What reads well

Screening only: for this emerald cut, check images or video of the exact stone for the "hall of mirrors" step pattern, any see-through window under the table and clean corners.
Treatment status is not stated on the report. For a laboratory-grown diamond, ask whether it is as-grown or post-growth treated.

Table · Closer look: A 70% table is larger than typical for an emerald cut (60–69%). Large tables can read bright but flatter, with less fire and contrast.
Total depth · Closer look: 69.8% is deeper than typical for an emerald cut (60–69%). Extra depth holds weight below the girdle, so the stone can face up smaller than its carat weight suggests.
Length-to-width · Ideal: A 1.45:1 outline is within the classic 1.3–1.5:1 range for an emerald cut.
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 · Ideal: Medium: a durable girdle thickness that doesn't hide meaningful weight.
Culet · Ideal: Long: a keel-line culet, normal for elongated step and modified cuts.
Color · Ideal: E is in the colorless range and faces up white in any metal.
Clarity · Ideal: VVS2: inclusions, if any, are only visible under magnification.
Fluorescence · Ideal: None: no meaningful effect on appearance.
