92/100 · Signature

An unusually disciplined report profile.

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 60%, the table sits within the typical 53–63% range for an oval, balancing brightness with fire.
Total depth · Ideal: 62.1% 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 · Ideal: Excellent symmetry is the top finish grade — facets are cleanly executed with nothing that would soften sparkle.
Girdle · Ideal: Medium To Slightly 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 · Favorable: VS1 is typically eye-clean.
Fluorescence · Ideal: None: no meaningful effect on appearance.

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?
