What reads well

Table · Ideal: At 57%, the table sits within the typical 53–59% range for a round brilliant, balancing brightness with fire.
Total depth · Ideal: 62.3% 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 · Ideal: 35° sits in the 32–36° zone where crown angles typically balance fire and brightness.
Pavilion angle · Ideal: 41.2° is inside the narrow 40.5–41.3° zone where the pavilion returns light most efficiently.
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: Thin to slightly thick, faceted, 3.5%: a durable girdle thickness that doesn't hide meaningful weight.
Culet · Ideal: None: 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: VVS1: inclusions, if any, are only visible under magnification.
Fluorescence · Ideal: None: no meaningful effect on appearance.
Cut grade · Ideal: Excellent as issued by GIA, on GIA's own scale. The measured proportions above tell you more than the label.
