What reads well

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 58%, the table sits within the typical 53–59% range for a round brilliant, balancing brightness with fire.
Total depth · Ideal: 60.7% 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: 34.9° sits in the 32–36° zone where crown angles typically balance fire and brightness.
Pavilion angle · Closer look: 40.4° is shallower than the narrow 40.5–41.3° zone. Shallow pavilions can let light pass straight through, looking glassy.
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: 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: 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.
Cut grade · Ideal: Ideal as issued by IGI, on IGI's own scale. The measured proportions above tell you more than the label.
