye-clean face-up from about 10 inches away?
- 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?
