1.00 ct Oval Diamond

What reads well

• A 1.35:1 length-to-width ratio sits in the classic oval range.
• Face-up spread (7.87 × 5.84 mm) is typical or better for a 1.00 ct oval.
• D color is in the colorless range.
• VS1 clarity is typically eye-clean in an oval.
• Faint fluorescence: no haze risk to weigh.

What deserves a closer look

• A 55.2% depth is shallow for an oval; check images for a see-through window in the centre.
• Slightly thick to very thick girdle: a thick girdle carries hidden weight and can reduce face-up size (thicker points are common in fancy shapes).
• 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.

What to check on the exact stone

• With a shallow 55.2% depth, can you see a glassy, see-through patch in the center?
• Does the feather reach the outer edge where a setting prong could put pressure on it?
• 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?
