82/100 · Considered

A balanced profile with a few questions to carry forward.

What reads well

SI2 is often not eye-clean in a round brilliant; view an image or video of this exact stone.
Crown 36.2° / pavilion 41.2° fall outside the pairing zone associated with strong light return.

Table · Ideal: At 59%, the table sits within the typical 53–59% range for a round brilliant, balancing brightness with fire.
Total depth · Ideal: 63% 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: 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: 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 · Favorable: I may show slight warmth, especially next to white metal. Yellow or rose gold tends to complement it.
Clarity · Closer look: SI2: inclusions may be visible to the eye. Confirm with images or video before buying.
Fluorescence · Ideal: None: no meaningful effect on appearance.
Cut grade · Ideal: Excellent as issued by IGI, on IGI's own scale. The measured proportions above tell you more than the label.
