GIA report 5556359780
1.50 ct Oval Diamond
70/100 · Character
Distinctive trade-offs that should be viewed deliberately.
What reads well
- A 1.39:1 length-to-width ratio sits in the classic oval range.
- Excellent polish and symmetry, the top finish grades.
- No fluorescence: no haze risk to weigh.
What deserves a closer look
- SI2 is often not eye-clean in an oval; view an image or video of this exact stone.
- Clouds are referenced on the report; confirm the stone looks transparent rather than hazy.
- A 64.7% depth is on the deep side for an oval; deeper pavilions are associated with a stronger bow-tie and hidden weight.
- Thin to extremely thick girdle: a thick girdle carries hidden weight and can reduce face-up size.
- 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 63%, the table sits within the typical 53–63% range for an oval, balancing brightness with fire.
- Total depth · Closer look
- 64.7% 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 1.39:1 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 · Closer look
- Thin 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 at the tips of an oval, especially next to white metal. Yellow or rose gold tends to complement it.
- Clarity · Closer look
- SI2: inclusions may be visible to the eye. Confirm with images or video before buying.
- Fluorescence · Ideal
- None: no meaningful effect on appearance.
What to check on the exact stone
- With 64.7% depth, does this stone face up smaller than a typical 1.50 ct oval?
- Does the diamond look crisp and transparent in natural light, or is there any milky haze?
- Does the feather reach the outer edge where a setting prong could put pressure on it?
- Can you show me the inscribed report number under a loupe before it is set?
