An unusually disciplined report profile.

What reads well

Crown 36.2° with pavilion 40.7° sits in the well-regarded pairing zone for brightness and fire.
Table 57% and depth 62.5% are within the classic round brilliant range.
The IGI Ideal cut grade corroborates the measured proportions.
Excellent polish and symmetry, the top finish grades.
E color is in the colorless range.

Table · Ideal: At 57%, the table sits within the typical 53–59% range for a round brilliant, balancing brightness with fire.
Total depth · Ideal: 62.5% 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 36.2° 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 · Ideal: 40.7° 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: Medium (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.

Does the steep crown give lively fire without making the center look darker?
Does this HPHT-grown diamond look neutral white beside another stone in daylight, with no gray or blue cast?
