89/100 · Refined

A strong candidate on paper; confirm its light pattern in imagery.

What reads well

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 63%, the table sits within the typical 53–63% range for an oval, balancing brightness with fire.
Total depth · Closer look: 64% 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 1.38:1 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: Slightly Thick To Thick (Faceted): a durable girdle thickness that doesn't hide meaningful weight.
Culet · Ideal: Pointed: no visible culet facet when viewed face-up.
Color · Ideal: D is in the colorless range and faces up white in any metal.
Clarity · Ideal: VVS1: inclusions, if any, are only visible under magnification.
Fluorescence · Ideal: None: no meaningful effect on appearance.

With 64% depth, does this stone face up smaller than a typical 1.50 ct oval?
In a face-up video, does the bow-tie flicker as the stone tilts, or stay a fixed dark band across the center?
Does this HPHT-grown diamond look neutral white beside another stone in daylight, with no gray or blue cast?
Can you show me the inscribed report number under a loupe before it is set?
