2.20 ct Emerald Laboratory-Grown Diamond

83/100 · Considered

A balanced profile with a few questions to carry forward.

What reads well

SI1 in an emerald cut: the open step-cut table makes inclusions easier to see. View an image or video of this exact stone.
A 1.61:1 length-to-width ratio is outside the classic emerald cut range; the outline will look more elongated than typical.
G color in a 2.20 ct emerald cut may show some warmth, especially at the corners.
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 · Ideal: At 63%, the table sits within the typical 60–69% range for an emerald cut, balancing brightness with fire.
Total depth · Ideal: 64% is within the typical 60–69% range for an emerald cut, keeping weight where it contributes to face-up size and light return.
Length-to-width · Favorable: A 1.61:1 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 · Favorable: Very Good symmetry is a fine result; the difference from Excellent is rarely visible without magnification.
Girdle · Ideal: Medium: 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 · Favorable: G is near-colorless and faces up white in most settings, though an emerald cut can show a hint of warmth at the corners.
Clarity · Closer look: SI1 in a step cut often shows inclusions through the open table. Confirm eye-cleanliness with images or video.
Fluorescence · Ideal: None: no meaningful effect on appearance.

Step cuts show inclusions openly—is this SI1 diamond eye-clean through the table from about 10 inches away?
Does this CVD diamond show any brown or gray undertone face-up in daylight?
With Very Good symmetry, are any facet junctions visibly misaligned?
Can you show me the inscribed report number under a loupe before it is set?
