GIA report 6522715744
1.50 ct Oval Diamond
89/100 · Refined
A strong candidate on paper; confirm its light pattern in imagery.
What reads well
- A 1.39:1 length-to-width ratio sits in the classic oval range.
- Face-up spread (8.98 × 6.48 mm) is typical or better for a 1.50 ct oval.
- Table 63% and depth 62.7% fall in the typical oval range.
- D color is in the colorless range.
- Faint fluorescence: no haze risk to weigh.
What deserves a closer look
- The report notes surface 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 63%, the table sits within the typical 53–63% range for an oval, balancing brightness with fire.
- Total depth · Ideal
- 62.7% is within the typical 58–63.5% range for an oval, keeping weight where it contributes to face-up size and light return.
- 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 · Favorable
- Very Good symmetry is a fine result; the difference from Excellent is rarely visible without magnification.
- Girdle · Ideal
- Slightly thick - 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
- D is in the colorless range and faces up white in any metal.
- Clarity · Favorable
- VS2 is typically eye-clean.
- Fluorescence · Ideal
- Faint: no meaningful effect on appearance.
What to check on the exact stone
- Does the feather reach the outer edge where a setting prong could put pressure on it?
- Is this VS2 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?
