3.00 ct Emerald Laboratory-Grown Diamond

88/100 · Refined

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

What reads well

Face-up spread (10.73 × 6.88 mm) is typical or better for a 3.00 ct emerald cut.
Excellent polish and symmetry, the top finish grades.
D color is in the colorless range.
VS1 clarity is typically eye-clean in an emerald cut.
No fluorescence: no haze risk to weigh.

A 1.56:1 length-to-width ratio is outside the classic emerald cut range; the outline will look more elongated than typical.
A 59.4% depth is shallow for an emerald cut; check images for a see-through window in the centre.
Screening only: for this emerald cut, check images or video of the exact stone for the "hall of mirrors" step pattern, any see-through window under the table and clean 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 · Closer look: A 70% table is larger than typical for an emerald cut (60–69%). Large tables can read bright but flatter, with less fire and contrast.
Total depth · Closer look: 59.4% is shallower than typical for an emerald cut (60–69%). That spreads the stone face-up but raises the risk of windowing — a glassy, see-through center.
Length-to-width · Favorable: A 1.56:1 outline is longer and slimmer than the classic 1.3–1.5:1 range for an emerald cut — 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: a durable girdle thickness that doesn't hide meaningful weight.
Culet · Ideal: Long: a keel-line culet, normal for elongated step and modified cuts.
Color · Ideal: D is in the colorless range and faces up white in any metal.
Clarity · Favorable: VS1 is typically eye-clean, though step cuts show inclusions more readily — worth a close look at the images.
Fluorescence · Ideal: None: no meaningful effect on appearance.

With a shallow 59.4% depth, does the center show a window—a see-through patch instead of crisp, reflecting steps?
With open step facets, is the center completely eye-clean without any visible dark marks?
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?
