GIA report 7532975553
1.00 ct Oval Diamond
85/100 · 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.
- Excellent polish and symmetry, the top finish grades.
- G color should face up white in most settings.
What deserves a closer look
- Confirm this SI1 oval is eye-clean from an image or video; the report plot shows where inclusions sit.
- A 65% depth is on the deep side for an oval; deeper pavilions are associated with a stronger bow-tie and hidden weight.
- Feathers are listed: check the plot for any that reach the girdle or surface, which matters for durability.
- The report notes internal graining; these can soften transparency in some stones.
- 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 60%, the table sits within the typical 53–63% range for an oval, balancing brightness with fire.
- Total depth · Closer look
- 65% 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 · 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 · Favorable
- G is near-colorless and faces up white in most settings, though an oval can show a hint of warmth at the tips.
- Clarity · Favorable
- SI1 is often eye-clean in an oval, but not always — check where the inclusions sit.
- Fluorescence · Favorable
- Medium Blue fluorescence is rarely visible in normal lighting.
What to check on the exact stone
- With 65% depth, does this stone face up smaller than a typical 1.00 ct oval?
- Does the feather reach the outer edge where a setting prong could put pressure on it?
- Is this SI1 diamond eye-clean face-up from about 10 inches away?
- Can you show me the inscribed report number under a loupe before it is set?
