90/100 · Refined

A strong, composed candidate on paper.

What reads well

Crown 35.8° with pavilion 40.8° sits in the well-regarded pairing zone for brightness and fire.
The IGI Excellent cut grade corroborates the measured proportions.
Excellent polish and symmetry, the top finish grades.
E color is in the colorless range.
VS1 clarity is typically eye-clean in a round brilliant.

Depth 63.4% sits outside the preferred round range.
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 56%, the table sits within the typical 53–59% range for a round brilliant, balancing brightness with fire.
Total depth · Closer look: 63.4% is deeper than typical for a round brilliant (59.5–63%). Extra depth holds weight below the girdle, so the stone can face up smaller than its carat weight suggests.
Crown angle · Ideal: 35.8° sits in the 32–36° zone where crown angles typically balance fire and brightness.
Pavilion angle · Ideal: 40.8° 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 · Ideal: E is in the colorless range and faces up white in any metal.
Clarity · Favorable: VS1 is typically eye-clean.
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.
