GCAL report 362086192

3.59 ct Oval Laboratory-Grown Diamond

80/100 · Considered

A balanced profile with a few questions to carry forward.

What reads well

A 1.91:1 length-to-width ratio is outside the classic oval range; the outline will look more elongated than typical.
Screening only: for this oval, check images or video of the exact stone for the bow-tie (a dark band across the centre) and whether both ends look even.
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 60%, the table sits within the typical 53–63% range for an oval, balancing brightness with fire.
Total depth · Ideal: 60.7% is within the typical 58–63.5% range for an oval, keeping weight where it contributes to face-up size and light return.
Length-to-width · Favorable: A 1.91:1 outline is longer and slimmer than the classic 1.3–1.5:1 range for an oval — a matter of taste, but worth seeing in person.
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: Thin - sl. thick, faceted: a durable girdle thickness that doesn't hide meaningful weight.
Culet · Ideal: None: no visible culet facet when viewed face-up.
Color · Ideal: D 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 GCAL, on GCAL's own scale. The measured proportions above tell you more than the label.

In a face-up video, does the bow-tie flicker as the stone tilts, or stay a fixed dark band across the center?
Can you confirm the stone's weight and measurements match the GCAL report before it is set?
