1.00 ct Oval Diamond

82/100 · Considered

A balanced profile with a few questions to carry forward.

What reads well

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.

Table · Ideal: At 60%, the table sits within the typical 53–63% range for an oval, balancing brightness with fire.
Total depth · Closer look: 55.2% is shallower than typical for an oval (58–63.5%). That spreads the stone face-up but raises the risk of windowing — a glassy, see-through center.
Length-to-width · Ideal: A 1.35:1 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 · Closer look: Slightly thick to very 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 · Ideal: D is in the colorless range and faces up white in any metal.
Clarity · Favorable: VS1 is typically eye-clean.
Fluorescence · Ideal: Faint: no meaningful effect on appearance.

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?
