A strong, composed candidate on paper.

What reads well

Crown 31.3° / pavilion 41.6° fall outside the pairing zone associated with strong light return.
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 59%, the table sits within the typical 53–59% range for a round brilliant, balancing brightness with fire.
Total depth · Ideal: 61.6% 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 · Favorable: A 31.3° crown is shallower than the typical 32–36° zone, which tends to trade some fire for brightness.
Pavilion angle · Closer look: 41.6° is steeper than the narrow 40.5–41.3° zone. Deep pavilions can leak light through the sides and darken the center.
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 · Favorable: Slightly thick to thick (faceted): durable, on the thicker side for a round brilliant, so a little weight sits in the rim.
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 · Ideal: VVS2: inclusions, if any, are only visible under magnification.
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.
