IGI report LG791632855

1.80 ct Round Brilliant Laboratory-Grown Diamond

90/100 · Refined

A strong, composed candidate on paper.

What reads well

Crown 33° with pavilion 40.9° sits in the well-regarded pairing zone for brightness and fire.
The IGI Excellent cut grade corroborates the measured proportions.
Excellent polish and symmetry, the top finish grades.
E color is in the colorless range.
VVS2 clarity: inclusions are not a practical visual factor.

Table 62% and depth 58.8% sit outside the preferred round range.
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 62% table is larger than typical for a round brilliant (53–59%). Large tables can read bright but flatter, with less fire and contrast.
Total depth · Closer look: 58.8% is shallower than typical for a round brilliant (59.5–63%). That spreads the stone face-up but raises the risk of windowing — a glassy, see-through center.
Crown angle · Ideal: 33° sits in the 32–36° zone where crown angles typically balance fire and brightness.
Pavilion angle · Ideal: 40.9° is inside the narrow 40.5–41.3° zone where the pavilion returns light most efficiently.
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 to medium (faceted): a durable girdle thickness that doesn't hide meaningful weight.
Culet · Ideal: Pointed: no visible culet facet when viewed face-up.
Color · Ideal: E 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.
Cut grade · Ideal: Excellent as issued by IGI, on IGI's own scale. The measured proportions above tell you more than the label.

With a shallow 58.8% depth, can you see a glassy, see-through patch in the center?
Does the large table look bright but flat, with less colored fire than you expected?
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?
