79/100 · Considered

A balanced profile with a few questions to carry forward.

What reads well

M color in a 3.01 ct Old European cut may show some warmth, especially at the culet.
Screening only: for this Old European cut, check images or video of the exact stone for the broad, chunky antique flash pattern and how the open culet looks face-up.
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 50%, the table sits within the typical 45–56% range for an Old European cut, balancing brightness with fire.
Total depth · Closer look: 66.1% is deeper than typical for an Old European cut (57–66%). Extra depth holds weight below the girdle, so the stone can face up smaller than its carat weight suggests.
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: Thick (faceted): a durable girdle thickness that doesn't hide meaningful weight.
Culet · Ideal: Large: the open culet traditional to an Old European cut, seen face-up as a small circle at the center and part of its antique character.
Color · Closer look: M shows visible warmth. It suits buyers who like a softer, warmer look, and pairs best with yellow or rose gold.
Clarity · Favorable: VS1 is typically eye-clean.
Fluorescence · Ideal: None: no meaningful effect on appearance.
