1.01 ct Radiant Laboratory-Grown Diamond

85/100 · Refined

A strong candidate on paper; confirm its light pattern in imagery.

What reads well

The depth 70.5% sits outside the typical radiant range.
Screening only: for this radiant, check images or video of the exact stone for the sparkle pattern (defined flashes or "crushed ice") and any dark or see-through corners.
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 63%, the table sits within the typical 60–70% range for a radiant, balancing brightness with fire.
Total depth · Closer look: 70.5% is deeper than typical for a radiant (61–68%). Extra depth holds weight below the girdle, so the stone can face up smaller than its carat weight suggests.
Length-to-width · Ideal: A 1.42:1 outline is within the classic 1.2–1.5:1 range for a radiant.
Polish · Ideal: Excellent polish is the top finish grade — facets are cleanly executed with nothing that would soften sparkle.
Symmetry · Favorable: Very Good symmetry is a fine result; the difference from Excellent is rarely visible without magnification.
Girdle · Ideal: Slightly thick: 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.
