What reads well

A 1.48:1 length-to-width ratio sits in the classic emerald cut range.
Face-up spread (10.17 × 6.87 mm) is typical or better for a 3.00 ct emerald cut.
Table 63% and depth 62% fall in the typical emerald cut range.
Excellent polish and symmetry, the top finish grades.
VVS2 clarity: inclusions are not a practical visual factor.

G color in a 3.00 ct emerald cut may show some warmth, especially at the corners.
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 · Ideal: At 63%, the table sits within the typical 60–69% range for an emerald cut, balancing brightness with fire.
Total depth · Ideal: 62% is within the typical 60–69% range for an emerald cut, keeping weight where it contributes to face-up size and light return.
Length-to-width · Ideal: A 1.48:1 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 · Ideal: Excellent symmetry is the top finish grade — facets are cleanly executed with nothing that would soften sparkle.
Girdle · Ideal: Slightly thick: 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 · Favorable: G is near-colorless and faces up white in most settings, though an emerald cut can show a hint of warmth at the corners.
Clarity · Ideal: VVS2: inclusions, if any, are only visible under magnification.
Fluorescence · Ideal: None: no meaningful effect on appearance.
