IGI report LG759531113

1.52 ct Round Brilliant Laboratory-Grown Diamond

93/100 · Signature

An unusually disciplined report profile.

What reads well

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: 63.3% 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: 35.9° sits in the 32–36° zone where crown angles typically balance fire and brightness.
Pavilion angle · Ideal: 40.9° 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.
