The report asks for a more careful visual review.

What reads well

Crown 38.7° / pavilion 39.6° fall outside the pairing zone associated with strong light return.

Table · Ideal: At 58%, the table sits within the typical 53–59% range for a round brilliant, balancing brightness with fire.
Total depth · Ideal: 62.2% is within the typical 59.5–63% range for a round brilliant, keeping weight where it contributes to face-up size and light return.
Crown angle · Closer look: A 38.7° crown is steeper than the typical 32–36° zone. Steep crowns can add fire, but only pair well with a slightly shallower pavilion.
Pavilion angle · Closer look: 39.6° is shallower than the narrow 40.5–41.3° zone. Shallow pavilions can let light pass straight through, looking glassy.
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: 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.
Cut grade · Favorable: Very Good as issued by IGI, on IGI's own scale. The measured proportions above tell you more than the label.
