Distinctive trade-offs that should be viewed deliberately.

What reads well

The stated 43.9% depth does not match the measurements (about 48.2%). Check the report data.
A 43.9% depth is shallow for a fancy shape; check images for a see-through window in the centre.
Screening only: for this fancy shape, check images or video of the exact stone for the overall light pattern, dark areas and any see-through window.
Treatment status is not stated on the report. For a laboratory-grown diamond, ask whether it is as-grown or post-growth treated.
The shape "Triangular Brilliant" does not match a standard profile, so a conservative general screen was used.

Table · Ideal: At 61%, the table sits within the typical 55–65% range for a fancy shape, balancing brightness with fire.
Total depth · Closer look: 43.9% is shallower than typical for a fancy shape (58–68%). That spreads the stone face-up but raises the risk of windowing — a glassy, see-through center.
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: a durable girdle thickness that doesn't hide meaningful weight.
Culet · Ideal: Pointed: no visible culet facet when viewed face-up.
Color · Ideal: D is in the colorless range and faces up white in any metal.
Clarity · Ideal: VVS2: inclusions, if any, are only visible under magnification.
Fluorescence · Ideal: None: no meaningful effect on appearance.

With a shallow 43.9% depth, can you see a glassy, see-through patch in the center?
Does this CVD diamond show any brown or gray undertone face-up in daylight?
Can you show me the inscribed report number under a loupe before it is set?
