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.
Treatment status is not stated on the report. For a laboratory-grown diamond, ask whether it is as-grown or post-growth treated.

Table · Ideal: At 63%, the table sits within the typical 53–63% range for an oval, balancing brightness with fire.
Total depth · Ideal: 61% 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 1.46:1 outline is within the classic 1.3–1.5:1 range for an oval.
Polish · Favorable: Very Good polish is a fine result; the difference from Excellent is rarely visible without magnification.
Symmetry · Favorable: Very Good symmetry is a fine result; the difference from Excellent is rarely visible without magnification.
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: F 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.
